Capturing a Cygwin instance from another PC

[Andrew Schulman]

> I have a new Win11 PC, and I wanted to capture the same Cygwin setup that I have in another Win10 PC. I copied the C:\cygwin64 folder from the Win10 pc to the Win11 pc, then I downloaded a fresh setup-x86_64.exe from cygwin.com to the win11 PC. I ran it and chose "Install from Local Directory" and only one shortcut for "Cygwin64 Terminal" was created on the desktop. No Cygwin nor Cygwin-X folders were created on the Start menu. The original cygwin from the Win10 PC had X installed also.

> Any idea how to get this done automatically? I know I can go and create folders manually, etc., but it kind of a pain. Any help would be greatly appreciated. Thanks.
