Don’t delay, these deals end soon

Would you like to get great software at Keysbuff’s special prices? Don’t even think about putting it off until another day. The deals — in some cases, as much as 91% off the full price — are limited-time offers. They won’t last long. And supplies of these software activation keys are limited, too.

Also note that the keys sold by Keysbuff are activated on software downloaded from the official software provider website or activated directly on the official website. But don’t worry — we’ll walk you through the process.

Buy keys and activate software with these steps

The purchase-and-activation process at Keysbuff.com is simple to deal with. On the software activation key purchase page for the product you want, just click the Buy Now button. Then 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.

Score a free Windows 11 upgrade

Keysbuff offers great software at amazingly affordable prices. And it gets even better when you consider that you can get a free upgrade to Windows 11 when you buy a Windows 10 key.

Let’s say you want to build a custom PC for gaming. You can buy a Windows 10 software activation key at Keysbuff.com now and get a free upgrade to Windows 11. Then your gaming rig will zip along with the latest Microsoft operating system and all its improvements.

Once you have Windows 10 installed, you can proceed to upgrade to Windows 11 for free. To do this, you must update your operating system from Windows Update (click on Start > Settings > Update and security > Windows Update). Install all the updates that Windows offers until you see the option to update to Windows 11.

If you encounter any problems before or after purchase, just contact Keysbuff’s customer service department via email at [email protected].
