The Windows Home Server Team announced on their blog the availability of the Power Pack 1 for that OS on the Microsoft Download Center. Additionally the patch has been released to manufacturing and is expected to become available through Windows Update beginning next month.
With its relatively short life, Windows Home Server has got a mildly positive reception, though it has been limited to a small number of OEM systems and Microsoft hardcore users willing to experiment with it for the most part. WHS is designed to sit in the middle of multiple connected PCs within a household to offer file sharing, automated backups, and remote access.
Much like its Service Pack counterparts, the Power Pack 1 provides a number of enhancements and fixes 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. The biggest fix corresponds to a well documented data corruption bug on Home Server systems that contain more than one hard drive.
