Windows 10: Registry edit mistake. Am I screwed?

I wanted to change my username because I wanted a different username in the filepath, so I did it from the control panel, originally. However, my old username was still being shown in the filepath, and I read that I could change that with the Registry Editor. I did that in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current Version\Profile List. Once I changed the username to the new username I wanted, I restarted the computer, and now, instead of having a different username, I have an entirely new account. No, I did not make any back ups or saves. Is there any way I can get back my old account? In the file explorer, I can see my old account and all of the files associated with it, but I want to actually log into that account again. Is this possible?

Hi Chris,

Method 1: Disable Display Power Saving Technology.

Right-click on an empty space on the desktop > Graphics Properties >

Display Power Saving Technology and see if this helps.

Note: Restart your computer once for the changes to take effect and check for the issue.

We know that you have changed the registry value, but try the below steps and change the value of FeatureTestControl to 9250 and leave it in base hexadecimal.
