In a Pi 4 it runs relatively well. I've done it both natively and as a KVM.
Check the WoRProject ( https://worproject.com/ ).
A Pi 5 would be even better though there you currently might need to use
KVM as the native drivers are still a work in progress.

It's a Windows specific issue, cause the PE format has slightly different
relocation requirements than the ELF format.
