Unable to log in as a new local AD user on computers upgraded from Windows 10 Pro to Windows 11 Pro

Question

I have been upgrading some computeres to Windows 11. They are all on a local AD. It works fine, as long as I just log on as a user that has been logged in before the upgrade.

But if I try to log in as another AD-user, I get an error (translated from Danish): "The service User profile service was not logged on. User profile can't be loaded".

In the profile folder for attempted users I see only "Desktop" and "Documents". No NTUSER.DAT or other files.

I suspect that it's a problem with permissions but I have not been albe to solve the problem.

Does anyone have a suggestion?

Answer 1

This typically happens when the default profile, stored in C:\Users\Default, has incorrect permissions or is corrupt in some way.

Default Profile Permissions
The the directory C:\Users\Default inherits permissions from its parent folder, C:\Users. This results in SYSTEM and Administrators having full control, while Users and Everyone have read permissions.

Fixing a Corrupt Default Profile
The easiest way to fix a corrupt default profile is to delete the content of C:\Users\Default and copy it from a working system. Make sure, though, that the machine you copy from has the same operating system version and language.

Please also disable any Antivirus program you may have temporary.

Also, I recommend that you post your question on the windows 11 forum, because there you will be greeted by an engineer from the windows 11 team, who has more recent information to pass on to you, to do this just use the link below and select the top option called "Ask a question" and describe the entire problem, including images:
