Use the hidden account named 'Administrator' to log on and then one at time
uninstall each update till you find the culprit. You could also create a new
account to see if the problem persist.

For XP Home users:
Boot the computer into Safe Mode
Do this by pressing the F8 key after the Power On Self Test is finished,
until the Start menu appears.
This will get you to the correct menu window.
Once in Safe Mode, you will see the normally hidden Administrator account
and any other accounts.
(Note: Accounts are displayed alphabetically).
Use the Up/down arrow keys to highlight the 'Administrator' account;
Remember as mentioned above: The default password is a blank (no password
required).

For XP Pro users:
You do not need to go into Safe Mode.
At the Welcome Screen, do/press the Ctrl-Alt-Del keys twice to display the
Windows logon box.
Type in "Administrator" (without the quotes) and 'if' you assigned a
password when you set up Windows, then enter it. (Note: by default the
password is blank, no password need be entered)
