Windows Task Manager: The Complete Guide



Windows Task Manager is a powerful tool with useful information, from the total resource usage of your system to detailed statistics for each process. This guide explains all features and terminology in the Task Manager.

This article focuses on the Windows 1

0 Task Manager. However, this also applies to Windows 7. Microsoft has significantly improved Task Manager since the release of Windows 7. 19659003] Starting Task Manager

Windows offers many ways to launch Task Manager. Press Ctrl + Shift + Esc to open the Task Manager with a keyboard shortcut, or right-click on the Windows taskbar and select "Task Manager."

You can also press Ctrl + Alt + Delete and then click Task Manager in the Task Manager screen that appears, or find the shortcut to Task Manager in your Start menu.

The simple view

When you start Task Manager for the first time, a small, simple window appears. This window lists the visible applications running on your desktop, except background applications. You can select an application here and click "End Task" to close it. This is useful when an application is unresponsive, that is, when it is frozen and you can not close it as usual.

You can also right-click an application in this window to access more options: [19659009] Go to : Go to the application window. Bring it to the front of your desktop and put it in focus. This is useful if you are not sure which window is associated with which application.

  • End Task : Stop the process. This works in the same way as the End Task button.
  • Run New Task : Open the Create New Task window where you can specify a program, folder, document, or site address. Windows will open it. 19659010] Always On Top : Make the Task Manager window "always in the foreground" of other windows on your desktop so that you can see it at any time.
  • Open File Location : Open a File Explorer window to display the location of the program .exe file.
  • Online Search : Perform a Bing search for the application name and file name of the program. That way you can see exactly what the program is and what it does.
  • Properties : Open the Properties window for the executable file of the program. Here you can customize the compatibility options and display the version number of the program, for example:
  • When Task Manager is open, a task manager icon appears in your notification area. This shows how many CPU resources (central processing unit) are currently used in your system. You can hover over it to see the memory, disk, and network usage. This is a simple way to monitor the CPU usage of your computer.

    To display the system tray icon without displaying Task Manager on the taskbar, in the full Task Manager interface, click Options> Hide when minimized, and minimize the Task Manager window.

    Task Manager Tabs

    Click "More Details" at the bottom of the simple viewport to see the advanced tools in Task Manager. The complete, tabbed user interface appears. The Task Manager remembers your preferences and will open in the future for the expanded view. If you want to return to the simple view, click on "Less details".

    If you selected More Details, the Task Manager contains the following tabs:

    • Processes : A list of running applications and background processes of your system along with information about CPU, memory, disk, network, GPU and other resources.
    • Performance : Real-time charts that show the total CPU, memory, disk, network, and GPU usage for your system. You can also find many other details here, from the IP address of your computer to the model name of your computer's CPU and GPU.
    • App History : Information about how much CPU and network resource apps your current computer has consumed. This only applies to new UWP apps (Universal Store Windows apps), ie store apps, and not to traditional Windows desktop apps (Win32 apps).
    • Startup : A list of your launcher programs that are the applications Windows launches automatically when you log in to your user account. You can disable startup programs from here, but you can also do this via Settings> Apps> Start.
    • Users : The user accounts currently logged on to your PC, how many resources they use, and what applications they use
    • Details : More detailed information about the processes running on your system. This is basically the traditional Processes tab from the Task Manager on Windows 7.
    • Services : Administration of System Services. You can also find this information in services.msc, the Services Management Console.

    Managing Processes

    The Processes tab provides a comprehensive list of processes running on your system. If you sort them by name, the list is divided into three categories. The Apps group displays the same list of running applications that you see in the simplified "Less details" view. The other two categories are Background Processes and Windows Processes and show processes that are not displayed in the simplified default view of Task Manager.

    For example, tools such as Dropbox, your antivirus program, background update processes, and hardware utilities with the notification area (notification area) appear in the list of background processes. Windows processes include various processes that are part of the Windows operating system, although for some reason some appear under "Background Processes" instead.

    You can right-click a process to see what actions are possible. The following options appear on the shortcut menu:

    • Expand : Some applications, such as Google Chrome, combine several processes. Other applications have multiple windows that are part of a single process. You can select Expand, double-click the process, or click the arrow to the left of it to view the entire process group individually. This option only appears when you right-click a group.
    • Minimize : Minimize an extended group.
    • End task : Stop the process. You can also click the End Task button below the list.
    • Restart : This option only appears when you right-click Windows Explorer. You can restart explorer.exe instead of simply completing the task. In older versions of Windows, you had to quit Task Explorer.exe and then start it manually to troubleshoot problems with the Windows desktop, the taskbar, or the Start menu. Now you can just use this restart option.
    • Resource Values ​​: Here you can choose to view the percentage or exact values ​​for memory, disk, and network. In other words, you can choose to see the exact amount of RAM in MB or the percentage of your system's storage applications.
    • Creating a Backup File : This is a debugging tool for programmers. It captures a snapshot of program memory and saves it to disk.
    • Go to Details : Go to the Details tab to see detailed technical information.
    • Open File Location : Open File Explorer with the selected process .exe file.
    • Search Online : Search for the name of the process on Bing.
    • Properties : Display the Properties window of the .exe file that is associated with the file.

    You should not finish tasks if you do not know what is causing the task. Many of these tasks are background processes that are important to Windows itself. They often have confusing names and you may need to do a web search to find out what they are doing. There is a whole series that explains what different processes do, from conhost.exe to wsappx.

    This tab also provides detailed information about each process and its combined resource consumption. You can right-click the headings at the top of the list and select the columns you want to view. The values ​​in each column are color coded, and a darker orange (or red) color indicates a higher resource usage.

    You can click on a column to sort by it. For example, click on the CPU column to view the running processes CPU usage with the largest CPU hogs on top. The top part of the column also shows the total resource usage of all processes in your system. Drag and drop the columns to reorder them. The available columns are:

    • Type : The category of the process (app, background process, or windows process).
    • Status : When a program seems frozen, "Do Not Respond". appears here. Programs sometimes react after a while and sometimes freeze. If Windows has suspended a program to save energy, a green sheet appears in this column. Modern UWP apps can be suspended to save energy, and Windows can also expose traditional desktop apps.
    • Publisher : The name of the publisher of the program. For example, Chrome shows "Google Inc." and Microsoft Word "Microsoft Corporation".
    • PID : The process ID number that Windows assigned to the process. The process ID can be used by certain functions or system utilities. Windows assigns a unique process ID each time the program starts, and the process ID is one way to distinguish between multiple running processes when multiple instances of the same program are running.
    • Process name : The filename of the process. For example, Explorer is explorer.exe, Microsoft Word is WINWORD.EXE, and Task Manager itself is Taskmgr.exe.
    • Command Line : The full command line used to start the process. This will show you the full path to the EXE file of the process (for example, "C: WINDOWS Explorer.EXE") and any command-line options used to start the program.
    • CPU : The CPU usage of the process, displayed as a percentage of your total available CPU resources.
    • Memory : The physical memory of your system that the process currently uses, in MB or GB.
    • Disk : Disk activity that generates a process is displayed in MB / s. If a process is not currently reading from disk or writing to disk, it will display 0 MB / s.
    • Network : The network usage of a process in the current primary network, displayed in Mbps. [19659010] GPU : The GPU resources (GPU unit) used by a process that are displayed as a percentage of the available resources of the GPU.
    • GPU Engine : The GPU device and engine used by a process. If there are multiple GPUs in your system, you will see which GPU a process is using. The Performance tab tells you which number ("GPU 0" or "GPU 1") is associated with each physical GPU.
    • Power Usage : Estimated power usage of a process taking into account the current CPU disk B. "Very low" when a process does not consume many resources, or "Very high" when a process consumes many resources. When it's high, it means it consumes more power and power shortens battery life when using a laptop.
    • Power Usage Trend : Estimated Implications for Power Consumption Over Time The Power Consumption column displays only current power consumption, but this column plots power consumption over time. For example, if a program occasionally consumes a lot of power consumed, but currently not consuming much power, the column "Power Consumption" may indicate "Very low" and the column "Power Consumption Trend" the value "High" or "Moderate".

    If you right-click the headings, the Resource Values ​​menu also appears The same option that appears when you right-click a single process. Regardless of whether or not you access this option by right-clicking on a single process, the appearance of all processes in the list always changes.

    Task Manager Menu Options

    There are also some useful options in the Task Manager menu bar:

    • File> Execute New Task : Start a program, folder, document, or a Specify network resource with its address. You can also enable "Create this task with administrator privileges" to start the program as an administrator.
    • Options> Always on Top : The Task Manager window is always displayed over other windows while this option is on.
    • Options> Minimize on Use : Task Manager minimizes when you right-click a process and select "Switch To". Despite the odd name, this is just this option. [19659063] Options> Hide when minimized : Task Manager remains active in the notification area (taskbar) when you click the collapse button if you enable this option.
    • View> Update Now : Update the data displayed in Task Manager immediately.
    • View> Update Speed ​​: Select how often the data displayed in the Task Manager is updated: High, Medium, Low, or Paused. If Paused is selected, the data will not be updated until you select a higher frequency or click Update Now.
    • View> Group By Type : When this option is enabled, Processes tab processes are grouped into three categories: Apps, Background Processes, and Windows Processes. If this option is disabled, they appear mixed in the list.
    • View> Expand All : Expand all process groups in the list. For example, Google Chrome uses multiple processes, and these are grouped together in a "Google Chrome" group. You can also expand individual process groups by clicking on the arrow to the left of their name.
    • View> Hide All : Hide all process groups in the list. For example, all Google Chrome processes will only appear in the Google Chrome category.

    Viewing Performance Information

    The Performance tab displays real-time charts showing the use of system resources such as CPU, memory, hard disk, network, and GPU. If you have multiple hard drives, network devices, or GPUs, you can view them all separately.

    The left panel displays small charts, and you can click an option to display a larger chart in the right pane. The graph shows the resource usage in the last 60 seconds.

    In addition to the resource information, the Performance page also displays information about your system's hardware. Here are just a few things that appear in the various windows in addition to resource usage:

    • CPU : The name and model number of your CPU, its speed, the number of cores it has, and whether hardware virtualization features are enabled. It also shows the "uptime" of your system, ie how long your system has been running since the system was last booted.
    • Memory : How much memory you have, how fast you are, and how many RAM slots you have on your computer motherboard. You can also see how much memory is currently filled with cached data. Windows calls this "standby". This data is ready and waiting when your system needs it, but Windows automatically caches the cached data and frees up memory when more memory is needed for another task.
    • Disk : The name and model number of your hard disk drive, size and current read and write speeds.
    • Wi-Fi or Ethernet : Windows displays the name of the network adapter and its IP addresses (both IPv4 and IPv6 addresses). For Wi-Fi connections, you can also view the Wi-Fi standard used for the current connection. 802.11ac.
    • GPU : The GPU panel displays separate charts for different types of activities, for example, 3D vs. Video coding or decoding. The GPU has its own built-in memory, so the GPU memory usage is also displayed. You can also see the name and model number of your GPU and the video driver version you are using. You can monitor GPU usage directly from Task Manager without third-party software.

    You can also turn this window into a smaller window if you want to see it on the screen at any time. Simply double-click anywhere in the blank white area in the right pane, and you'll see a floating, always-on-top window with that graph. You can also right-click on the graph and select "Graph Survey View" to activate this mode.

    The Open Resource Monitor button at the bottom of the window opens the Resource Monitor tool for more detailed information about GPU, memory, disk, and network usage by each running process.

    Consulting App History

    The App History tab only applies to Universal Windows Platform (UWP) apps. It does not display information about traditional Windows desktop apps, so most users do not find this useful. The list shows the UWP applications as well as the CPU time and network activity that the application has generated since that date. You can right-click the headings here for more options to gain more insight into network activity:

    • CPU Time : The amount of CPU time the program used within this time frame.
    • Network : The total amount of data that the program has transmitted over the network during this time.
    • Metered Network : The amount of data that is transmitted through the metering networks. You can set a network as measured to store data on. This option is for networks where you have limited data, such as a mobile network to which you are connected.
    • Tile Updates : The amount of data that the program downloaded to display updated live tiles in the Windows 10 Start menu
    • Unmeasured Network : The amount of data that is transmitted over unmeasured networks.
    • Downloads : The amount of data downloaded by the program on all networks.
    • Uploads : The amount of data that the program has uploaded to all networks.

    Controlling Startup Applications

    The Home tab is the launcher manager built into Windows 10. It lists all applications that Windows automatically launches for your current user account. For example, programs appear in your Startup folder and programs that you want to start in the Windows Registry.

    To disable a launcher, right-click on it and select "Disable" or click the "Disable" button. To enable it again, click on the "Activate" option, which will be shown here instead. You can also use the Settings> Apps> Startup interface to manage startup programs.

    In the upper right corner of the window, some systems display a "Latest BIOS time". This shows how long your BIOS (or your UEFI firmware) needed to initialize your hardware when you last started the PC. This is not displayed on all systems. You will not see it if your PC's BIOS does not report to Windows this time.

    As usual, you can right-click on the headings and enable additional columns. The columns are:

    • Name : The name of the program.
    • Publisher : The name of the publisher of the program.
    • Status : "Enabled" is displayed here when the program is automatically activated will start when you log in. If you disabled the startup task, it will show "Disabled".
    • Startup Impact : An estimate of the CPU and disk resources used by the program at startup. Windows measures and keeps track of this in the background. An easy program shows "Low" and an extensive program shows "High". Disabled programs display "None". You can speed up the boot process by causing programs to have a "high" start than by disabling programs with a low impact.
    • Startup type : Indicates whether the program is due to a registry entry ("Registration") or because it is in your startup folder ("Folder"),
    • Disk I / O at startup : The Disk activity that the program runs at startup, in MB. Windows measures and records this every time it starts up.
    • CPU at Startup : The CPU time a program uses at startup, in ms. Windows measures and records this at boot time.
    • Running Now : The word "Running" appears here when a launcher is in progress. If this column appears as an entry for a program, the program has been shut down or you have closed it yourself.
    • Disabled Time : For startup programs that you have disabled, the date and time of disabling a program are displayed here
    • Command Line : This displays the full command line that launches the launcher, including all command line options.

    User Verification

    The Users tab displays a list of logged in users and their running processes. If you are the only person logged in to your Windows PC, only your user account will be shown here. If other people have logged in and then locked their sessions without logging off, they will also be displayed. Locked sessions are displayed as disconnected. It also displays the CPU, memory, disk, network, and other system resources used by processes running under any Windows user account.

    You can disconnect a user account by right-clicking it and selecting "Disconnect," or force it to log out by right-clicking it and choosing "Logout." The Disconnect option terminates the desktop connection, but the programs continue to run and the user can log in again-for example, locking a desktop session. With the option "Logout" all processes are aborted, eg. For example, logging out of Windows.

    You can also manage the processes of another user account from here if you want to end a task that belongs to another active user account.

    If you're right-Click on the headings. The available columns are:

    • ID : Each logged in user account has its own session ID. Session "0" is reserved for system services, while other applications can create their own user accounts. You do not normally need to know this number, so it is hidden by default.
    • Session : This is the type of session. For example, "Console" is displayed when accessed on your local system. This is especially useful for server systems running remote desktops.
    • Client Name : The name of the remote client system that accesses the session when remote access is being accessed.
    • Status : The status of the session If, for example, a user's session is locked, the status will be "Disconnected".
    • CPU : CPU used by the user's processes.
    • Memory : Total amount of memory used by the user's processes.
    • Volume : Total number of volume activity associated with user processes.
    • Network : Total activity of the network from the user processes.

    Managing Detailed Processes

    This is the most detailed task manager area. It's like the Processes tab, but it provides more information and shows the processes of all user accounts in your system. If you used the Windows 7 Task Manager, you know this. The same information is displayed on the Processes tab in Windows 7.

    You can right-click processes here to access additional options:

    • End Task : Stop the process. This is the same option as on the Processes tab.
    • End process tree : End process and all processes created by the process.
    • Set Priority : Set a priority for the process: Low, Under Normal, Normal, About Normal, High, and Real. Processes start with normal priority. Lower priority is ideal for background processes and higher priority is ideal for desktop processes. Microsoft recommends, however, not to deal with the real-time priority.
    • Set affinity : Set the processor affinity of a process, that is, which processor a process is running on. By default, processes are run on all processors in your system. You can use this to limit a process to a specific processor. For example, this is sometimes helpful for legacy games and other programs that assume you have only a single CPU. Even if you have a single CPU in your computer, each core will be displayed as a separate processor.
    • Waiting Chain Analysis : Indicate which threads are waiting in the processes. This shows you which processes and threads are waiting for the use of a resource that is being used by another process, and is a useful debugging tool for programmers to diagnose hangups.
    • UAC Virtualization : Enable or disable virtualization of User Account Control (UAC) for a process. This feature fixes applications that require administrator access by virtualizing access to system files and redirecting file and registry access to other folders. It is mainly used by older programs, eg. For example, Windows XP programs that were not written for modern versions of Windows. This is a debugging option for developers who do not need to change.
    • Erstellen einer Sicherungsdatei : Erfassen Sie eine Momentaufnahme des Programmspeichers und speichern Sie sie auf der Festplatte . Dies ist ein nützliches Debugging-Tool für Programmierer.
    • Dateispeicherort : Öffnet ein Datei-Explorer-Fenster, in dem die ausführbare Datei des Prozesses angezeigt wird.
    • Online-Suche : : Suche nach Bing Name des Prozesses.
    • Eigenschaften : Anzeigen des Eigenschaftsfensters der Exe-Datei des Prozesses.
    • Gehe zu Dienst (e) : Zeigen Sie die mit dem Prozess verbundenen Dienste auf der Registerkarte Dienste an. Dies ist besonders nützlich für svchost.exe-Prozesse. Die Dienste werden hervorgehoben.

    Wenn Sie mit der rechten Maustaste auf die Überschriften klicken und "Spalten anzeigen" auswählen, wird eine viel längere Liste von Informationen angezeigt, die Sie hier anzeigen können, einschließlich vieler Optionen, die nicht angezeigt werden. t Auf der Registerkarte Prozesse verfügbar.

    Dies bedeutet, was jede mögliche Spalte bedeutet:

    • Paketname : Bei UWP-Apps (Universal Windows Platform) wird hier der Name des App-Pakets angezeigt, aus dem der Prozess stammt. Bei anderen Apps ist diese Spalte leer. UWP-Apps werden im Allgemeinen über den Microsoft Store vertrieben.
    • PID : Die eindeutige Prozess-ID-Nummer, die diesem Prozess zugeordnet ist. Dies ist dem Prozess und nicht dem Programm zugeordnet. Wenn Sie beispielsweise ein Programm schließen und erneut öffnen, erhält der neue Programmprozess eine neue Prozess-ID-Nummer.
    • Status : Dies zeigt an, ob der Prozess ausgeführt wird oder ausgesetzt, um Energie zu sparen. Windows 10 setzt UWP-Apps, die Sie nicht zum Speichern von Systemressourcen verwenden, immer aus. Sie können auch steuern, ob Windows 10 herkömmliche Desktop-Prozesse ausgesetzt wird.
    • Benutzername : Der Name des Benutzerkontos, das den Prozess ausführt. Hier werden häufig Systembenutzerkontonamen wie SYSTEM und LOCAL SERVICE angezeigt.
    • Sitzungs-ID : Die eindeutige Nummer, die der Benutzersitzung zugeordnet ist, die den Prozess ausführt. Dies ist die gleiche Nummer, die für einen Benutzer auf der Registerkarte Benutzer angezeigt wird.
    • Jobobjekt-ID : Das "Jobobjekt, in dem der Prozess ausgeführt wird." Jobobjekte bieten eine Möglichkeit, Prozesse zu gruppieren, sodass sie als verwaltet werden können eine Gruppe.
    • CPU : Der Prozentsatz der CPU-Ressourcen, die der Prozess derzeit für alle CPUs verwendet. Wenn keine andere CPU-Zeit verwendet wird, zeigt Windows hier den System Idle-Prozess an. Wenn der Systemleerlaufprozess 90% Ihrer CPU-Ressourcen verwendet, bedeutet dies, dass andere Prozesse in Ihrem System insgesamt 10% verwenden, und der Prozess war zu 90% im Leerlauf.
    • CPU-Zeit : Die Gesamtprozessorzeit (in Sekunden), die ein Prozess verwendet hat, seit er ausgeführt wurde. Wenn ein Prozess geschlossen und neu gestartet wird, wird dies zurückgesetzt. Dies ist eine gute Methode, um CPU-hungrige Prozesse zu erkennen, die sich momentan im Leerlauf befinden.
    • Cycle : Der Prozentsatz der CPU-Zyklen, die der Prozess derzeit für alle CPUs verwendet. Es ist unklar, wie sich das genau von der CPU-Spalte unterscheidet, da die Dokumentation von Microsoft dies nicht erklärt. Die Zahlen in dieser Spalte sind jedoch im Allgemeinen der CPU-Spalte sehr ähnlich, daher ist es wahrscheinlich, dass eine ähnliche Information anders gemessen wird.
    • Arbeitssatz (Speicher) : Die Menge an physischem Speicher, die der Prozess derzeit verwendet.
    • Peak Working Set (Speicher) : Die maximale Menge an physischem Speicher, die der Prozess verwendet hat.
    • Working Set Delta (Memory) : Die Änderung des Working Set-Speichers seit der letzten Aktualisierung der Daten hier.
    • Arbeitsspeicher (aktives privates Arbeitsset) : Die Menge an physischem Arbeitsspeicher, die vom Prozess verwendet wird und nicht von anderen Prozessen verwendet werden kann. Bei Prozessen werden häufig einige Daten zwischengespeichert, um den Arbeitsspeicher besser zu nutzen. Der Speicherplatz kann jedoch schnell aufgegeben werden, wenn ein anderer Prozess dies erfordert. Diese Spalte schließt Daten aus angehaltenen UWP-Prozessen aus.
    • Arbeitsspeicher (privater Arbeitssatz) : Die Menge an physischem Arbeitsspeicher, die vom Prozess verwendet wird und nicht für andere Prozesse verwendet werden kann. Diese Spalte schließt Daten aus angehaltenen UWP-Prozessen nicht aus.
    • Arbeitsspeicher (gemeinsam genutzter Arbeitssatz) : Die Menge an physischem Arbeitsspeicher, die vom Prozess verwendet wird, der bei Bedarf von anderen Prozessen verwendet werden kann.
    • Commit-Größe ]: Die Menge an virtuellem Speicher, die Windows für den Prozess reserviert.
    • Paged Pool : Die Menge an auslagerungsfähigem Kernelspeicher, die der Windows-Kernel oder die Treiber für diesen Prozess zuordnen. Das Betriebssystem kann diese Daten bei Bedarf in die Auslagerungsdatei verschieben.
    • NP-Pool : Die Menge an nicht auslagerungsfähigem Kernelspeicher, die der Windows-Kernel oder die Treiber für diesen Prozess zuordnen. Das Betriebssystem kann diese Daten nicht in die Auslagerungsdatei verschieben.
    • Seitenfehler : Die Anzahl von Seitenfehlern, die durch den Prozess generiert wurden, seit er ausgeführt wurde. Diese treten auf, wenn ein Programm versucht, auf einen Speicher zuzugreifen, dem es derzeit noch nicht zugeordnet ist, und sind normal.
    • PF Delta : Die Änderung der Anzahl der Seitenfehler seit der letzten Aktualisierung.
    • Basispriorität : Die Priorität des Prozesses – dies kann beispielsweise Niedrig, Normal oder Hoch sein. Windows prioritizes scheduling processes with higher priorities. System background tasks that aren’t urgent may have low priority compared to desktop program processes, for example.
    • Handles: The current number of handles in the process’s object table. Handles represent system resources like files, registry keys, and threads.
    • Threads: The number of active threads in a process. Each process runs one or more threads, and Windows allocates processor time to them. Threads in a process share memory.
    • User objects: The number of “window manager objects” used by the process. This includes windows, menus, and cursors.
    • GDI objects: The number of Graphics Device Interface objects used by the process. These are used for drawing the user interface.
    • I/O reads: The number of read operations performed by the process since it started. I/O stands for Input/Output. This includes file, network, and device input/output.
    • I/O writes: The number of write operations performed by the process since it started.
    • I/O other: The number of non-read and non-write operations performed by the process since it started. For example, this includes control functions.
    • I/O read bytes: The total number of bytes read by the process since it started.
    • I/O write bytes: The total number of bytes written by the process since it started.
    • I/O other bytes: The total number of bytes used in non-read and non-write I/O operations since the process started.
    • Image path name: The full path to the process’s executable file.
    • Command line: The exact command line the process was launched with, including the executable file and any command-line arguments.
    • Operating system context: The minimum operating system the program is compatible with if any information is included in the application’s manifest file. For example, some applications might say “Windows Vista,” some “Windows 7,” and others “Windows 8.1”. Most won’t display anything in this column at all.
    • Platform: Whether this is a 32-bit or 64-bit process.
    • Elevated: Whether the process is running in elevated mode—in other words, with Administrator—permissions or not. You will see either “No” or “Yes” for each process.
    • UAC virtualization: Whether User Account Control virtualization is enabled for the process. This virtualizes the program’s access to the registry and file system, letting programs designed for older versions of Windows run without Administrator access. Options include Enabled, Disabled, and Not Allowed—for processes that require system access.
    • Description: A human-readable description of the process from its .exe file. For example, chrome.exe has the description “Google Chrome,” and explorer.exe has the description “Windows Explorer.” This is the same name displayed on the Name column in the normal Processes tab.
    • Data execution prevention: Whether Data Execution Prevention (DEP) is enabled or not for the process. This is a security feature that helps protect applications from attacks.
    • Enterprise context: On domains, this shows what enterprise context an app is running in. It could be in an enterprise domain context with access to enterprise resources, a “Personal” context without access to work resources, or “Exempt” for Windows system processes.
    • Power throttling: Whether power throttling is enabled or disabled for a process. Windows automatically throttles certain applications when you’re not using them to save battery power. You can control which applications are throttled from the Settings app.
    • GPU: The percentage of GPU resources used by the process—or, more specifically, the highest utilization across all GPU engines.
    • GPU engine: The GPU engine the process is using—or, more specifically, the GPU engine the process is using the most. See the GPU information on the Performance tab for a list of GPUs and their engines. For example, even if you only have one GPU, it likely has different engines for 3D rendering, encoding video, and decoding video.
    • Dedicated GPU memory: The total amount of GPU memory the process is using across all GPUs. GPUs have their own dedicated video memory that’s built-in on discrete GPUs and a reserved portion of normal system memory on onboard GPUs.
    • Shared GPU memory: The total amount of system memory shared with the GPU the process is using. This refers to data stored in your system’s normal RAM that’s shared with the GPU, not data stored in your GPU’s dedicated, built-in memory.

    Working With Services

    The Services tab shows a list of the system services on your Windows system. These are background tasks that Windows runs, even when no user account is signed in. They’re controlled by the Windows operating system. Depending on the service, it may be automatically started at boot or only when necessary.

    Many services are part of Windows 10 itself. For example, the Windows Update services downloads updates and the Windows Audio service is responsible for sound. Other services are installed by third-party programs. For example, NVIDIA installs several services as part of its graphics drivers.

    You shouldn’t mess with these services unless you know what you’re doing. But, if you right-click them, you’ll see options to Start, Stop, or Restart the service. You can also select Search Online to perform a Bing search for information about the service online or “Go to Details” to show the process associated with a running service on the Details tab. Many services will have a “svchost.exe” process associated with them.

    The Service pane’s columns are:

    • Name: A short name associated with the service
    • PID: The process identifier number of the process associated with the service.
    • Description: A longer name that provides more information about what the service does.
    • Status: Whether the service is “Stopped” or “Running.”
    • Group: The group the service is in, if applicable. Windows loads one service group at a time at startup. A service group is a collection of similar services that are loaded as a group.

    For more information about these services, click the “Open Services” link at the bottom of the window. This Task Manager pane is just a less powerful services administration tool, anyway.

    Process Explorer: A More Powerful Task Manager

    If the built-in Windows Task Manager isn’t powerful enough for you, we recommend Process Explorer. This is a free program from Microsoft; it’s part of the SysInternals suite of useful system tools.

    Process Explorer is packed with features and information not included in the Task Manager. You can view which program has a particular file open and unlock the file, for example. The default view also makes it easy to see which processes have opened which other processes. Check out our in-depth, multi-part guide to using Process Explorer to learn more.
