Cygwin is a portable application. WinGet is acting as the installer in this case, and depending on whether the package is installed in "user" scope or "machine" scope, or whether the device has developer mode enabled, the installation location will vary.

I was wrong. I just took a peek at the manifest to double check. It's an .exe based installer.
