Your webcam may not work on Windows 10 for a variety of reasons. The usual troubleshooting steps apply, but Windows 10 has a new system-wide option that completely disables your webcam in all applications.
Checking Windows 10 camera options
On Windows 1
This is a bit confusing. In general, most of the app permission options in Settings> Privacy affect new Windows 10 apps from the store, also known as UWP apps. However, the webcam options also affect desktop apps.
If your webcam is not working, go to Settings> Privacy> Camera.
At the top of the window, make sure "Camera access is turned on for this device." If camera access is disabled, click the "Change" button and set the option to "On." If camera access is disabled, Windows and applications on your system can not use the webcam Not even the Windows Hello login works.
Make sure that "Allow apps to access your camera" is also set to "On" If this option is disabled, no applications are displayed System – including desktop applications – can see or use your camera, but the Windows operating system can still use your camera for features such as Windows Hello.
This option was used with changed from April 108 to Windows 10. So far, only UWP apps have been affected and traditional desktop applications have not.
Under "Choose which apps can access your camera", make sure the app that wants to access your camera is not set to "Off". If it appears in this list, set it to "On".
Note that traditional desktop applications do not appear in this list. Only store applications are shown here. Traditional desktop applications can always access your webcam as long as you have enabled the system-wide options "Allow access to the camera on this device" and "Allow apps to access your camera".
As As long as the above options are set correctly, Windows 10 should not be in the way. The traditional troubleshooting steps for the webcam are retained.
Making sure your webcam is not otherwise disabled
We've discussed a few ways to disable your webcam in the past. Not only can you easily disconnect the webcam from the network, but also disable it on the screen of the BIOS or UEFI firmware settings on some laptops. This option is more common on business laptops because it allows businesses to safely disable access to the webcam. If you previously disabled your webcam in the BIOS or UEFI firmware, you must re-enable it from there.
The webcam device can also be disabled in the Windows Device Manager. This will prevent it from working until you reactivate it. If you previously disabled your webcam in this manner, you must return to Device Manager and reactivate the device.

Installing or updating webcam drivers
Windows 10 Attempts to install device drivers when you automatically connect a device, and it usually works. But it does not always work right. In some cases, you may need to download and install a device driver installation package from the webcam manufacturer's website.
Even if you have already downloaded drivers, visit the website of the webcam manufacturer and download the latest driver package. Update your device drivers. The manufacturer's website should also contain additional troubleshooting instructions for your particular webcam.
Check physical connections
If no application can see your webcam, it is advisable to check the webcam correctly. We've often tried hardware troubleshooting only to find that we did not connect a cable properly. It happens.
If you have a USB webcam, make sure the webcam's USB cable is connected to your computer's USB port. Pull out the plug and reconnect it to make sure it is tight and not loose. Some webcams have LEDs that appear when connected. If this is the case, you will need to determine if a light lights up after connecting the webcam. It's also worth trying another USB port on your computer, as a problem with your computer's USB port could cause the webcam to malfunction.
If you have a webcam installed in your laptop, you will not be able to reset a cable. However, you should make sure that you have not covered the webcam accidentally. Newer laptops start using built-in covers that you can slide over your webcam when you're not using them.
Select your webcam device
Okay, Windows is not blocking your webcam. You have the correct drivers installed and it is securely connected. What could be wrong?
You may need to configure the webcam settings in the applications you want to use. This is especially true if you have multiple video capture devices connected to your PC. The application you are using may automatically pick the wrong one.
In the application you are using, go to the Settings screen and look for an option to choose your preferred webcam. For example, in Skype, click Menu> Settings> Audio & Video, and choose your preferred webcam from the Camera menu.
If you can not see the webcam in an application at all Application may not support your webcam. For example, Windows 10 Store applications (also known as UWP apps) only support newer webcam types. As Microsoft says, Windows 7 webcams may not work in store apps on Windows 10. However, desktop apps still support older webcam types. If your webcam is not displayed in some apps but in other apps, the app may not support the webcam.
Skype is especially funny. On Windows 10, the downloadable version of Skype and the preinstalled version of Skype are almost identical. However, the downloadable version can display more types of webcams. This is because the downloadable version is a classic desktop app and the included version is a UWP app.

If your webcam still does not work in all applications they may be broken. If it is an external USB webcam, try connecting it to other PCs and checking if it works.
If you are still within the warranty period of your laptop (if installed) or the warranty of the webcam (if it is an external device), contact the manufacturer and see if it can resolve the problem.
