That's atrocious. Looks like microsoft doesn't care about AMD CPU as much as AMD doesn't care about windows.

As far as I can see there is no easy way to use MSR on windows.

I may be missing something, but since it basically exploits AVX that is easy to disable in win10.

bcdedit /set xsavedisable 1

and then reboot.

At least it fails the zenbleed POC.
