Identifying your Hyper-V Version

Identifying your Hyper-V Version

Microsoft’s Hyper-V virtualization was officially RTMed on June 26th, 2008. However, there were several early releases of Hyper-V that made their way into a number of Windows Server 2008 installation since Windows Server 2008 was released back in February 27th, 2008. The original Windows Server 2008 release included a beta version of Hyper-V. Since that time Microsoft release two additional Hyper-V Release Candidates (RC0 and RC1) before the RTM date.

So how do you know which version of Hyper-V you’re running?
The RTM release of Hyper is version number 6.0.6001.18016.

If you’re running Hyper-V on the full version of Windows Server 2008 you can open the Hyper-V manager then select the Help, About Hyper-V Manger. The version number 6.0.6001.18016 should be displayed in the About Hyper-V Manager dialog as you can see in the following Figure.

If you’re running Hyper-V on Server Core (or just prefer the command line method of doing things) then you can run the following command:

C:>wmic datafile where name="c:\windows\system32\vmms.exe" get version

If you’ve got the current version of Hyper-V then you’ll see the following output:
Version
6.0.6001.18016
