Microsoft yesterday announced more information about the first service packs they will be releasing for both Windows 7 and Windows Server 2008 R2, but no release dates have been scheduled.

According to a Microsoft spokesman, Windows 7 Service Pack 1 (SP1) will primarily contain “minor updates,” including patches and hot-fixes that will have been delivered earlier via the Windows Update service, rather than new features. One of the latter: an updated Remote Desktop client designed to work with RemoteFX, the new remote-access platform set to debut in SP1 for Windows Server 2008 R2.

Windows Server 2008 R2 will also be upgraded to SP1, Microsoft said, presumably at the same time as Windows 7 since the two operating systems share a single code base. Besides RmoteFX — which Microsoft explained yesterday in an entry on the Windows virtualization team’s blog — Server 2008 R2 will also include a feature dubbed “Dynamic Memory,” which lets IT staff adjust guest virtual machines’ memory on the fly.

Microsoft did not spell out a timetable for the release of the service packs, saying only that it would provide more information as release milestones approach, although it is likely that the service packs will be available the 4 quarter of this year.
