Monday that Windows 7 Service Pack 1 is available in public beta form. While desktop Windows 7 is looking mainly like a rollup of hotfixes, the update for Server 2008 R2 is more substantive. Server will be getting the new RemoteFX feature which will provide higher quality 3D accelerated graphics for remote users. Server 2008 R2 is also seeing dynamic memory support added.
A copy of SP1 leaked online back and April and is rumored to have USB 3.0 support and an updated Bluetooth/Wi-Fi stack. None of this has been confirmed yet, but the update isn't final yet. To try the new service pack, you have to pretend to be either a developer, or an IT professional. You'll also need a final copy of Windows 7 or Server 2008 R2. Download it here . Let us know if you give it a shot.
