Iâve written a script to do that automatically.  (Attached.)

It takes the raw list parsed from installed.db using the scheme above and a copy of the setup.ini file downloaded by setup.exe and removes all ânon-rootâ packages, being those that will be installed indirectly by some other package on that list.

It cut my largest local Cygwin installationâs package list down to about a fifth the size spewed out by the command above.

Enjoy!
