Increasing size of VHD

It happened to me more than once that I've started VPC and only when almost done installing and cofiguring it, I found out that the initial size of the VHD is simply not enough. Well, there's a way to fix that!

You need VhdResizer tool to create a larger copy of the "small" disk. Then you attach that copy to the existing VPC as 2nd drive and extend the volume once booted up.

Very nice detailed how-to is here.
