no admin access, non of the tricks working!

[eadweard]

I have managed to lose access to admin account and non of the tricks to get it back will work for me.

So here's the stupid thing i did to cause this:

My folks have a new dell lappy. The first admin account I set up for them. I created a second admin account for myself which I wanted hidden (ctrl alt del at welcome screen).

So in 1 session, I enabled ctrl alt del through netplwiz; edited the registry to make my admin account hidden, and lowered my folks account to standard user.

After restart, ctrl alt del wont work at welcome screen so i cannot access admin account.

I have tried running command prompt as admin and activating administrator account but i get 'type 5' error.
I cannot run gpedit.msc, get a not found error
I cannot make any changes in safe mode that a standard user cannot make.

so feel free to call me a muppet or whatever, but please help, there must b a way without having to recover back to factory settings

First try System Restore to before you messed up your parents computer.

If this fails to restore things as they were, Enable the Hidden Adminstrator account, then in User Accounts Manage Another Account, delete the account you set up, set up another as Admin, or restore your parent's account to Admin. Enable the (Hidden) Administrator Account on Windows 7 or Vista - How-To Geek.url

Win7 does not tolerate tweaking beyond normal system settings - it is already perfectly optimized as lean as can be.

Sounds remarkably similar to the above post. Perhaps following some of the suggestions given there will work for you. The link in #9 by Windows sniper sound most promising.

On the other hand, you might just have meant:
