Tinkering with profiles and registry

Hello,

I have decided to merge my Windows backup with a newer Version of my user profile folder. Now Windows tells me that the user couldn't be logged in. This profile folder also went through a USMT migration in the interim so the SID has changed. So I guess that that is the reason.

My questions are.
Am I on the right track?
Is the SID set in the User Hive also? I only know of this list here: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion \ProfileList
Where would those places be and if it is in binary what software could I use to edit this?

I know many people would regard this as useless effort but I try to see what is manually doable to this OS.

As I said mentioned I have this old backup and I also took a recent image of the whole partition.

Does that mean no one here is willing to give me any hints?

Why not,

Thank you. :)
But I think the only thing that is advisable in this article for me, is just creating a new profile. But my aim is to actually fully transfer that existing one. However I'll check later if the State was set correctly the Path was. I can remember that.

It is exactly the same method except that you will copy your old Profile instead, I use this trick to recover my profile from Windows.old and it works every time. you can even use it to copy you profile from a machine to another one.

First you must create a new profile with the exact same name and proceed to swap it with your old one.

Okay I tried to change the Status to 0 but that just resulted in a BSOD for the dxgkrnl.sys and a repairloop with Errorcode 0x51a for the LCU inside the SrT log.
So I changed that back to 256 and it worked with the before error again.
Now I'll try to search for the SID inside the NTUser hive.

Did you also copy everything like the NTUSER.DAT?

Yes everything, I don't understand how It would have caused trouble with DirectX...
