[Windows Server 2025 Host] KB5062553 (and June’s) Breaks GPU-P to Windows 11 VM

Here's an off-roading solution: replace dxgkrnl.sys with an earlier version. The problematic version is 10.0.26100.4652. I started a new VM and updated it to 2025-03 and I copied dxgkrnl.sys (v. 10.0.26100.3912) to a VM that was not working and it booted without issue. See below for the now working vm with 2025-07 installed. Since this problem is related to dxgkrnl, it will probably be up to GPU manufacturers to update drivers. This solution is likely very unstable. The preferred approach would be to update a VM to 2025-04 and disable updates until Microsoft or Nvidia fix the problem.
