The team is pleased to announce that Windows Home Server Power Pack 1 has been released to manufacturing (RTM) and is now available on the Microsoft Download Center!
The English version is available now and German, Spanish and French versions will be available on the Download Center soon. Windows Home Server customers who don’t download it on their own will receive Power Pack 1 via Windows Update in August, and the new Chinese and Japanese versions will RTM in August, too.
As many know, Power Pack 1 provides a range of new enhancements, including support for home computers running Windows Vista x64 editions, backup of home server Shared Folders, improvements to remote access, more efficient power consumption and better performance. And, of course, it delivers a fix for the data corruption bug. Documentation for Power Pack 1 (Build #1800, to those who have been part of the beta testing) is available here.
