This setting is managed by your administrator.

[cerescornnotes]

I have an issue with enabling Tamper Protection in Windows Defender on my Windows 11 Pro system, version 23H2. Whenever I try to enable it, I receive a message stating, "This setting is managed by your administrator."

I've ensured that I'm signed in as the administrator on my personal account, but still unable to enable Tamper Protection. I even attempted to modify the TamperProtection registry key to force the activation, but encountered permissions issues, preventing me from making changes.

Could someone provide assistance on how to resolve this? Any help would be greatly appreciated.
