With the release of this latest data, Microsoft said that WGA had a false positive rate "under 1 percent." A more precise number has not been forthcoming.
This is an impressive figure until you realize that this means that as many as 5 million people were wrongly accused of being software pirates. From Microsoft's point of view, the error rate appears to be acceptable. 1 percent sounds pretty low, doesn't it? That slice grows to almost 5 percent if you talk only about false positives as a total share of all "hits" on pirated software.
The concern, of course, is scale. WGA is not in use all over the globe yet, but one can easily see how this 1 percent could bloom into truly astounding numbers. Add to this the fact that Microsoft has big plans for Office Genuine Advantage, and we start to see a world in which being accused of software piracy becomes statistically more probable than winning the Pick 5.
