XP update delayed over glitch

Microsoft on Tuesday said it is delaying the release of Windows XP Service Pack 3 because of a newly uncovered glitch.

The software maker said there is a "compatibility issue" between the XP service pack and Microsoft Dynamics Retail Management System, a retail chain management program for small and midsize businesses.

Microsoft finalized the code for Windows XP SP3 last week and had planned to make it broadly available starting Tuesday.

"In order to make sure customers have the best possible experience, we have decided to delay releasing Windows XP SP3 to Windows Update and Microsoft Download Center," the company said in a statement.

The glitch also exists between Microsoft Dynamics RMS and Windows Vista Service Pack 1, though that product has already been broadly released. Microsoft started pushing out Vista SP1 last week via Automatic Updates.

"To help protect our customers, we plan to put filtering in place shortly to prevent Windows Update from offering both service packs to systems running Microsoft Dynamics RMS," Microsoft said. "Once filtering is in place, we expect to release Windows XP SP3 to Windows Update and Download Center."

Microsoft advised those running Microsoft Dynamics RMS to not install either service pack. The company said a "fix is currently in testing and will be available as soon as that process is complete."
