Except for the Adobe PDF printer, all printers from this computer (a laptop)
are attached to another computer and network accessed. FOr the first time
(at least in a long time), when I have attempted to print this evening, my
printers are unable to be found by the programs I use.

I went to investigate this by going to my "Printers and Faxes" folder with
the intent of uninstalling, then reinstalling one or more printers. However,
whenever I attempt to access the "Printers and Faxes" folder, I receive the
message that Data Execution Prevention has closed Windows Explorer in order
to protect my computer.

I looked at my restore point options to see if any updates are to blame, and
the only thing that I see on there that may be the suspect (i.e., the only
thing added in the last day) is a Software Distribution Service 3.0 update.
Before restoring my computer to offset this update and see if it is to blame,
I wanted to see if there are any other ideas out there - or others are
experiencing problems with this particular Windows update?

Thanks,
Zakhary
