Microsoft is moving antivirus providers out of the Windows kernel. Hopefully anti-cheat will be next (www.theverge.com)

Microsoft has long wanted to get vendors out of the kernel. It's a huge privacy/security/stability risk, and causes major issues like the Crowdstrike outage.

Most of those issues also apply to kernel anti-cheat as well, and it's likely that Microsoft will also attempt to move anti-cheat vendors out of kernel space. The biggest gaming issues with steamOS/Linux are kernel anti-cheat not working, so this could be huge for having full compatibility of multiplayer games on Linux.

I don't think chain of trust and security through kernel-level access are fighting the same problem.

Usually chain of trust is to prevent app tampering, and kernel-level access is to prevent memory tampering.

I assume Windows is creating a new API for applications to monitor certain regions of memory for tampering without needing kernel access.

Kernel level access is to stop access plain and simple. That includes user access rights absolutely.

There already is a API for this with ebpf for Windows and it is the same API that can be used on Linux (because it originates from Linux).

EBPF still runs in Kernel space but in a much more limited and confined way.
