Built to detect and prevent installation of pirated or illegal copies of software, WGA failed genuine copies of Windows in large numbers for reasons never explained.
One in five PCs running Windows XP have failed WGA tests since July 2005, but less than 0.5 per cent were reported to be running counterfeit software, according to figures from Microsoft released in January 2007. In 2006, Microsoft said that more than 20 per cent of WGA failures had been caused by something other than piracy of the keys used to activate the software.
Along the way, alerts would pop up. If WGA found your copy of Windows to be not genuine, unauthorized or not validated, you got repeated warnings of: "This copy of Windows is not genuine".
Despite these failures, Microsoft remains committed to the idea of WGA - hence the name change to break from the past as it introduces a brand new operating system.
If you chose not to activate your copy of Windows 7 immediately, the company said Thursday, you're still going to get an annoying alert - but more in the vein of a peppy and irritating health and safety manager than a harsh headmaster ready with the cane. According to Microsoft, it hasupdated the Windows Vista SP1 reminder so: "When customers choose to activate later they will see a dialog box highlighting how activation helps them identify if their copy of Windows is genuine and be allowedto proceed immediately without a 15-second delay."http://www.theregister.co.uk/2009/05/07/microsoft_wga_rebranding/
