Microsoft has announced service packs for Windows 7 and Windows Server 2008 R2, but declined to set a release date or a schedule for getting a beta in users' hands. A company spokesman said Windows 7 Service Pack 1 (SP1) will primarily contain 'minor updates,' including patches and hotfixes 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 Wednesday 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 service packs, saying only that it would provide more information as release milestones approach
