You cannot log on to Windows XP after you remove Wsaupdater.exe

--or--

The problem may be an incorrect system drive letter. With a networked
machine, open the registry and connect to the problematic machine
registry and navigate to:

[MACHINE_NAME\HKLM\SYSTEM\MountedDevices]

and delete all values that look like this:

\DosDevices\C
\DosDevices\D
\DosDevices\E
and so on

When finished, make sure you disconnect the machine from the registry.
There are other ways to gain access to the registry if you cannot
connect to the problematic machine via networked Registry. Please let
me know if you need more information on how to gain access to the
Registry if you cannot by a networked registry.

Addendum:

If you don't have network access to your system/registry, you may use Bart's PE boot CD.
