So after pondering this for a few days, why wouldn't the "easiest" anti-cheat, be to a) have windows attest to the servers that its running in "secure" mode b) have windows provide the ability to apps/games to run in a validated / secure mode, where the OS would not let things like debuggers and the like attach to the game, as well as validate the game executables and assets that are loaded. i.e. part of "A" would be attesting that the executable it loaded had a specific signature and the game itself would then test the signature of all the assets they load.
