I went to the control panel to change the password.
It first began with the "Windows cannot change the password error", even though the password still changed on my account.
A few days later, my computer started bringing up the "Windows Security" menu when I hit Ctrl alt delete. The computer also wouldn't let me switch user. I knew how to enable switch user, but it gave me the "Windows cannot apply the Fast User Switching Setting you selected".
Is there a registry fix or something that might fix this. Or might there be some malware? I think it might be malware because even after restoring a backup of my computer the problem disappeared and returned after about a day or two.
Thanks in advance for any help
Edit: I guess it's actually two problems, but I do think they are very closely related.
Edit: I also got my computer off of ebay with a memorex cd labeled "Windows XP Professional", so I don't know if that would make my installation of windows corrupt (which it probably isn't) but I might as well add.
