Lets try to scan for system file corruption. Then we look to clean up the image then scan again just in case.
For starters press Start and enter cmd then start it with rightclick as administrator.
In the cmd pls enter each of the following command lines as a whole as one command. Copy them with CRTL + C and paste them into the cmd with CRTL + V or rightclick to avoid spelling mistakes. Each of those might take a while. If they throw you an error kindly report it back to me in your next mesage.
sfc /scannow
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /RestoreHealth
sfc /scannow
