In the unlikely event that you decide to uninstall an update after you've
burned the folders to CD and removed the Add/Remove entry, I assume that the
procedure is to copy the $NtUninstallKBxxxxxx$ folder back to C:\Windows and
then run C:\Windows\$NtUninstallKBxxxxxx$\spuninst\spuninst .exe.

Sometimes, there's an spuninst.bat in the ...\spuninst folder (more often
it's spuninst.txt and/or spuninst.inf), but I assume that this is *used* by
spuninst.exe and is not what the user should use.
