Vista SP2 as guest on HyperV
For those playing with Vista SP2 (why am I doing this??!!) on Hyper-V, and no matter what they do, integration services just don't get installed properly, don't panick...
Pop in the SP2 for Windows 2008, wait damn long (30 min to 1 hour) for the update to complete, then install the new integration services, and you are good to go.
