Banger and caffn8me,
Although the other day, on my WinXp machine, I downloaded that patch with the long alphanumeric string in its filename, I've not installed it yet. Call me paranoid if you like but I've had an uneasy feeling about it from the outset.
Doing a bit of background research on the patch (using my Mac), I've discovered in a Microsoft Answers forum that - apparently - lots of people with XP SP3 x86 machines have been experiencing failures of this file to install, and word has it that, at the catalog site, Microsoft has posted up the wrong file. (Here, we're talking about the one that's near the top of that catalog list). Whereas XP SP3 x86 machines require a file that suits a non-embedded SP3, the version that Microsoft's posted on the site for that is, so everybody seems to think, the embedded version. Consequently, when people try to install the file it fails and they get the message "The version of Windows does not match the update you're trying to install".
Others in the Microsoft Answers forum maintain that if instead of using the catalog site you use the XP SP3 x86 link tucked away with others in the blogs.technet.microsoft.com article, you get the correct file. It's one without a whopping great alphanumeric string in its title.
At the catalog site there are at least three different versions of the patch made available for WinXP SP3 x86 (32-bit): a non-embedded version, an embedded version, and a POS (commercial upgrade) version. There's also a 64-bit version there. But it seems that Microsoft's dropped a clanger and got some of them mixed up, and now nobody's quite sure which one they should download and use. Indeed, there's now just as much doubt cast on the blogs.technet version. The link on the blogs.technet page renders you just one, single short-named file, which if you look at its details is apparently good for all versions of XP SP3.
Why on earth can't people be more precise about these things?! Accuracy is all-important. And it surely isn't rocket science to post the correct patch for the particular version, is it? So much for the 'emergency wonder patch' that the media's been raving about since Saturday; the facts don't fit the media hype. I for one will not be installing the patch until such time that it's 100% certain which one it is!
