Yes.  Just fire up regedit and search for gnupg (or maybe just gnu).
There are also the folder / files in:

%ProgramFiles%\GNU\GnuPG

You probably just want to test whether either of these files
are there since them or one of the others is what you are using:

%ProgramFiles%\GNU\GnuPG\pub\gpg.exe
%ProgramFiles%\GNU\GnuPG\pub\gpg2.exe
