Microsoft Corp. has announced plans to broaden its anti-piracy "Windows Genuine Advantage program" in effort to combat piracy of its flagship operating system Windows. The company will extend the program to 20 new languages in February and limit access to most software updates to users who authenticate their Windows software. In July 2004, results for the Business Software Alliance Global Software Piracy Study conducted by International Data Corp. showed 36 percent of the software installed on computers worldwide was pirated in 2003. Microsoft aims to reduce the impact of pirated software on legitimate software resellers and economies around the world, which lose nearly US$ 29 billion a year to pirated software. Tomshardware reports Microsoft will leverage its download content and access to updates for its software, such as additional content, patches and security fixes, to make purchasing its software more attractive: The pilot program launched in September of last year, encouraged users to type in the serial number of their operating system, before they were able to download additional content such as the firm's recently announced anti-spyware. Microsoft will offer free downloads of Photo Story 3, Winter Fun Pack 2004, rebates for MSN Games, Windows SharePoint, List Builder and Outlook Live to entice users to take part in program. A mandatory authentication of software for most downloads is expected to be implemented by midyear. Microsoft is offering a genuine version of Windows at a reduced price for those who discover that they have been sold counterfeit versions of Windows. The price varies from $10 to $150 depending on the country.
