Hyper-V : VHD size optimization

I previously blogged about compressing Hyper-V VHD images as they can 'bloat' and eat disk space. Unhappy with the results, I set about trying to squeeze one of my images more...

The following was performed with a VHD of Vista Ultimate with VS2008 & Office 2007 installed.

ran flexomiser defragmenter, compressed vhd13,903,606


Well worth reviewing VHD file sizes periodically I think...
