Hyper-V Program Manager
Yay! - We have new Virtual Machine Additions up for the Windows Vista CTP releases. These new Additions (13.709) have performance optimizations for Windows Vista Beta 2 (Build 5384), Windows Vista Beta 2 June Refresh (Build 5465) and Windows Vista Beta 2 July Refresh (Build 5472).
You can download the Additions from the Virtual Server 2005 R2 SP1 Beta program at http://connect.microsoft.com. And for Virtual PC users - do not worry - the Additions are available as a separate download on the beta program, so once you have signed up you can download just the Additions and use them with Virtual PC.
