Hyper-V VMGuest.iso for older Windows OSes in Win10/2016

Posted by essjae on March 2, 2017

If you’re playing around with older OSes in the latest versions of Hyper-V, you’re missing one thing, the Integration Components (IC).

With Win10/Server2016 they no longer include this ISO as the current “supported” OSes all get their IC viaWindows Update.

You can get the IC from Hyper-V 2012/2012R2 Server, a free download, here:

https://www.microsoft.com/en-us/evalcenter/evaluate-hyper-v-server-2012-r2 ( to extract, you’ll need to mount the ISO, open the x:\sources\install.wim file with something like 7zip, browse to Windows\system32, and extract the vmguest.iso or install Hyper-V Server in a VM to get the vmguest.iso)

Or, if you’ve got a Windows 8/8.1/2012/2012R2 VM/system available with Hyper-V installed you’ll find it in the C:\windows\system32\ folder.

I’ve got a copy from Hyper-V 2012 R2 here: https://1drv.ms/u/s!AnbqFQxI6C6pibttEpT9LXnRf4jcYg 

Hyper-V 2008 R2 here: https://1drv.ms/u/s!AnbqFQxI6C6pio4TpkS4Yi9Pl0_Ejg 

Hyper-V 2008 here: https://1drv.ms/u/s!AnbqFQxI6C6pio4UYt3Jn_VLbrQs4w

No guarantees how long MS will allow it will stay up here, though it’s freely distributed with Hyper-V Server.

After installing the IC on OSes older than Windows Server 2012R2,  you will still see 2 unknown devices.  Per Microsoft, this is expected: https://support.microsoft.com/en-us/help/2925727/unknown-device-vmbus-in-device-manager-in-virtual-machine-for-avma

If you view the properties of these devices and check driver details, Hardware IDs or Compatible IDs, they will show the following:

  • vmbus\{4487b255-b88c-403f-bb51-d1f69cf17f87}
  • vmbus\{3375baf4-9e15-4b30-b765-67acb10d607b}
  • vmbus\{99221fa0-24ad-11e2-be98-001aa01bbf6e}
  • vmbus\{f8e65716-3cb3-4a06-9a60-1889c5cccab5}

These Virtual Devices (VDev) are provided for Automatic Virtual Machine Activation (AVMA) to communicate with the host. AVMA is only supported on virtual machines running Windows Server 2012 R2 or later versions of operating systems.

Windows XP Pro running in Hyper-V. Device Manager shows the 2 unknown devices after the IC have been installed.

Update:  The Integration Components won’t install in the Home and Starter versions of Windows.
