Honestly, I dont know why "xbox mode" isn't this for PCs. Instead of anticheat, reboot into a stripped down mode just for playing the game that has a secure boot chain that the app can attest and report to the servers about and then reboot back into normal windows.

booting is so quick today that its hardly a friction point as it used to be.

It's called rebooting into rootkitted winblows

This is where we're heading. But just like anything else, there will be an equal and oppsite reaction. Either side of the aisle making one large leap is bad. Regular users lose at every turn.
