Change Name of User Profile Folder in Windows 10  

Shawn,
Thank you, thank you, thank you! For months I've been trying to get this figured out, and it only took a few minutes when following your tutorial! So informative, & instructions are so clear. Amazing!

Great tutorial. Thanks for that. I have a follow-on newbie question. Let's say that I only need to change the ProfileImagePath for a user, who ended up somehow ended up with two folders under C:\users (let's say user.correct and user.incorrect) and got pointed to the user.incorrect folder. Can I just follow steps 1-9, and simply correct the ProfileImagePath to point to c:\Users\user.correct? Would that have the desired effect?

Thanks so much for the quick response!

Shawn, you are a saviour. Very clear and concise. With a little knowledge from DOS days, RegEdit, and a file Commander, I was able to perform the transition from the dumb MS forced user name to my user name on other systems.

Now I can back up, mirror, easily sync, back up/restore from one laptop account to another (via my server). Ran all the programs, had to do some minor changes in pointing to certain files. Again "THANK YOU"! -= Parfumeur =-

I tried your steps, but got some weird behavior. It wouldn't let me log back into my original account. I got a message instead that it was creating a temp account for me. When I went back to the admin account and looked at the registry, my former SID now had ".bak" appended to it. I removed the ".bak" and tried to log in again. Finally, I renamed the user folder to what it had been named just before, and I was able to log in normally.

The user folder name used to be "druek." Then, as described below, it got changed to "Documents," which is confusing. I tried to rename it to "druekberg" following the above instructions. That's when I wasn't able to log in, and was forced to use a Temp account (or Admin). Once I renamed it to "Documents" I was able to log in.

Background:
The original problem started when I was moving some user folders to another partition. I realized the partition drive letter would not work (it was the same as my external backup drive). I moved everything back to C in preparation for renaming the drive letter (so connections to user folders wouldn't get broken). During the move I got a weird message about the Documents folder being merged with the Documents folder that already existed (I thought that meant the one in the user profile and on the partition drive, which contained different subfolders). I said OK and proceeded. All the folders and files were merged.

I can live with this user folder being named "Documents." What's weird is that in Security settings, the folder is still identified as "druek," the original profile name. I'd rather have things be consistent. Plus having a profile named "Documents" is weird, as you can imagine.

I could just start from scratch and revert to the original OS setup, but I'd rather not have to spend hours porting my files over from my old machine. On the other hand, I'm starting to spend hours on this issue. I'm still working on my W7 machine, and trying to set up my new W10 machine. So I can start over if need be.

If you'd like screenshots of the registry entries, I can provide them.

As always, your help is very appreciated.
