Hi, I’m also struggling with tamper protection and GPOs. When tamper protection registry value is ‘1’ (and not changeable by admin), GPOs pretend to work (they appear in gpresult –> applied GPOs) but its content (settings) are not listed/used (also seen in gpresult). Only when I disable tamper protection (in German: Manipulationsschutz) via GUI all GPO Settings are applied as they should.
Do you have any ideas how to solve it? Editing the regkey via GPO doesn’t work, changing regkey via software distribution (SYSTEM account) does not work reliable (or Maybe is overwritten instantly). Manual changing in GUI is not very helpful when deploying remote…

Testing with Win10x64_1909, German, Enterprise Edition, Domain Member).

Thanks,
Ben

I originally had Tamper Protection turned Off (TamperProtection = 0)
After turning it on in Windows Security, the Registry Entry jumped to 5
After disabling it again, it jumped to 4.
After that it toggles between 4 and 5

OS is Windows 10 1909 Pro (Standalone Device, not in Domain, not using Microsoft Account, German Language)
