In the last few days, we have uncovered a compatibility issue between
Microsoft Dynamics Retail Management System (RMS) and Windows XP SP3 and Windows Vista Service Pack 1 (SP1). Microsoft Dynamics RMS is a retail chain management solution for small and midsize customers.
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.
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. Once filtering is in place, we expect to release Windows XP SP3 to Windows Update and Download Center.
Until we have published a fix for this issue, we advise
Microsoft Dynamics RMS customers to not install either service pack.
Microsoft Dynamics RMS customers running Windows XP SP3 or Windows Vista SP1 should contact Microsoft Customer Support Services for additional
information. The fix is currently in testing and will be available as soon as
that process is complete. For further information regarding Windows XP
SP3, please visit the TechNet Forum.
While I've seen this referred to as a cock-up once today already we have to give Microsoft credit for how well the development of SP3 has gone and from the quote above it appears as though this problem is going to be fixed very quickly. For anyone desperate to get SP3 it can be downloaded from the Microsoft website. Paul has a link to the download on his blog.
