How do I know my Server 2003 with RC0 or RC1 of Hyper-V?

I had server 2008 RC0 of Hyper-V, after I installed update which told me that update, KB950049, from RC0 to RC1. But how do I check it that I am runing RC0 or RC1? Thanks

I think if I remember correctly you can see that information in the System Overview applet within Control Panel.


Hi Tigermatt,
There is System  applet but System Overview within Control Panel. Even I checked at System applet, but it does not show RC0 or RC1.

1. locate the VMMS.exe in the path of %systemroot%\system32
2. Right-Click on the VMMS.exe file and select "Properties"
3. Select "Detail" Tab
4. Check the "Product version"


Product version: 6.0.6001.17101                Hyper-v beta
Product version: 6.0.6001.18004                Hyper-V RC0

hope it helps.

Hi LegendZM,
I guess that so. Because before I update patch KB950049, whenever I turn on Server 2008, Release Candidate 0 displays during booting. But now after I update that patch, RC0 didnot appear but neither does RC1. That is why I want to make sure I am in RC1.  I will check VMMS.exe and let you know later.

Ok, then you are definitely running RC1.

Then you're using RC1 :)

I have check vmms.exe, it shows product version is 6.0.6001.18010. Is this RC1?

Yes, that is RC1 :)

Hi LegendZM,
Thank you for your help. I also have other question, ID: 23439360 , about export/import VM from Hyper-V to another Hyper-V, which you are helping me know. Can you please check and help me again?
I really appreciate.
