Microsoft says Windows 10 is a "service," and the company regularly updates it with security patches, bug fixes, and new features. Updates usually run automatically in the background. So, decrypt the following: When Windows is installed.
How often does Windows 1
0 check for updates?
Windows 10 checks for updates once a day. This happens automatically in the background. Windows does not always check for updates at the same time, but changes the schedule by several hours to ensure that Microsoft's servers are not overwhelmed by an army of PCs, all looking for updates at the same time.
When Windows finds updates It automatically downloads and installs them.
Although Windows 10 checks for updates once a day, it does not mean that it will be installed daily. Microsoft does not publish Windows updates daily, so Windows Update often does not provide updates and install anything.
Definition Updates Several Times a Day
 Microsoft's Windows Defender application, now called Windows Security, is an anti-malware (anti-virus) application built into Windows 10. It runs automatically in the background and protects your PC. If you install another antivirus program, the built-in Windows antivirus program disables itself and makes your antivirus dialer work.
Like all security applications, Microsoft's anti-virus program requires periodic definition updates to detect and intercept the most recently discovered malware. These updates are small and fast and do not require a reboot. You will not even notice that your PC installs them, unless you open the Windows Update page under Settings and keep an eye on them.
To verify that any definition updates have been installed, go to Settings> Update & Security> Windows Update View the update history, scroll down, and expand Definition Updates.
You can check the frequency of definition definition installation by going to Settings> Update and Security> Windows Update> View Update History, scrolling, and the Definition Updates section.

Driver Updates Occur Occasionally
Hardware drivers are the bits of software that activate hardware devices such as sound, Wi-Fi, graphics, printers and other PC components. Hardware manufacturers sometimes release new versions of these drivers with fixes or other improvements.
Windows Update also provides hardware driver updates for your PC. Hardware manufacturers give Microsoft new hardware drivers, and Windows Update downloads them to your PC. How often your PC receives driver updates depends on the hardware devices it contains and how often the hardware manufacturers publish updates.
Depending on the driver, you may need to restart your PC for driver updates.
For a list of installed driver updates, see "Driver Updates" under Settings> Update & Security> Windows Update> View Update History.
Cumulative Updates Occur Once a Month
Microsoft releases a "Quality Update" for Windows every second Tuesday of the month called "Patch Tuesday". Tuesday). These are large updates that contain security updates and other fixes. They are called cumulative updates because they bundle a variety of fixes-even fixes from previous updates-so only a large cumulative update needs to be installed, even if your PC is turned off for a few months.
Technically, it's a bit more complicated than this. Patch Tuesday's cumulative update is called a "B update," as it will be released in the second week of the month. Updates for "C" and "D" will also be released in the third and fourth week of the month. These include bug fixes and other enhancements that you can only get if you manually click the "Check for Updates" button. If you never do, you will receive these bug fixes in the next Patch B update next Tuesday.
Cumulative updates require a reboot. You are touching important files that can not be edited while Windows is running.
You can also view the list of cumulative updates that Windows has found on the Update History page. Go to Settings> Update and Security> Windows Update> Update History, scroll down and expand "Quality Updates."

Out-of-Band Updates Arrive in Emergencies
While Microsoft typically waits for the release of security updates as part of Patch Tuesday's B updates once a month, sometimes it does "out" releases -of-band updates. These are called "published outside the normal schedule".
These are generally released in emergencies – for example, when a zero-day safety bug is exploited in the wild and the problem needs to be addressed immediately. 19659006] These updates usually also require a reboot.
Function updates come every six months
Microsoft also releases large major versions of Windows 10 once every six months. It calls these "feature updates". They contain many changes and improvements. For example, the Windows 10 update of April 2019 adds a lightweight desktop theme with a new default desktop wallpaper and many other minor changes, including an improved lookup for boot menus and basic improvements that make Windows 10 faster to run.  These do not always come out right away. Microsoft throttles it and just tries to provide an update to your PC if the company thinks your hardware is doing well. You may not get them every six months if you do not care to look for them. For example, the October 2018 update of Windows 10 at the end of February 2019 is not yet available on most Windows 10 PCs.
These major updates always require a reboot. They require a longer installation process, so you spend more time staring at a blue screen while the process is complete. The duration of the update process depends on the speed of your PC and the update. Microsoft has accelerated the installation process in recent releases.
If you see a screen titled "Working on Updates" that says "Your PC will be restarted several times." Windows will likely install a feature update.
As for the updates for C and D This update is generally offered after the release, if you click "Look for" in the Windows Update screen under Settings Updates. "This makes you a" searcher ", and Microsoft will give you the fix, even if it does not I think this is a weird fix.
You can see the most recently installed feature update on the Update History screen. See "Feature Updates" at the top of the Settings> Update & Security> Windows Update> View Update History screen.
Controlling Windows Updates
Windows 10 updates automatically and does not give you nearly as much control as Windows 7. Especially on Windows 10 Home.
You can still prevent Windows from automatically installing updates and restarting the tag in certain hours. Just change the "active hours" at the times you use your PC. For example, if you regularly use your PC from 6 pm. Make sure they are marked as active hours. During this time, no updates of Windows 10 will be installed. You can set up to 18 hours per day as active hours.
To prevent Windows automatically downloading and installing updates for a connection, you can set the connection to be measured. Windows downloads only certain important small updates and does not automatically load and install most updates. This setting is for storing data for connections with limited data. However, you can enable it for each connection, including a wired Ethernet connection.
Windows 10 Professional users can also access additional updates to suspend, postpone, or otherwise delay updates they are more tested on consumer PCs. Finally, on Windows 10 Home, you can also suspend updates when the April 2019 update arrives.
