[SOLVED] Run command doesn't work on HP computer

[WCarp]

I am trying to help a friend use his HP desktop computer running Windows 10 Pro and found that the Run command doesn't run whether Win + R or clicking on Run from the Start menu. When these operations are attempted, Windows Explorer starts instead. How can this be fixed?

Thanks

have you tried task manager?
open task manager
click file/run new task
window should open letting you run a task and make it admin if need be

right click start button
choose powershell (admin)
type SFC /scannow and press enter
once its completed, copy/paste this command into same window:
Repair-WindowsImage -Online -RestoreHealth
and press enter

SFC fixes system files, second command cleans image files, re run SFC if it failed to fix all files and restart PC
