I have installed Windows 7 on my computer and it works great. But there is a problem with the XP mode in windows 7. It resets and forgot my login details on my computer. Recently i have removed the password from the virtual computer through control panel and then i enabled the guest account and had used the xp mode from a month with no problems. But there was a day when i tried to bootup, it asked me the login detail which was unexpected, it was always loads up straight to the desktop without asking me the username and password. And also i tried with username Administrator it said that "Your account has been disabled. Please see your system administrator ". I am unable to logon to XP mode. Please help me i don't know what to do..
