How Do I Activate My Copy Of Windows 7?

Last Update date : 2014.11.22

Genuine Windows

Genuine Windows is a copy of Windows that's licensed and published by Microsoft. With a genuine copy of Windows, you're eligible to receive the latest updates from Microsoft. Genuine Windows is published by Microsoft, properly licensed, and supported by Microsoft or a trusted partner. Only genuine Windows customers have access to all optional updates and downloads available from Microsoft, which are designed to help you get the most from your PC.

Activation pairs your product key with your hardware configuration and helps verify that your copy of Windows hasn't been used on more computers than the Microsoft Software License Terms allow. The genuine, or validation, check is performed when your computer attempts to download optional updates from Microsoft. For example, when your computer downloads updates, Windows checks to see if your product key is valid. If it is, Windows on your computer is genuine, and you're eligible to receive the latest updates from Microsoft. If it's not, your computer is running non-genuine Windows.

Activating Windows

If your copy of Windows cannot validate it as a genuine copy, you will receive an error message asking you to activate or validate your copy of Windows.
