Microsoft has an RSS feed product index that lists the most recently published KB articles on most of Microsoft platforms and technologies.
For those of you who love to subscribe to RSS feeds (either via outlook or by any other RSS reader) this is a great way to keep updated upon most recent KB's from Microsoft.
The link to the RSS Feed Product Index is: http://support.microsoft.com/selectindex/?target=rss#top
Another website that offers the same RSS feeds is KBalertz.com
Enjoy...
