When I turned on my computer only the Guest account showed up. Before, I had two accounts: 1)Administrator 2) Guest I turned off my computer one day. The next day when I turned on my computer, it only showed one account, Guest. I also did NOT have any internet until now to e-mail you guys. I usually use the internet at the library instead incase of viruses. Thank you!1 person needs an answerI do too

Try to log on in guest account as it only show up and then go to start and log off. See if you can see admin account or not. Some thrid-party software will do this but it also might be Virus infection. If you could run into admin account , the log on to: http://onecare.live.com/site/en-us/default.htm And run full system scan, using Internet Explorer and make sure you allow pop up and Active X when needed.

That didn't work.

Try to contact Microsoft support and discuss issue with them. Also you might try to use Windows CD if you have and use repair option to repair your system. The other option is to use this tools : http://security.symantec.com/nbrt/nbrt.asp?lcid=1033&origin=default And see if you can resolve the problem or not.

The website didnt work cause I am not an aministrator. I am in a limited account.

You should use another PC and then log on to the website and download tools there(NOT in your corrent PC) , then log on to website make a CD/DVD or Removable Device ready to create boot , follow instrution to create boot and then back to your own PC and then boot using device that you use CD/DVD or External Device. I am also suggesting that contact Microsoft Support for help about this.
