As of Windows Server 2016, the Hyper-V Integration Services installation disk is no longer available.
Indeed, these Hyper-V integration services are now integrated by default in recent versions of Windows (Windows 10 and later) and are then updated automatically via Windows Update.
However, Microsoft provides update KB3071740 for Windows 7, 8 and 8.1 which allows you to manually install these Hyper-V integration services on these older versions of Windows.
Source : Integration components available for virtual machines not connected to Windows Update.
To find out the version of Hyper-V Integration Services currently installed in a virtual machine, open the Windows Registry Editor.
In the registry editor that appears, go to the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtual Machine\Auto" registry key.
In this registry key, you will find an "IntegrationServicesVersion" data which corresponds to the version of the Hyper-V integration services installed.
To download KB3071740 update (corresponding to Hyper-V Integration Services), go to "https://support.microsoft.com/en-us/kb/3071740".
Important : we recommend that you download the update from your Hyper-V server and then transfer it via an SMB share (for example) to avoid problems accessing the Microsoft site.
In our case, we used Windows 8.1 as the guest operating system, because this version of Windows is still supported by Microsoft's site even though Windows 8.1 is not yet updated.
Indeed, as you will see later in this tutorial, if you are using Windows 7 or 8 and it's not up to date, you will see that the Microsoft site will be strangely inaccessible.
The "Hyper-V integration components update for Windows virtual machines ..." page appears.
On this page you will find a table with the download links for this update for Windows 7, 8 and 8.1 (both 32-bit (x86) and 64-bit (x64)).
In our case, we choose the "All supported x64-based versions of Windows 8.1" download.
By default, you will be redirected to the English version of the download page for this update "KB3071740".
If you want to download the update in another language, select the desired language from the list and wait for the page to refresh.
Once the page refreshes, click the download button.
In the case of Windows 8.1 x64, the file to download will be : windows6.2-hypervintegrationservices-x64.cab.
The CAB file has been downloaded.
To install this update downloaded in ".cab" format (and not in ".msu" format), you just need to open a powershell command prompt as an administrator.
Or right click "Command Prompt (admin)" on Windows 8.1 "Start" button.
Type "powershell" (if you opened a "cmd" command prompt instead of powershell).
Then, use the command :
Add-WindowsPackage -Online -PackagePath C:\Users\win8\Downloads\windows6.2-hypervintegrationservices-x64.cab
Wait while installing this Windows package.
Once this update is installed, you will need to restart your virtual machine.
To do this, type "Y".
The virtual machine restarts.
During the restart, you will see the "Installing updates" message appear.
Hyper-V Integration Services have been installed.
To verify that these Hyper-V integration services have been installed (or updated), return to the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtual Machine\Auto" registry key.
As you can see, the value of the "IntegrationServicesVersion" data has changed.
In our case, the version changed from "6.3.9600.16384" to "6.3.9600.17903".
To benefit from all Hyper-V integration services, go to the "File -> Settings" menu of your virtual machine.
As you can see in the "Integration Services" section of your virtual machine settings, by default these are all enabled except one.
To benefit from all integration services, also check the "Guest services" box.
