Lost my own account

[somedaysomewhere]

I did this
"control userpasswords2" -- Enter
I chose my current account name "PPP" in the listbox, then Properties; In he General tab's Username, I change "PPP" into Computer, and Apply.

I left my computer free for a while until the screen saver came up and I had to logon again via logon screen, but I couldn't see my account there anymore. Only a new account named Administrator. I remember I never turned on Administrator account.
Ok, I now log on with this Administrator to see what happened but I have no clues at all, because I don't see my PPP account in Control Panel's User Accounts anymore. :cry:
I enter the Document And Settings folder and see the PPP folder but I can't open it.
I have tried to turn off my computer and am reported that there is another account that is being logged on. I realize that "IT IS STILL ALIVE!" but what should I do to bring back my account ? :cry:

Thank you

Please help me quick, I have run my computer for nearly a day or so, I think it needs some rest while I am afraid I won't see the account again if I decide to log off the running hidden account:cry:

Option1:
Since you can log on as Administrator but not as the previous user I would create a new accont with admin priviledges just to be on the safe side and then shut down and reboot the machine. Sure, it will terminate all your open applications but hopefully you don't lose that much.

After the reboot and logging in as admin you hopefully can be able to create a new user account and move your old files to that new user account.

Option2:
Buy a new disk, install that as boot disk and the old one(s) as second/third and so on, reinstall the OS and recreate all accounts you want. When done copy (as admin) your old files to the appropriate place on new disk.

Disclaimer! I haven't got a clue if you succeed or not but those are the only options I can think of and what I would have done. The last time I had a misbehaving machine I bought a new disk and reinstalled the OS and I think it actually saved some time compared to struggling with a lot of other attempts.

Sounds like you may have deleted the account, although I'm not sure what version of Windows you're using, so I can't attempt to replicate.

You can try to "Copy" the profile:

1) Create a new user account.
2) Login as an administrator
3) http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/sysdm_userprofile_copy.mspx?mfr=true

Otherwise, since you can see your "ppp" folder under documents and settings, just take ownership of the folder and pull out what you need:
