Earlier this week we reported that the Windows 7 OEM master key had been leaked to the web. The leak could have resulted in the activation of an unlimited number of copies of Windows 7 OEM editions. However Microsoft has moved fast to combat the issues and according to Alex Kochis, Director of Genuine Windows at Microsoft, Microsoft has blacklisted the key, delivering a new key to Lenovo.
Kochis said Microsoft is working with Lenovo to ensure that all the Windows 7 based PCs the company ships will contain a new key and none use the old key. All Windows 7 installs using the leaked key will be blacklisted and customers will be warned that they have a non-genuine version of Windows.
