You can click here to begin submitting a Windows Update support request. Like with Windows XP you can receive help for Vista update issues free of charge. (You also receive free support on an unlimited number of Vista-related issues for the first 90 days after activation.)
As to your other points:
* Have you tried using the WGA tool for Firefox instead of the ActiveX version of IE7? You'll automatically be prompted to download the tool should you attempt a WGA-protected download from Microsoft.
* That update applicability issue seems to be spreading...I've encountered it myself now.
* Changing your product key would have no effect on this.
Hope this helps,
I'm running Vista Business. When I was running XP Pro SP2 if you had a problem down loading updates/KBs from Microsoft there was a link to free support from Microsoft concerning these problems. Is this service available for Vista? Where is it? I'm having several problem: I have to use the validation tool to download from Microsoft sites. (my automatic updates work fine for the most part.) The ActiveX download software does not work for me so each time I have to do it manually. When it does work it often says that the update has failed to install because the KB is not for my computer, when by all appearances it is compatible. All of these problems are annoyances and not critical but I would like to get this straightened out. I need MSN support for these.
One last item, would changing the product key fix these problems or a least some of them. Product key can be found by: click, start>click, control panel>click, system> it is listed at the bottom of the window.
