does what Qubes do to Linux and Windows 7, but to Windows 10 on KVM, by using RDP. Not the best approach but no one is working on the Windows 10 port of the windowing thing. Maybe some people could work on porting this to Qubes, and maybe some prople from Qubes could direct funds to this.
I even opened an issue about this:
I miss using Windows properly when I work on Qubes.
Would be nice if people from here could make some noise there to bring attention
