I know that it's a fallacious statistic but here is the VLC all time OS market share (rounded):
Windows: 89.38%
OS X: 10.27%
Other: 0.35%

With VLC and Firefox et al, I know reinstalls contribute to a lot of "downloads" numbers. I take the number at face value: it's popular enough to have been downloaded 1 billion times, regardless of how many people are using it right now.
I have written off ever trying to make that drive look pretty again without breaking everything, but it does still boot and I think all the applications start. Baby steps M$!
I blame Dell for this issue though, not win7.
Incremental updates like that could artificially inflate the download numbers. Take that and multiply it by the number of computers you have.
Big numbers are still impressive though.
