Where does one find all the ADMX files for Citrix products these days? I see some on the ISO, but is there a magic link on the Citrix website that i somehow cannot see, that points you to all of them?

depends on the product. The WSA ones are actually in the WSA folder after you install it.

No consistency. UPM seems to be the only one that has them on the ISO, and Citrix website only comes up with workspace app when you search for them. Everything else you seem to have to install, or at the least extract to access them. Not sure why the secrecy..

agreed
