How to Obtain a Replacement Product Key for Windows 7
The Windows 7 product key identifies each unique copy of Windows and is required for installation. ( Images)

Each Windows 7 disk or installation includes a unique product key which validates your copy of Windows as genuine. Without a product key Windows 7 can only be installed for a 30-day evaluation period after which you'll have to either enter a valid product key or cease using some Windows 7 features. Unfortunately for some Windows 7 users a lost or missing product key must be replaced with a new product key in order to continue using Windows.

Skill level:
Moderately Easy


  1. 1

    Visit the Microsoft online store or a local retailer that carries Microsoft Windows products.

  2. 2

    Select the version of Windows 7 that you currently have or just purchased. Purchasing an upgrade or different version of Windows 7 will provide you with a replacement product key.

  3. 3

    Enter the Windows 7 product key that you received with your new purchase when asked for your product key during the installation and activation process.
