Solved {URGENT}My only administrator acc is guest account now !

Hello SF members.

I need URGENTLY help !!!
I have one biggest problem ever.

I did this tutorial : Log on Automatically at Startup - Windows 7 Forums !
I yesterday actived auto Log On on my administrator account (I have only this account, and dont have any standard account!).
When I went to sleeping I turned off my computer.

Today, I turned on my computer. It loged on automatically and It worked.
But When I wanted to run one game with Administrator (Run as Admin) it said Error.

I think that is ok , maybe some error in game. I tried to create Homegroup today. I cant. I tried to open Device Manager, error.

I deactivated auto Log On , and I loged off but nothing
That dont work.

I went to Control Panel - User Accounts , and I have a lot of things to see.

My user account is guest now.
Yesterday that was administrator.

I dont have anymore administrators or other users. I have only this user !
I tried System Restore , but I cant run this without Administrator.

Please , help me !

What to do ???

Note : I tried to enable Built-in Admin but access is denied. I dont have Windows 7 Ultimate x64 install DVD. I cant get in or download and burn to CD because I cant burn without Admin. My friend have Windows 7 Ultimate 32-bit if that can help (if you need command promt only.)

Please , help me !!!

Use the link here to burn a DVD for repairs: Clean Reinstall - Factory OEM Windows 7

You can copy out your files using Copy & Paste - in Windows Recovery Console or Paragon rescue CD.

Then boot into DVD System Recovery Options to try Startup Repair a few times, then System Restore.

I dont need anything of this.

I fixed my error easy.
What I did :

1. Restarted computer
2. After POST , press F8 to open Advanced Boot Settings
3. Open Safe Mode
4. My Safe Mode was logged with that guest account so I need to Log Off and then I can log with Administrator account (built-in)
5. I maked new account who have administrator.
6. That is all.

Theard is solved.
Thanks.
