Your webcam may not work on Windows 10 for several reasons. The common troubleshooting steps apply, but Windows 10 has a new system option that completely disables your webcam in all applications.
Check Windows 10 Camera Options
In Windows 10, the Settings app has some power switches that disable your webcam in all applications. If you disable your webcam here, stationary applications will not be able to use it.
This is a little confusing. In general, the App permissions options under Settings> Privacy mostly affect new Windows 10 apps from the store, also known as UWP apps. But webcam options also affect desktop applications.
If your webcam is not working, go to Settings> Privacy> Camera.
At the top of the window, make sure it says "Camera access for this device is on." If it says that the camera's access is turned off, click the "Change" button and put it to "On." If the camera's access is turned off, Windows and applications on your system will not be able to use the webcam. Not even Windows Hello login will work.
Just below that, make sure that "Let apps access your camera" is also set to "On." If set to Off, no applications on your system – including desktop applications – can view or use the camera. However, the Windows operating system can still use the camera for features like Windows Hello.
This option was changed when Windows 10 was updated in April 2018. Previously, only UWP apps were affected and do not affect traditional desktop applications.
Under "Choose which apps can access your camera", make sure the app that wants to access your camera is not busy and set to "Off." If it appears in this list, set it to "On."
Please note that traditional desktop applications are not listed on this list. Only Store applications are displayed here. Traditional desktop applications can always access your webcam as long as you have enabled the option "Allow access to the camera on this device" and "Allow apps to access the camera" on the entire system.
As long as the above options are correctly set, Windows 10 should not get in the way. It only leaves the traditional webcam's troubleshooting steps.
Make sure your webcam is not disabled by other means
We have covered some other ways to disable your webcam earlier. Aside from just unplugging it, you can disable the webcam on the BIOS or UEFI firmware on some laptops. This option is more common on laptops, as it allows companies to shut down the webcam access safely. If you previously disabled your webcam in BIOS or UEFI firmware, you must enable it from there.
It is also possible to disable the webcam in Windows Device Manager. This prevents it from working until you enable it again. If you previously disabled your webcam in this way, you must return to Device Manager and re-enable the device.

Install or Update Webcam Drivers
Windows 10 Trying to Install device drivers when you automatically connect a device and usually work. But it does not always work properly. In some cases, you may need to download a device driver installer from the webcam manufacturer's website and install it yourself.
Even if you previously downloaded drivers, visit the webcam manufacturer's website and download the latest driver package to update the drivers for your device. The manufacturer's website should also provide additional troubleshooting instructions for your webcam.
Double-checking physical connections
If no applications can view your webcam, it is worth double checking that it is properly connected. We have tried to troubleshoot hardware many times just to realize that we do not plug in a cable properly. It happens.
If you have a USB webcam, make sure that the webcam's USB cable is connected to the computer's USB port. Pull out the plug and replace it to ensure it is firm and not loose. Some webcams have lights that are displayed when connected. If so, check if a light comes on after you connect the webcam. It is also worth trying out another USB port on your computer because a problem with the computer's USB port may cause the webcam to malfunction.
If you have a webcam built into your laptop there is no cable that you can reset. But you should make sure that you have not taken the web. Newer laptops start with built-in protection that lets you slide your webcam when you're not using it.
Select your webcam device
Ok, Windows does not block your webcam, you have the correct drivers installed, and it is properly connected. What could be wrong?
Well, you may need to configure webcam settings in which application you are trying to use. This is especially true if you have multiple video recorder devices connected to your computer. The program you are trying to use can automatically select errors.
In the application you are using, go to the setup screen and look for an option that lets you choose your preferred webcam. For example, in Skype, click the menu> Settings> Audio & Video and select your desired webcam from the "Camera" menu.
If you can not see the webcam at all in an application, then the application can not support your webcam. For example, Windows 10 Store applications (also known as UWP apps) support only new types of webcams. As Microsoft says, Windows 7 webcams can not work in Store apps on Windows 10. But desktop apps still support older types of webcams. If your webcam does not appear in some apps but does it on other apps, the app may not support the webcam.
Skype is particularly strange. On Windows 10, the downloadable version of Skype and the preinstalled version of Skype are almost alike, but the downloadable version can see more types of webcams. This is because the downloadable version is a classic desktop app and the accompanying version is a UWP app.

] If it still does not work
If your webcam still does not work in any programs can only be broken. If it is an external USB webcam, try connecting it to other computers and see if it works.
If you are still within your portable warranty period (if it is built-in) or the webcam warranty period (if it is an external device), contact the manufacturer and see if it can solve your problem.
