Upgrade Hyper-V 2008 R2 Core with ServicePack 1


Today I wanted to install Windows 2008 R2 SP1 on my Hyper-V 2008 R2 Core machine. This machines boots from a VHD on a Flashdisk. So the amount of free space is limited. I had 8GB of free space. On normal Windows 2008R2 server this amount of free space is enough. On my Hyper-V server I got the error that 10GB of free space was needed. Personally I think that’s a lot of space needed for a SP. My main problem was that getting more free space wasn’t a option. So I searched the Internet and found that the extra space was needed for the installed languages. When you uninstall these packs the amount of needed disk space goes to 7,5GB. For me enough!

So I did the following steps to complete the installation of SP1:

1. Start ‘lpksetup’ to uninstall the additional Languages. I only need the English one so I uninstalled all the other ones. ( Duration: 6 Hours)

2. Start the SP1 installer and install the SP. (Duration: more than 12 hours)

It’s that simple!!
