Windows 7 administrator user corrupted

[shamir]

Hello,

I got a new computer last week and it was working fine up until now running windows 7 professional 64bit.
I activated the guest account and logged on to it, and when I tried to log back to the administrator ("owner") account, I got the following message (on the windows logon screen):

The User Profile Service service failed the logon
User profile cannot be loaded

Now i'm stuck on the guest account which has no privileges...
I think that just before I switched to my guest account a windows update was downloaded but i'm not sure if it was installed or not.

in addition I check the users folder from the guest account and the "owner" user seems to be empty (size 0KB) but when i run the widows essentials scan it on, it seems to be full as there are many files scanned.

I tried to shut down and restart my computer, nothing seems to work, and even when I try to access the user accounts properties with the guest account, i have to enter the administrator password, and it still can't identify the admin user...

I would realy appreciate some help!!!

thanks,

Ilan

and how can i change the admin password or create a new user using the boot cd?

Run msconfig w/ Admin privileges:

Start => Standard => Command Prompt => Right-Click => Run as admin = > msconfig

or => control userpasswords2

OK I FINALLY SOLVED THE PROBLEM.

I used the windows cd to boot and restore the system to an earlier time, but first I found out in the bios that the usb keyboard was not enabled, so when i first tried to boot through the cd i had a problem since it asks if i want to boot through the cd i should press any key, and i wasn't able to do that since the keyboard didn't work.

I also used a regular usb keyboard and not my cordless one (the cordless keyboard still doesn't work at startup even though it is usb, any idea why?).

so lastly: how can I activate the guest account without the same bug happening again? should I create another administrator account just in case?

Nice trouble-shooting, thank you for your feedback!

1. Make sure your admin account does NOT require password. Log off and then in several times to be sure.
2. Control Panel => User Accounts => Manage another account => Turn on Guest

That's it, at system start, it should let you choose which one you wish to log in.
