Hello hasanemresatilmis​,

Thank you for the detailed guide, and sorry for the delay in getting back to you.

I checked the registry as instructed, but the SID key for the local Administrator account (including any .bak entries) was completely missing. Only the SIDs for the Domain User and Default profile were present.

Even after logging out and back in, the key still hasn't been created, and I'm stuck with a temporary profile. Since the SID key is entirely missing from ProfileList, is there a way to manually recreate this registry key, or is there another recommended way to fix this issue?

Thank you again for your time and support!

Hi Fuma​ ​,

I’m sorry for the delay in replying. 

What is the output when you type the following command in the command line?

whoami /user

 

If you can see a username and SID in the output of this command and share them with me, I think we can create the correct key under ProfileList in the registry.
