Oddly, I am unable to open a downloaded .vss file. from a well known company.
Okay cool.

Uh oh, it's greyed out. Hmm, must be in the registry.
Still, seems silly, if cannot open stencils by default. Are they so malicious?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Visio
HKEY_CURRENT_USER?
Just save to Power Point file or jpeg, I guess.
