Last Wednesday, Microsoft pulled both SP1 for Vista and SP3 for XP due to a conflict that arose between one of their own products (how that wasn’t caught in testing is anyone’s guess). For those who were on the verge of freaking out, calm down, as they’ve thrown both service packs up and you are able to download them via normal methods.
Sadly though, the fix is not actually a fix, but a workaround. The good thing is that it will affect virtually no one, however, except those in small businesses. If for some reason you are in a situation where you have the Dynamics Retail Management System installed, a filter will block the download, so you are safe either way.
As mentioned before, there will be nothing new for home users other than bug fixes, but network administrators should be pleased with the addition of MMC 3.0 support, MSXML6, IPsec filter creation and also network access protection (NAP).
For those who prefer not to use Windows Update, you can either download an ISO or full executable.
The software maker on Tuesday said it is releasing XP Service Pack 3 for Web downloads, and resuming automatic updates to Vista Service Pack 1, after developing a filter that will prevent machines running Dynamics RMS from getting either update. The filter is not a fix for the incompatibility, though Microsoft said it is working on that as well.
