Months before its official release, Windows 7 has already found its way to major file-sharing websites. Hackers have posted a pirated copy on the net, luring users who have long been waiting for the software's release. Microsoft has verified the breach and has warned against downloading the software to avoid security issues. "We are aware of reports of hacks that attempt to circumvent activation and validation in Windows 7, and we can assure customers that Microsoft is committed to protecting them from counterfeit and pirated software. Microsoft strongly advises customers not to download Windows 7 from unauthorised sources," Microsoft noted. "Downloading Windows 7 from peer-to-peer sites is piracy, and exposes users to increased risks, such as viruses, Trojans and other malware, that usually accompany counterfeit software. These risks can seriously harm or permanently destroy data, and often expose users to identity theft and other criminal schemes." Despite the risks brought by downloading from p2p sites, users have already copied the software and were able to successfully activate it. The leak is attributed a Lenovod source code key that was posted on the web last week.
