Yesterday we announced the release to manufacturers (RTM) of Service Pack 3 (SP3) for Windows XP, and as noted on Computerworld...

"Windows XP has released to manufacturing," said Chris Keroack, the service pack's release manager, in a message posted to a TechNet support forum Monday at around 1 p.m. EDT. "Windows XP SP3 bits are now working their way through our manufacturing channels to be available to OEM and enterprise customers."

If you are an IT systems administrator, developer, or if you're no stranger to installing updates from the DLC, you will be able to update XP systems to SP3 next week when SP3 is released on the Download Center, or as an optional download on Windows Update. 

For consumers, you'll start to see XP SP3 distributed via Automatic Update in early summer.
