It wasn’t too hard to see this one coming, but Microsoft has now officially rolled out the beta version of Windows Home Server Power Pack 3 which, among other things, brings with it a slew of new features that tie into Windows 7. That includes support for full image backup of Windows 7 PCs, Windows 7 libraries support for shared media folders, built-in Windows Search 4, and a number of Windows Media Center enhancements, as well as “better support for netbook computers,” although Microsoft doesn’t seem to have elaborated too much on that. No word on a release date for the non-beta version just yet, but Microsoft is apparently hoping to get it out in advance of Windows 7 — and, yes, it will be a free update for current Windows Home Server users.
