Microsoft has released the second service pack for its Windows Vista and Server 2008 operating systems.
Vista SP2 and Server 2008 SP2, which pull together various updates to the
operating systems that have already been rolled out by Microsoft in a
piecemeal fashion, were uploaded to Microsoft's Download Center on Tuesday. The
two service packs are combined in a standalone
package that lets system administrators deploy and support both client and
server updates in one operation.
Microsoft has not said precisely when the service packs will be rolled out as
automatic updates, although Microsoft blogger Brandon LeBlanc said in a blog
post on Tuesday that this would happen "sometime during the coming months".
Once the service packs become automatic updates, business customers who want
more time to prepare for the implementation of SP2 can use the same blocking
tool that Microsoft provided for Vista SP1, LeBlanc wrote.
Some of the updates included in SP2 cover third-party application
compatibility, such the new ability for Spysweeper and ZoneAlarm to work with
POP3 e-mail accounts. Microsoft has also included version 4.0 of its Windows
Search technology in the new service pack.
SP2 also adds support for the Bluetooth v2.1 specification, improves
performance for Wi-Fi connections after resuming from sleep mode, and makes it
possible to natively record data to the Blu-Ray optical disk format. The service
pack also adds support for Via's new 64-bit CPUs.
For enterprise customers, SP2 fully integrates Microsoft's Hyper-V
virtualization environment into Server 2008. The service pack also introduces
the ability to manage server and desktop power management settings via group
The standalone installer for both service packs--aimed at system
administrators--weighs in at 390MB for the x86 version, and 622MB for the x64
Those installing SP2 through Windows Update will, however, get away with much
lower data usage, as that service only downloads the bytes that are changed.
Using this method, the x86 versions of Vista SP2 and Server 2008 SP2 will
involve 43MB and 47MB of downloads respectively, and the x64 versions will
involve 60MB and 90MB of downloads respectively.
There are a few prerequisites for the
Vista and Server 2008 SP2, one of which is that the first service packs for
the operating systems must already be installed.
IT managers who publish applications with Citrix XenApp will also need to
install and configure Terminal Services (TS) Licensing before installing Windows
Server 2008 SP2, otherwise their Citrix clients will not be able to connect to
