Tomorrow, Microsoft will release its second functional update to Windows Home Server (WHS, see my review), called Power Pack 2 (PP2). PP2 follows WHS PP1 (see my review), of course, which shipped last July. Like that release, PP2 is a combination of new features as well as the types of bug fixes and other updates that we’ve come to expect from Service Packs (SP2). But unlike PP1, PP2 isn’t a major release. Instead, it focuses on a few key improvements. I’ve been testing various versions of PP2 since late 2008 on my product home server, and it’s a testament to this release that it’s never caused any issues at all.
