Hi Issa_1507
Click your Start Button, then just type cmd
From the resulting list, right click Command Prompt and choose 'Run as Administrator
Paste this command into Command Prompt and hit Enter
attrib +r -s -h C:\User\UP /S /D
When that completes, restart (not shut down) your PC
If that does not work, boot into safe Mode and run command that from there . . .
