Via the Windows Home Server Team:

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!

German, Spanish and French versions will be available on the Download Center the first week of August. Windows Home Server customers who don't download it on their own will receive Power Pack 1 via Windows Update on August 12, and Chinese and Japanese versions will RTM in early 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 improved performance. Documentation for Power Pack 1 is available here.

In conjunction with the release of Power Pack 1, HP will release a software update for the HP MediaSmart Server, delivering enhanced media streaming capabilities from PacketVideo, server-side anti-virus from McAfee and compatibility with 64-bit home PCs.

Windows Home Server can now be purchased in 50 countries worldwide. And a growing ecosystem of third-party software developers have released or announced approximately 60 Add-in programs extending Windows Home Server's capabilities.

We continue to hear fantastic feedback from our customers about how Home Server is helping them protect their digital media, share it with friends and family, and access it from outside of the home. Thank you to our beta testers and partners for helping us ship Power Pack 1, and to the Home Server community as a whole for its ongoing support and enthusiasm.
