On my company provided laptop, I use Windows 10 64bit as host and run several VMs (Linux and Windows 10). After my vacation, I installed all available updates in my Windows 10 VM and it stopped booting (freezes at black screen with blue logo, no spinner). I thought of a random disk corruption, restored an older version (from backup, not from snapshot) and it booted right up. Installed updates again => same failure. Thus, I don't believe random disk corruption. Trying several tries to use Windows recovery tools didn't work, rolling back helps. I didn't yet investigate the exact Windows Update that caused it since rolling back and re-doing the updates is really time consuming.
The log (attached) indicates an MSR/Microcode-related problem that persists with all tried Acceleration methods:

Regarding the logs: Don't be surprised about the "VM resets" I had to do.... I fiddled with the boot loader / sequence and now the VM takes several tries to actually get to the error
