Wow you saved me from so much 'update' distress. Indeed I had done a similar thing somewhere in my distant memory. Simply deleting my hacked registry key entry as shown below solved my problem.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,2a,00,3a,00,00,00,00,00,00

Good tips in this thread. It ultimately led me to my solution. The problem computer here was also running a version of Windows XP modified with NLite.

I was able to resolve this problem by first opening the faulty keyboard log. On the problem computer, it was located in C:\Windows\system32\faultykeyboardlog.log.

The faultykeyboard.log file simply listed these four items:
KBDDV.DLL
KBDUSX.DLL
KBDUSL.DLL
KBDUSR.DLL

I went to a computer that I knew had an unmodified version of Windows XP Professional, copied those four DLL files from C:\Windows\system32. I then transfered them to the C:\Windows\system32 on the problem computer and re-ran the manual installation file for KB2686509 which can be downloaded at http://www.microsoft.com/en-us/download/details.aspx?id=29804.

Problem solved.
