Why do I need Windows 7 Product Key?

After installing Windows, within 30 days you must activate via the Internet or by phone. Windows must be enabled before the end of this 30-day period.

The whole activation process consists in the fact that the user enters a special code called an activation key through a special interface. The maximum system performance is achieved only after this process has been completed.

Windows then contacts the Microsoft servers to authenticate the password entered. If the key fits, your OS immediately gets the status of a licensed one. It is worth noting that the codes differ for each Windows distribution – for example, Corporate or Maximum cannot be activated using codes from the Professional or Ultimate versions.

Often when you install Windows 7 Ultimate you need enter the activation key to continue. It is clear that the activation will dismiss after installation, but Windows will be installed.
