Warp2Search let us know they've posted an updates page for IE 6 & Windows XP. It's basically the same thing as our OS Updates page, except rather than having everything listed on 1 convenient page (As we do :)), they've split it up across 3 & 12 pages respectively in reverse order. That said they do have a few updates pointed out that we don't (Mainly as microsoft have yet to download links to the knowledge articles for them).
