Ouch! – Hyper-V Server R2 Needs 10GB of Free Space for SP1

Here are a couple of observations when installing the new RC for Windows Server 2008 R2/Hyper-V Server R2 SP1.

I know 10GB of free space is not what is used to be, but it is still a lot for working space to perform an install.


It is also a bit interesting that the installer recognizes the system correctly as running Hyper-V Server, but presents a link to “Go online for other options.”


On the flipside if you are running the full version of Windows Server 2008 R2 you do not seem to need 10GB at all.


Bug? Design Difference?  Anyone know?

    It’s due to how the multi-lingual capability is implemented. Since we included language packs by default, the installer needs more space. If you remove the language packs using dism.exe (as detailed at http://technet.microsoft.com/en-us/library/dd799306(WS.10).aspx), the 10 GB space requirement will disappear.

    If you install additional language packs in Windows Server 2008 R2, you should see the same behaviour.
