Modern kernel anti-cheat systems are, without exaggeration, among the most sophisticated pieces of software running on consumer Windows machines. They operate at the highest privilege level available to software, they intercept kernel callbacks that were designed for legitimate security products, they scan memory structures that most programmers never touch in their entire careers, and they do all of this transparently while a game is running.

It’s only a small annoyance in the grand scheme of the utter idiocy that is modern Windows, but apparently it’s one enough people complained about Microsoft is finally addressing it. In all of its wisdom, Microsoft doesn’t allow you to set the name of your user’s home folder during the installation procedure of Windows 11.
