Hi,

If you want to make it fail, then you need a Windows without the Explorer, so either try to kill/disable it, or try on Windows Server Core (without GUI) https://learn.microsoft.com/en-us/wi...top-experience
I love (re)installing these after renting a dedicated server, just removing the GUI and Shell, but it seems Microsoft did removed this feature recently so you can't uninstall/install the GUI any more, shame !

Server 2008/2012 does support this feature unless they ruined it by some update, Server 2016/2019 not sure, the recent ones sure not have the ability to install/uninstall the GUI.
