Can't locate or launch the Camera app after updating to Windows 10? If the Camera app stops functioning or anything goes wrong, here are three quick fixes to get it operating again.
Step 1: Modify the Camera App's Privacy Settings
If the Camera app no longer works, you should check your privacy settings to see if they are blocking the Camera app from accessing your camera.
To do so, launch the Settings app and go to the Privacy section. On the left, choose Camera from the App permissions section. You must enable the option "Allow applications to access your camera" on the right panel. Scroll down to find the Camera app and allow it access to the camera.
Step 2: Reinstall the Camera Application
Reinstalling the Camera app may return anything to its original condition, which may be the most effective solution to resolve the Camera not functioning problem. To remove the Camera app, right-click the Start button and choose Windows PowerShell (Admin). Fill in the blanks using the following command:
Remove-AppxPackage *Microsoft.WindowsCamera* | Get-AppxPackage *Microsoft.WindowsCamera*
