How to activate Microsoft software keys

If you’ve never bought software activation keys before, don’t worry. We’ll walk you through the process. We promise that it’s simple and straightforward. First, go to CdkeySales.com. On the software activation key purchase page for the product you want, just click the Buy Now button. (What could be simpler, right?)

Then just sign up quickly for your free CdkeySales account (or log in if you’re a repeat customer). After you complete your purchase, you will receive your software activation link via email. And it’s well worth it. Just look at the official price of Windows 11 Pro in the graphic below. Compare that to CdkeySales’ price of $22.71 (or a free upgrade from Windows 10 Pro). On Microsoft’s official web page, Windows 11 Pro sells for $199.99, which is nearly nine times what CdkeySales charges.

Next, click on the link in the email you received to get your OEM product key. Then go to Windows 10 Settings. Just click Start > Settings > System > About the program > Change product key, and enter your new product key. After you activate the OEM key, you should see the following message on the activation page: “Windows is activated with a digital license linked to your Microsoft account.”

Install and activate new software after you score software deals on Microsoft Windows

3. Enter the purchased product key in the appropriate field (from the CdkeySales email you received after your purchase).
