For when you get your account thing sorted out:
Start --> Control Panel --> Security Center --> Automatic Updates --> Click Download Updates for me, but let me choose when to install them
(Assuming you're running XP)
As for your account issue, I've had corrupted profiles in the past, and the only easy solution I saw was to delete the profile and start fresh. You can still access the files that were in your old profile in c:\documents and settings\<username>, but you won't be able to log in as that user.
