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.

action	bytes
original image	40,212,793
set system restore to 1gb max, compressed vhd	14,006,618
ran windows defragmenter, compressed vhd	15,456,481
ran flexomiser defragmenter, compressed vhd	13,903,606

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