STOP C000021 - Windows Logon System Process terminated unexpectedly

Dell Latitude C640 with Windows XP Pro sp2 with all current updates. I run
"Windows Updates" religiously. Guess that was a mistake :) The laptop will
not boot past the logon screen. The logon screen comes up and then quickly
disappears, causing a BSOD:
STOP C000021 Windows Logon System Process terminated unexpectedly with a
status of 0xc0000005 (0x00000000 0x00000000).

I have read that this may have something to do with recent security KB
updates: 893066, 890923, 8908059, 893096.

This should start to become a common problem so hopefully we'll see some
posts soon. Wondering if home users should turn off Windows Automatic
Updates !

Here is a suggested fix from a Google search. Sorry, can't remember the URl
where I found it.

1. Insert the Windows XP sp2 startup disk in your floppy disk drive or
insert the Windows XP CD in the CD drive or in the DVD drive, and then
restart your computer. Press any key to boot from CD. Note: Your computer
must be configured to start from the CD drive or the DVD drive. For more
information about how to configure your computer to start from the CD drive
or the DVD drive, see the documentation that came with your computer or
contact the computer manufacturer.

2. When you receive the Welcome to Setup message, press R to start the
Recovery Console.
Note: Multiple options will appear on the screen.

3. Select the Windows XP installation in question.
Note You must select a number before you press ENTER, or the computer will
restart. Typically, only the 1: C:\Windows selection is available.

4. If you are prompted to type an administrator password, do so. If you do
not know the administrator password, press ENTER. (Typically, the password
is blank.)
Note You will not be able to continue if you do not have the administrator
password.

5. At the command prompt, type cd $ntuninstallKB number of patch$\spuninst,
and then press ENTER.
Note After you complete this step, you cannot stop the removal process.

6. At the command prompt, type batch spuninst.txt, and then press ENTER.

7. After the Patch is removed, type exit, and then press ENTER to Uninstall
the Next
