File explorer window opens every time I exit full screen

Hi SekkeyWho

Considering you just reinstall Windows 10, you might be missing some pending updates.

Click Start > Settings > Update & security > Windows Updates > Check for updates.

Download and install any pending updates, restart then check if stability is restored.

Try these first to see if they work:

Open Start, type: CMD

Right click CMD

Click Run as administrator

Type in at the prompt OR Copy and Paste these one at a time : (Hit enter after each)

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /ScanHealth

Dism /Online /Cleanup-Image /RestoreHealth

Also run the System File Checker utility:

Open Start, type: CMD

Right click CMD

Click Run as administrator

At the Command Prompt, type: sfc/scannow

This will check for any integrity violations

Restart your system

Check your hard disk for any errors:

Click Start

Type: CMD, from the results, right click Command prompt

Click 'Run as Administrator'

At the Command Prompt, type: chkdsk /r /f

Hit Enter

When you restart your system, your computer will be scanned for errors and attempts will be made to correct them.

Its possible there is an issue with your display driver.

If that does not work:
