      Description of problem:

      Applied windows updates from June: KB5060842 and KB5059502.

Post-patching these virtual machines are failing to boot with a BSOD and message of `Unsupported Processor`.

If we modify the VM yaml cpu model from 'host-model' to 'EPYC', the system boots correctly. 

Worker Node has the following cpu model:
`AMD EPYC 7763 64-Core Processor`

This has been seen on Windows 11 and 2025 so far.  Unclear on whether it affects other Windows releases
