Months after its original release, the very slowly paced rollout of Windows XP SP3 is still in process. Now, after having enough time to study the issues involved in the upgrade, Microsoft is preparing to push the Service Pack again through Automatic Updates. As a token to IT admins who are worried about machines becoming mass-crippled in the event of a problem, Microsoft is offering the Windows Service Pack Blocker Kit, as well as playing up WSUS control. The company still has to publish an exact date on the release, but knowing Microsoft, it will most likely be on a Tuesday, so watch out.
You might recall Windows XP SP3 went RTM in late April. However, despite extensive planning and a staged rollout, a number of issues became evident soon thereafter under certain scenarios which has prevented its en masse adoption as it was originally intended.
