There is a game I am considering getting; it has been out for a few months now, and the devs are specifically blocking it from running under proton with a Kernel Level Anticheat which specifically blocks linux.

Folks on the discussion boards made the point tht it is technically possible to install windows for just one steam game, so I am looking for a guide on how to do that?

I've heard that if you don't activate windows, you can still use it, and if you get the LSTC (?) Version of windows, it is not so annoying.

Does anyone have a guide for how to install windows alongside linux for one game?

If we have a discussion in the comments about whether it is tactically appropriate to give money to a game corporation that requires windows, i guess we can, but i would rather learn how to install windows in the least annoying way possible.
