With the closing of the Code2Fame Challenge for Windows Home Server, the Connect site has been updated so that beta participants can no longer download the Release Candidate (RC) version of the software. Beta testers will be able to continue to use the beta product keys they downloaded from the Connect site, but we will not be issuing any more product keys for the RC software.
The System Builder version of Windows Home Server is already available in some countries, with additional countries expected to come online in the coming weeks. Additionally, a 120-day Evaluation Edition will be orderable from the Windows Home Server product pages for a cost recovery basis to cover shipping and handling in the next 4-6 weeks.
In the future, the Windows Home Server team will continue to use the Connect site for interacting with the Windows Home Server community by releasing additional items that we want people to get an early look at. All of the suggestions submitted by the community will continue to exist, as we are busy digging through all of the great ideas as we start planning the next release of Windows Home Server.
However, you can check back Windows Home Server Connect site from time to time to see if there is additional stuff to download and test.Microsoft, Windows Home Server, Beta Testers
