Please note that some of these numbers are easier to find than others. A few of these Microsoft Windows stats come from their own reports, but some are based on news reports and not official company tallies. No information contained on DMR should be relied upon to make investment decisions. Basically, this is the best I can find and I don’t guarantee anything to be 100%
