Microsoft's director of official Windows Alex Kochis formally approved the leak of a "unique product key" for Windows 7 Ultimate RTM (release to manufacturers), saying that the leaked key was intended to make active copies of the latest OS pre-installed by a specific OEM partner (Lenovo).

Kochis also supposed that clients who buy PCs with Windows 7 from Lenovo shouldn't practice legalization issues in spite of the leak, yet Microsoft has motivated to avoid PCs from being sold that make use of the key in issue. His blog also point out that the leaked key will still work, but will be simply recognized.

"Windows 7 already consist of a superior capability to identify hacks, also well-known as activation develops, as well as aware clients who are using a pirated copy," he said. "There is a hack that is assumed to facilitate, when paired with the leaked key, a system to set up as well as make use of a copy of Windows 7 Ultimate. Both the hack along with the key is suggestion that a copy of Windows may not be authentic. The Windows Activation Technologies integrated in Windows 7 are intended to handle circumstances such as this one, as well as consumers by means of these tools and methods should guess Windows to identify them."

Kochis also added that Microsoft's chief objective is to guard users from suitable unknowing victims; claiming that pirates (or consumers who make use of pirated copies of Windows 7) is at a bigger threat of identity theft as well as Malware.
