Re: WGA
http://en.wikipedia.org/wiki/Windows_Genuine_Advantage#False_positive_rate False positive rate The WGA program can produce false positives (incorrectly identifying a genuine copy of Windows as "not genuine"). This can happen for any number of reasons such as failed updates, etc. Microsoft has established a forum to help users encountering problems.[34] In February 2007, a "Not Sure" section was added to the program, in case of an incorrect reading.[35]According to an editorial on the arstechnica.com technology website, WGA reported around 22% of 500 million Windows computers as failing the test; of these less than 0.5% were due to pirate software, with the balance (over 20%, or 90% of all positives) related to non piracy issues. Microsoft "refused to comment on the rate of pure false positives" beyond saying it was "under 1%" (or as stated, at most around 5 million users affected).[36] [edit]False negatives On June 18, 2007, news surfaced that it is possible to positively validate as a "Genuine Microsoft Product" user (and as a result be able to download certain software from Microsoft's official website) using Internet Explorer with IEs4Linux and Wine, running on Linux,[2] without even having a Windows-family system installed. [edit]Major failures in WGA system From the moment that WGA was released, it had a flaw that allows a typical user to remove the program without uninstalling its root key, causing Windows to think that the software is installed although no "nagging" process or RAM usage occurs.[citation needed] This flaw has not yet (June 2009) been fixed, although it still prevents critical system updates.[citation needed]On October 5, 2006, a WGA failure occurred, incorrectly flagging some systems as being non-genuine.[37]On August 25, 2007, the Microsoft WGA servers suffered an outage, resulting in many legitimate copies of Windows XP and Vista being marked as counterfeit.[38] The issue was solved about twelve hours later. According to Microsoft, "fewer than 12,000 systems were affected worldwide."[39]On July 18, 2008, reports of Microsoft's WGA and OGA servers being offline surfaced again. Microsoft later responded that only offline verification was temporarily down.[40]
