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.

  • I receive the same messages on a Windows 2012 virtual server. Annoying as they are flooding the logs. Even with the virtual pointer hardware disabled. – Aaron C. de Bruyn Sep 24 '15 at 15:50
  • Same messages on fresh, fully updated 2012 R2 VM – goofology Jun 29 '16 at 16:15
