How to purchase your key and activate your new software

Keysbuff’s purchase and activation processes are straightforward and simple to follow. On the software activation key purchase page for the product you want, just click the Buy Now button. Then you simply sign up quickly for your free Keysbuff account (or log in if you’re a repeat customer). After you complete your purchase, you will receive your software activation link via email.

After you follow the link and receive an OEM product key at the email address you entered during registration, go to Windows 10 Settings. Just click Start > Settings > System > About the program > Change product key, and then enter your 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.”

Installing and activating new software via Microsoft is also a straightforward process. For example, let’s say you want to activate a Microsoft Office package. Just follow these steps:

1. Go to the official Microsoft page for the Office software.
2. Enter your Microsoft credentials (or create a profile if you do not already have a Microsoft account).
3. Enter the purchased product key in the appropriate field (from the Keysbuff email you received after your purchase).
4. After selecting your language and region, click Next to complete the activation.
5. Now you can install Microsoft Office on your PC.
