Software like the new Internet Explorer 7 or the Windows Media Player can only be downloaded after a successful WGA check. The download and installation will be denied if a check fails.

It was always known that there would be false positives and the new figures give us a clearer picture on the scale of the false positive rate. About 114 million systems failed the WGA check since the introduction of those checks and Microsoft admitted that 1% of those were false positives meaning that legit Windows systems failed the WGA check.

While under 1% does not seem that much it it does look much in absolute figures: 1% of 114 million checks means that 1.14 million systems failed the check although this should not have happened. I can’t figure out how the source comes to the conclusion that the absolute number would be 5 million false positives because you clearly have to use the failed checks for the figure and not the total amount of checks which is 500 million.

It is nevertheless a huge number and Microsoft should do everything to reduce it by optimizing the script that performs the checks.

Several users had problems installing the software afterwards because a second check was performed during the installation of the software. It did not install if the check failed and there was not way to prevent the check from happening.
