Not to argue, but...
I didn't see anything there about corrupt icon files and honestly, an icon is just a bitmap with a different name - an uncompressed image file. You can open a 16 to 256 color icon in Notepad, resize it to 16 or 32 characters accross (depending whether it's a 16 x 16 or a 32 x 32 icon) and see the image sort of - it's kinda cool
But other than that there's a header telling it how many colors, etc - nothing at all that can corrupt a system...
The privacy concern is very real though, and it's one I hadn't thought of - sites can easily track users that bookmark a site, for marketing reasons, etc - and that sux

And really there's no way around it because you can't turn the "feature" off...
MS at it's best
