Actually, I can't think of any good reason. So we'll likely end up
using the path as-is.

That's what I discovered, too.

According to MSDN, the process-wide AppUserModelID is not supposed to
change (so we can probably get away with pretending that it never
does), but I didn't test what happens if you try on windows. However,
the (not yet implemented) window-wide AppUserModelID can change at any
time (and Win7 picks it up correctly). Maybe invent a window message
for this?
