There appears to be a problem with the Synpatics touchpad driver on many
laptops. My install hangs with high CPU use ~70% by the SynTPenh.exe
driver. Others have noted the same behavior. Here's how I got the update
to work on Win2K sp4.
Download the update directly from the microsoft site here:
http://www.microsoft.com/technet/sec.../ms05-050.mspx
I ran the update, had it stall as usual, then went to task manager, verifed
that the above mentioned driver was using up lots of CPU time, then ended
the process. The update then continued to proceed on its own without a
hitch.
A followup check of windows update verifies that the install went correctly
and requires no more updates.
