Our client had thin clients that where managed via a controller over pxe. We replaced the hyperv with vm’s in the cloud and they didn’t want to buy new PCs. So we got them small SSDs instead and I set up a debian image with autologin and a script that asks for credentials to launch xfreerdp in fullscreen. It worked great (until they finally got new hardware).

I can give you some of the code next week if you want.
