Virtual Machines not shutting down on host shutdown in Windows Server 2012 R2

Just wanted to let everyone know of a fix for Hyper-V that was included in the November 2013 update rollup for Windows Server 2012 R2 (

The fix in question ( applies to Hyper-V servers that:

  • Are not part of a cluster
  • Have had the virtual machine automatic stop action changed from save state to shutdown

Without this fix Hyper-V will turn off a virtual machine (instead of cleanly shutting it down) when the physical computer is shutdown.  With this fix the virtual machine will now be shutdown correctly.
