Hi everyone, I created a specific rule to block WinRAR given the recent CVE-2025-8088; the rule targeted the WinRAR.exe file, and the system automatically created default rules for the Windows and Program Files folders.
AppLocker WinRAR

I immediately noticed that almost all applications were blocked.
This app il locked by admin Restoring access to applications and the system wasn't easy.

WinRAR Hash

I then tried creating a rule based on the file hash. This didn't block all applications like before, but I can still use WinRAR.
