Hello @oQcS3JJ2xdjHwF67
This is likely because some GPO that is preventing this machines. Even if you disabled the inheritance, the machines may retain some GPO settings. To ensure what is applied, run a GPRESULT /H OUTPUT.HTML and in that output file you will see both User and Computer policies applied.
The remaining policies may be still stored in the registry, you can try to delete the next keys (after taking a registry backup, for safety):
Delete the "HKLM\Software\Policies\Microsoft" Key (looks like a folder).
Delete the "HKCU\Software\Policies\Microsoft" Key
Delete the "HKCU\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects" Key.
Delete the "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies" Key.
then execute: gpupdate /force /boot (from an elevated command prompt)
Hope this helps with your query,
