In three days Windows 7 Service Pack 1 (SP1) will be released to the general public. As of Tuesday, Windows 7 SP1 will show up as an option in the Windows Update service.
For the most part, there is no need to rush to apply the service pack. There is nothing revolutionary about it, and applying it won’t modify or add any critical functionality. As with any service pack, Windows 7 SP1 includes all of the patches, updates, and hotfixes that have been released for Windows 7 up to now.
The biggest changes in Windows 7 SP1 are an update to the Remote Desktop client to work with RemoteFX–a new feature introduced in Windows Server 2008 R2 SP1. RemoteFX improves the graphics performance of Windows 7 virtual machines hosted on Windows Server 2008 R2 SP1 systems. Windows 7 SP1 also adds support for Dynamic Memory, a feature in Windows Server 2008 R2 SP1 that enables IT admins to adjust the memory on guest virtual machines on the fly.
There are also minor improvements such as fixes for bugs in HDMI audio performance, and XPS document rendering, as well as better support for third-party federation services.
While there is nothing Earth-shattering about Windows 7 SP1, you should still download and apply it. Check Windows Update on Tuesday to get the Windows 7 SP1 update.
