For those of you who use the Windows Service Pack Blocker Tool, we want to let you know that the Windows Vista SP2 and Windows Server 2008 SP2 blockers will expire on August 24th 2010. After the expiration date, Windows Vista SP2 and Windows Server 2008 SP2 will be offered through Windows Update on computers that had previously installed the block.
What is the blocker tool? The Service Pack Blocker Tool is provided for corporate customers and IT administrators. It is used to temporarily prevent a Service Pack from being offered through Windows Update. A Service Pack block typically expires one year after a service pack was released on WU. It is useful when client updating can’t be easily managed through Windows Server Update Services (WSUS) or System Center Configuration Manager (SCCM) and the IT administrator needs control over which Service Packs are offered through WU.
