File associations lost!

I am with a user whose PC has lost all file associations, tho' it seems
to be able to start and run certain things (IExplorer for instance).
I have various .reg patches to apply (from www.dougknox.com) but since
the PC doesn't even know how to open Regedit I am stuck.

Doug suggested renaming regedit.exe to a .com .scr etc. but none of
those are recognised extensions either!

Can anyone suggest a way I can break this loop so I can apply a patch?

Thanks
Nigel

Nigel,

If all of the major file type associations are lost, then you may need a
repair installation. Alternately, you can load the SOFTWARE hive of the
current Windows installation, by slaving the drive to another system, or
from a parallel installation of Windows XP.

Load a hive into the registry:
