On July 21, Microsoft announced that the final version of the Power Pack 1 update for Windows Home Server is available for immediate download.
Power Pack 1 is basically a feature pack. It adds 64-bit Vista support, shared-folder backup, remote-access improvements and power-consumption functionality to Windows Home Server. Power Pack 1 also includes a fix to the data-corruption bug that had plagued a number of Home Server customers.
Microsoft decided to delay delivery of Power Pack 1 to include the data-corruption fix, a choice that met with a mixed reception among Home Server users. In mid-May, Microsoft acknowledged it had cut the expected database-backup functionality from Power Pack 1 in order to ship the Power Pack sooner rather than later.
Windows Home Server users who want Power Pack 1 can get it now from the Microsoft Download Center.
