Hello RBR,
I am checking in to see if you have successfully regained administrative access on your device. As we identified, the persistence of "Standard User" restrictions even after a full reset indicates that the device is pulling a restrictive policy from the cloud during setup. The resolution relies on logging into https://www.google.com/search?q=intune.microsoft.com to update the Windows Autopilot Deployment Profile—specifically changing the "User account type" from Standard to Administrator, and verifying your role assignment in https://www.google.com/search?q=entra.microsoft.com under Device Settings. Once those cloud policies are updated, the final "Remove everything" reset will force the device to download the new configuration and correctly apply your Global Administrator privileges.
If the issue has been successfully resolved, please consider accepting the answer as it helps other people sharing the same question benefit too. Thank you!
