How to Check if Windows Validation Is Genuine

By Erika Dean

If you have not validated your copy of Windows, do so by going to Microsoft's website. It is important to validate Windows so you can download Windows updates and know you aren't running a pirated version of Windows on your computer. Spend a few minutes going through the validation process to confirm your copy of Windows is genuine.

Step 1

Go online to Microsoft.com and click "Validate" from the tab at the top of the page.

Step 2

Click the "Validate Windows" tab located in the "Validate Now" box to the left of the screen.

Step 3

Install a plug-in if you are using the Mozilla Firefox browser. Click "Save File" when you are prompted to install the plug-in. After the file downloads, click "Open" and the plug-in will install. Refresh your browser.

Step 4

Click "Continue" to continue validating your copy of Windows and click "Validate Now." Microsoft will check your copy of Windows. If your copy is genuine, "Validation Complete" will appear on a new page.

Tips & Warnings

  • If your copy of Windows is not validated, go through the steps on the troubleshooting page that opens when you are told that Windows wasn't validated. For example, you may have entered an incorrect product key when you set up your computer and you will receive instructions to check this.
  • If the troubleshooter doesn't help you, send a technical support request to Microsoft.
