I suppose one plausible way would be to copy the actual installation and the configuration file for setup.exe that records what has been installed, if there isn't a cleaner way to do it, but I don't know what configuration information would need to be copied for this to work - and I'd assume there has to be a better way, doesn't there? Alternately, the Google search I tried found suggestions to just copy the installation itself, which obviously will prevent setup.exe from later updating it because the information about what's installed will change. The two ways that I know of are to copy the directory of downloaded installation packages from the first computer and do an "install from disk" on the second, selecting everything - but that will include packages that were installed and later removed, as well as what is currently installed. How can I do this in a way that doesn't involve manually going through the list of installed packages on the first computer and entering it in the installation checkboxes on the second? I'd like to duplicate this installation on a second computer, with the same set of packages installed. I have a computer that has a Cygwin installation that has been customized over the years by installing additional packages as needed using Cygwin's setup program.
