2012 R2 as a Hyper-V host only
Last night this machine began running very slowly. I shut down the VM's and then the host. That also took forever.
When I restarted the vm host machine it operated properly. When I checked the vm host events I found these errors had occurred prior to the slowdown. The sequence showed twice.
Event ID 265, Source Win32K, A pointer device did not report a valid unit of angular measurement Event ID 257, Source Win32K, A pointer device reported a bad angular physical range Event ID 258, Source Win32K, A pointer device reported a bad angular logical range
I'm not really finding any Microsoft pages that explain these errors and what needs to be done, if anything.
When I reboot this server these same errors show up twice again, a few minutes after booting up.
I wondered if anyone has some guidance regarding this set of errors.
