If your PC isn't running well, resetting it might fix the problem. Resetting reinstalls Windows 10, but gives you the option to keep your files. Here are three ways to reset your PC:
Select the Start button, then select Settings > Update & security > Recovery. Under Reset this PC, select Get started.
Restart your PC to get to the sign-in screen, then press and hold down the Shift key while you select the Power icon > Restart in the lower-right hand corner of the screen. After your computer restarts, select Troubleshoot > Reset this PC.
You can also use installation media to reset your PC. See Recovery options in Windows 10 for detailed steps.
