"Beginning Thursday Dec. 4th, we will be making the Windows Vista and Windows Server 2008 Service Pack 2 Beta available to everyone through a Customer Preview Program (CPP). The CPP will launch on TechNet and be available to anyone interested in trying out this service pack. The CPP is intended for technology enthusiasts, developers, and IT Pros who would like to test Service Pack 2 in their environments and with their applications prior to final release. For most customers, our best advice would be to wait until the final release prior to installing this service pack.

For those of you who choose to test this service pack, we encourage you to install the beta as soon as you can; your feedback will help us to ship a solid and stable service pack for Windows Vista."
