We may be able to run most Windows console apps interoperating with Cygwin console apps, but with some Windows GUI apps about all we may be able to do is launch them with cygstart: trying to integrate a security related app based on an old release of an app designed for another platform offers too many opportunities for mismatches. As the OP has Debian TBB and dirmngr, why not use them, maybe from Cygwin/X? Or the OP could install and run GNU PG/2 for Windows with TBB for Windows so the apps would be working on the same basis and making the same assumptions about paths, certs, IPC, perms, and errors. Alternatively the OP could try building the Tor Browser from source to run under Cygwin/X for use with Cygwin dirmngr, although as Tor is based on (old) Firefox, and that is not available under Cygwin/X, and available browsers tend to be lightweights, there may be too many porting issues from embedded Unix and Windows assumptions to make that feasible, as I'm sure someone has (or maybe a few have) tried that. -- Take care.
