Microsoft has pushed out its first patch for the Windows 7 public beta. The update saves your MP3s from a rather nasty bug that trims seconds off any song that's been edited, either by you or via automatic updates from Windows Media Player. If you've got afflicted files, there's a chance they're salvageable via properties window, according to the patch notes -- and if not, then here's hoping you backed up your library. Additionally, a new update has gone out to Windows 2000, XP, Vista, and Server 2003 / 2008 that fixes some vulnerabilities in the Server Message Block (SMB) protocol. Beta users won't get their fix until the next public release, explains Microsoft Security Response Team's Christopher Budd, since it's only considered a "moderate" risk for the new OS.
