mitigate-folina

Mitigates the "Folina"-ZeroDay (CVE-2022-30190) and "Search"-Nightmare (no CVE given at the moment)

This script will backup and then remove the affected registry key (as suggested by Microsoft) to mitigate CVE-2022-30190). If parameterized with "-revert" the script will reimport the key. This can be used when Microsoft releases a patch.

Script must be run as administrator or NT-AUTHORITY\SYSTEM (can be deployed via GPP as a startscript or scheduled task)
