When I go to Printers and Faxes I get an error about the
Spooler SubSystem App has encountered an error and
must close...

I'm unable to add any printers or delete any existing printers
(only one listed at the moment - a network printer if that is
important)

If I restart the Print spooler service it doesn't stay started.
The following kb article 324757 doesn't not resolve the
issue. I did notice there were two Windows NT x86
registry keys found here:
HKLM\System\CurrentControlSet\Control\Print\Enviro nments\

Why are there two?

There are no Drivers key found below Windows NT x86.

How can I solve this issue of Spooler SubSytem App error?

Thanks.

This did not help.

FWIW, a repair install fixed the issue. Sure would like
to know if there is some other way to solve it.
