Microsoft is delaying the release of Service Pack 3 for Windows XP users due to a "compatibility issue" with the bundle of updates and a supply-chain solution the company markets to small- and medium-sized businesses. The software giant had previously said SP3 would be released to XP customers today via Windows Update and its software download center.
Apparently they found some problems with XP SP3 with Dynamics Retail Management System (RMS), a software package for running retail stores. According to MS, SP3 should be available for download after MS puts some filters in place for systems that use RMS.
I do find it disappointing that Microsoft will hold back on updates and the like if the break one single Microsoft application, but don't pause even to think when rolling out things that break applications released by other software companies.
