Frequently Asked Questions — Windows 10 Pro OEM + Office 2021 Pro Plus OEM Bundle

What is included in the Windows 10 Pro OEM + Office 2021 Pro Plus OEM Bundle?

The bundle includes two genuine OEM licence keys: one for Windows 10 Pro (32/64-bit) and one for Office 2021 Professional Plus. You also receive official Microsoft download links and step-by-step installation and activation instructions. Everything is delivered digitally to your email — no physical media required.

What does OEM mean for this bundle?

OEM (Original Equipment Manufacturer) licences are tied to the specific device on which they are first activated. This means your Windows 10 Pro and Office 2021 Pro Plus keys are permanently linked to one machine and cannot be transferred to a different computer. They are fully genuine Microsoft licences that activate normally via Microsoft’s servers.

How do I activate Windows 10 Pro after purchasing?

Once you receive your key by email, download the official Windows 10 installation files using Microsoft’s Media Creation Tool, install the operating system, and enter your product key when prompted during setup — or go to Settings → Update & Security → Activation and enter it there. Full step-by-step instructions are provided with your order. You can also visit our Windows 10 Pro activation guide for detailed help.

How do I activate Office 2021 Pro Plus?

Download the official Office 2021 installer from Microsoft using the link provided in your order email. Run the installer, and when prompted, enter your Office 2021 Pro Plus product key. Activation is completed online automatically. No Microsoft account is required — Office 2021 is a one-time purchase with permanent, offline-capable activation.

Is the Windows 10 Pro OEM + Office 2021 Pro Plus OEM Bundle a lifetime licence?

Yes. Both the Windows 10 Pro and Office 2021 Pro Plus licences in this bundle are permanent one-time purchases. There are no monthly fees, subscriptions, or renewals. Once activated on your device, they remain active for the lifetime of that machine.

How quickly will I receive the product keys?

Delivery is instant and digital. After your payment is confirmed, your licence keys and download links are sent directly to your email address — usually within minutes. If you do not see the email, please check your spam/junk folder before contacting support.

Is the Windows 10 Pro OEM + Office 2021 Pro Plus OEM Bundle compatible with my PC?

The bundle supports both 32-bit and 64-bit systems. Minimum requirements for Windows 10 Pro include a 1 GHz processor (2 or more cores), 2 GB RAM (4 GB for 64-bit), and 32 GB of available storage. Office 2021 Pro Plus requires a 64-bit version of Windows 10 or later for full functionality. An internet connection is needed for the initial download and activation.

What apps are included in Office 2021 Pro Plus?

Office 2021 Professional Plus includes the full suite of desktop productivity applications: Word, Excel, PowerPoint, Outlook, OneNote, Access, Publisher, Teams, and Skype for Business. All apps are installed locally on your PC and do not require a Microsoft 365 subscription to use.

Can I use this bundle on more than one PC?

No. OEM licences are single-device only. Each key activates on one machine and is tied to that hardware permanently. If you need licences for multiple devices, take a look at our Windows 10 Pro Retail + Office 2021 Pro Plus Retail Bundle, or contact us for volume licensing options.

What is the difference between this bundle and the Windows 11 Pro OEM + Office 2021 bundle?

The main difference is the operating system.
