I installed it.

I started Emacs -Q. I see the emacs.exe process in Process Explorer,
but I don't see any usp10, and I don't see any Uniscribe.  The only
processes listed whose names begin with "u" are unsecapp.exe and
UdaterUI.exe (McAfee).

I tried Show Process Tree, but didn't see anything there either.

I tried Find > Process Explorer Search > Handle or DLL substring,
but that also did not find ups10 or uniscribe or Uniscribe. Perhaps
it has another name?

See attached. #2 is shown after I click No in #1.
