Updates available for XP-7 and MS Office. There is also an optional update for Windows 7 that basically prepares your computer for SP1.
This update is necessary to successfully install and to remove any service packs to all versions of Windows 7 and on Windows Server 2008 R2.
FWIW, I have no clue when Windows 7 SP1 will come out. Last I heard was Q1 which means sometime before April.
