How to Fix “Your IT Administrator Has Limited Access” Error in Windows Security

1. Force Windows to Repair the Missing Folder
This command tells Windows to look at its own internal backup (the WinSxS store) and restore the missing SecurityHealth files.

Click Start, type cmd, right-click it, and select Run as Administrator.

Copy and paste this command and press Enter:
dism /online /cleanup-image /restorehealth

Wait for it to reach 100% (this can take 10-15 minutes).

Immediately after, paste this and press Enter:
sfc /scannow

Restart your computer.
