Showing all 5 results

If you need a reliable, business-ready operating system, Windows 10 Pro remains one of the most widely deployed versions of Windows ever released. Launched on 29 July 2015, it has powered hundreds of millions of PCs across homes, offices, and enterprises worldwide. At Buy Now Key, you’ll find a carefully selected range of genuine Windows 10 Pro licence keys — covering Retail, OEM, and bundle options — all delivered digitally so you can get up and running without delay.

Why Windows 10 Pro Is Still a Smart Choice

Windows 10 Pro sits above the Home edition in Microsoft’s lineup, adding a suite of professional tools that are particularly valuable for businesses and power users. Even as Windows 11 gains traction, Windows 10 Pro continues to hold a dominant installed base — and Microsoft confirmed that version 22H2 will receive monthly security updates through October 14, 2025, giving businesses ample time to plan their transition. For anyone running hardware that doesn’t meet Windows 11’s TPM 2.0 requirements, Windows 10 Pro is the natural long-term solution.

  • BitLocker Drive Encryption — protect sensitive data on laptops and desktops with full-disk encryption.

  • Remote Desktop — connect securely to your work PC from anywhere.

  • Hyper-V virtualisation — run virtual machines directly on your device without third-party software.

  • Windows Sandbox — test untrusted applications in an isolated environment.

  • Group Policy Management — centrally control settings across multiple PCs in a business network.

  • Domain Join & Azure AD integration — seamlessly connect to corporate networks and cloud directories.

  • Assigned Access & Enterprise Data Protection — restrict device usage to specific apps and protect company data.

Choosing the Right Windows 10 Pro Licence

Not sure which option is right for you? Here’s a simple guide:

  • Choose Retail if you may upgrade your hardware in the future or want the flexibility to transfer your licence to a new PC.

  • Choose OEM if you’re activating on a single machine you intend to keep — OEM licences offer the best value per activation and are fully authentic.

  • Choose a Bundle if you need both Windows and Microsoft Office — buying together is more convenient and cost-efficient than purchasing separately.

  • Choose the 2-PC OEM option if you manage more than one computer and want a straightforward multi-device deployment.

If your hardware already meets the requirements for a newer OS, you may also want to explore our Windows 11 range — including Windows 11 Pro — for the latest Microsoft experience.

Frequently Asked Questions

What is the difference between Windows 10 Pro Retail and OEM?

A Retail licence is tied to you as the user, meaning you can transfer it to a different PC if you upgrade your hardware. An OEM licence is permanently tied to the first machine it is activated on. OEM keys are typically more affordable, making them a popular choice for users who don’t plan to change their hardware. Both are genuine, fully functional licences for Windows 10 Pro.

Is Windows 10 Pro still supported by Microsoft?

Yes. Microsoft has confirmed that Windows 10 (version 22H2) will continue to receive monthly security updates until October 14, 2025. This means your system will remain protected and up to date for the foreseeable future. For further details, refer to the official Microsoft Windows 10 Lifecycle page.

Can I upgrade from Windows 10 Pro to Windows 11 Pro?

Yes, if your hardware meets Microsoft’s minimum system requirements — including a TPM 2.0 chip, a compatible processor, and at least 4 GB of RAM — you can upgrade from Windows 10 Pro to Windows 11 Pro for free via Windows Update. If you’d prefer to start fresh with a new licence, visit our Windows 11 Pro category.

How is my Windows 10 Pro key delivered?

All licence keys at Buy Now Key are delivered digitally. After your purchase is confirmed, your key is sent directly — no physical media, no waiting for a delivery. You can activate Windows 10 Pro quickly by entering the key through Windows Settings or during the OS installation process.

Does Windows 10 Pro support domain joining and network management?

Yes. Unlike the Home edition, Windows 10 Pro supports Domain Join, Azure Active Directory integration, and Group Policy Management — making it the preferred choice for business networks, IT administrators, and corporate environments.

What if I need Windows for an older PC?

If you’re working with legacy hardware, our site also carries licences for earlier versions of Windows. Browse our Windows 10 category for additional options, or explore Windows 10 Home if you don’t need the full Pro feature set.
