How to Use Generic Windows Installation Keys

Whether you’re reinstalling, repairing, or evaluating Windows, using a generic installation key is simple and fully supported by Microsoft for temporary use. Here’s how to use generic keys for Windows 7, 8, 10, and 11.

Windows 11 & 10

  1. Download the official Windows Media Creation Tool from Microsoft.
  2. Prepare a USB installation drive and boot your PC from it.
  3. When prompted for a product key during setup, enter the generic key from our Key Generator tool.
  4. Continue setup; Windows will install but remain unactivated until you enter your purchased license.
  5. After installation, activate Windows using your genuine license key through Settings > Update & Security > Activation.

Windows 8 / 8.1

  1. Download the Windows 8.1 ISO or use original media.
  2. Boot from your installation media.
  3. When asked for a product key, use the generic key matching your edition.
  4. Complete setup, then activate later with your own license.

Windows 7

  1. Install Windows 7 from DVD or USB.
  2. When prompted, enter the generic key for your edition (Home, Pro, etc.).
  3. Complete install and activate after setup if you have a valid product key.

Important: Generic keys do not activate or validate Windows permanently. They only allow installation or temporary access. Always use a legal, genuine license for ongoing use.
