Microsoft on Monday sent out a reminder that it would distribute a new version of Service Pack 3 for XP through its Automatic Update service "shortly."

Nick MacKechnie, senior technical account manager at Microsoft New Zealand, said in a company post that if IT administrators wanted to prevent the automatic installation then they should and deploy the Windows Service Pack Blocker Kit from or deploy update management that provides full control over updates deployed to computers on a network.

In posting the reminder, Microsoft is apparently trying to prevent problems similar to the ones that followed the release of the software to the general public in May. Within hours of its release, SP3 from users who claimed the update wreaked havoc on their PCs.

"We would like to remind you that Windows XP Service Pack 3 will be released to Automatic Updates shortly," MacKechnie said. "The third service pack to Windows XP includes the previously released updates and hotfixes to Windows XP, creating a new baseline for servicing."

Problems with the first version of SP3 ranged from spontaneous reboots to outright system crashes. It's not uncommon for major updates to cause problems. Typically, the glitches are due to conflicts with software, such as drivers, system files, or applications already on the user's PC.

The original service pack offered a number of enhancements over the current version of the OS, which Microsoft started phasing out after June 30. It included all updates issued since Windows XP Service Pack 2 was released in 2004, and some new elements.
