Windows 11 Pro

Windows 11 Pro is Microsoft’s most capable consumer and professional operating system, first released in October 2021 alongside Windows 11 Home. Designed for professionals, small business owners, power users, and IT-minded individuals, Windows 11 Pro builds on every feature in the Home edition and adds a powerful layer of business-grade security, management, and productivity tools. At Buy Now Key, our Windows 11 Pro range covers multiple licence types — Retail, OEM, and bundle deals — so you can find exactly the right key for your setup at a competitive price.

Why Choose Windows 11 Pro?

Released in 2021, Windows 11 introduced a redesigned interface, improved multitasking via Snap Layouts, and deep integration with Microsoft’s Copilot AI assistant. What sets it apart from the Home edition, however, is its exclusive feature set built for security and control:

• BitLocker Drive Encryption — protect your data with full-disk encryption, a must-have for business devices and sensitive files.
• Remote Desktop — connect securely to your PC from anywhere in the world.
• Hyper-V Virtualisation — run virtual machines directly on your Windows 11 Pro device without third-party software.
• Windows Sandbox — test applications in a secure, isolated environment that resets on every close.
• Group Policy Management — configure and enforce settings across multiple devices with precision.
• Azure Active Directory & Domain Join — connect to corporate networks and cloud-based identity management seamlessly.
• Assigned Access & Kiosk Mode — lock devices to a single app for dedicated-use scenarios.

Our Windows 11 Pro Licence Options

Not all licences are alike. Buy Now Key offers three distinct Windows 11 Pro licence types to match every use case and budget:

• Retail licence — the most flexible option. A Microsoft Windows 11 Pro Retail key can be transferred to a new device if you upgrade your hardware, making it ideal for personal use or anyone planning a future upgrade.
• OEM licence — permanently tied to one machine. The Microsoft Windows 11 Pro OEM key is a cost-effective choice for a single device that you don’t plan to change. Ideal for builders assembling a new PC.
• OEM multi-pack — need to activate two devices? The Windows 11 Pro OEM 2-PC bundle gives you two separate keys in one convenient purchase, with a minimum order of two licences.

Every licence delivers lifetime activation — one purchase, permanent use on the covered device(s). All keys are global, supporting all languages and regions.

Bundle Windows 11 Pro With Microsoft Office

For maximum productivity value, consider pairing your operating system with a Microsoft Office suite. Our Windows 11 Pro and Office 2021 Professional Plus bundle delivers both licences in a single purchase — two of the most essential software products for any professional workstation, activated separately and used for life. If you’d prefer to shop Office titles independently, browse our full Office 2021 category for individual suite options.

Frequently Asked Questions

What is Windows 11 Pro and who is it for?

Windows 11 Pro is the professional-tier edition of Microsoft’s latest operating system, released in October 2021. It includes all the features of Windows 11 Home plus advanced tools such as BitLocker encryption, Remote Desktop, Hyper-V, and Group Policy — making it the right choice for professionals, developers, small business owners, and power users who need greater security and control over their devices.

What is the difference between a Windows 11 Pro Retail and OEM licence?

A Retail licence is tied to your Microsoft account rather than your hardware, which means you can transfer it to a new PC if you upgrade. An OEM licence is permanently tied to the first device it is activated on and cannot be moved. OEM keys are typically more cost-effective, while Retail keys offer greater long-term flexibility.

Is Windows 11 Pro a one-time purchase?

Yes. Every Windows 11 Pro key sold at Buy Now Key is a lifetime licence — you pay once and the activation is permanent on the covered device. There are no subscriptions or recurring fees associated with the operating system licence itself.

Can I upgrade from Windows 11 Home to Windows 11 Pro using a new key?

Yes. Microsoft allows in-place upgrades from Windows 11 Home to Windows 11 Pro without reinstalling the OS. You simply go to Settings > System > Activation, select “Change product key”, and enter your new Windows 11 Pro key. The upgrade takes effect after a brief restart, with all your files and applications intact.

Does Windows 11 Pro support BitLocker on all devices?

BitLocker is available on all devices running Windows 11 Pro, provided the device has a compatible TPM (Trusted Platform Module) chip — typically TPM 2.0, which is also a system requirement for installing Windows 11. Most modern PCs manufactured after 2018 include TPM 2.0 support.

Will my Windows 11 Pro key work in any country?

Yes. All product keys sold at Buy Now Key are global licences that work across all regions and support all available language packs within Windows 11 Pro. There are no geographic restrictions on activation.
