You attempted to change the user's folder name and essentially toasted (broke) that account. Next time create a new account with the name you want and move to the new account. Nothing's busted here. That is, renaming the user's home folder in C:\Users is not something anyone should do. Unless they were trying it out to see how to break the system.

I was following these article to do so:
http://social.technet.microsoft.com/wiki/contents/articles/19834.how-to-rename-a-windows-7-user-account-and-related-profile-folder.aspx
Details of my laptop:-
Operating system: Windows
Windows version: 7
Bit: 32
At Step 3, I failed to create a temporary user with administrator privileges through Command Prompt. So, I created it manually through Control Panel with the same exact name and password as instructed.
Then, I proceeded on...
Until Step 6 onwards, problems arise. I changed the username to Default. Step (c) I failed to access the Advanced user management, so I skipped it until Step 7. I also changed the folder's name to Default but it says that there is already a folder named Default existed and asked me if I want to replace.
I then immediately tried to go back to Step 6 and rename it to previous name but failed, so I clicked "Yes" to merge folder and replace the existed folder. At this moment, the only Users folder window frozen. I then realised it happens when I attempted to replace after many times trying.
Also, at the end, I successfully changed back all the names to how previously it was named in Step 6 and Step 7 but I still stuck at user login "Welcome" forever when trying to login to the account I made changes.
Although I made a system restore before doing all these as a precaution, but I fail to restore since only administrators can do restoration. ![]()
