Read this before you order Windows 10 Pro

Microsoft ended mainstream support for Windows 10 on 14 October 2025. Since then the operating system no longer receives routine security updates, feature updates or technical support on the standard consumer lifecycle, unless a machine is enrolled in Microsoft’s Extended Security Updates programme. That is a security consideration rather than a licensing one: a Windows 10 Pro licence key still activates, but Microsoft is no longer patching the software behind it as standard.

If your hardware can run it, Windows 11 Pro is the supported equivalent and our recommendation for any machine that handles email, banking or business data. Where the hardware cannot, this page supplies Windows 10 Pro as a pre-owned digital licence with documentation and activation guidance.

What Windows 10 Pro includes

• BitLocker: full-drive encryption for laptops and portable machines.
• Domain join and Group Policy: management through a company directory with centrally applied settings.
• Remote Desktop host: the machine can be connected to, not only from.
• Hyper-V: local virtual machines for testing and isolation.
• Familiar desktop: the Windows 10 Start menu, taskbar and settings that many legacy applications were certified against.

Why people still buy Windows 10 Pro

There are legitimate reasons. Older hardware without TPM 2.0 cannot take Windows 11. Industrial, laboratory and studio equipment is often certified against Windows 10 and its vendor drivers. Offline or air-gapped machines carry a different risk profile. Where one of those applies, this is the edition with the business features; where none applies, buy Windows 11 Pro instead.

If you go ahead, treat an unsupported operating system accordingly: keep it off untrusted networks where possible, keep separate security software such as Kaspersky Standard up to date, and plan a replacement path. Extended Security Update arrangements exist for some Windows 10 scenarios; eligibility and cost are set by Microsoft and are not part of this listing.

Windows 10 Pro versus Windows 11 Pro

Compatibility and system requirements

Windows 10 Pro 64-bit needs a 1 GHz processor, 2 GB of RAM (4 GB recommended), 20 GB of storage and a DirectX 9 graphics adapter with WDDM driver — far lighter than Windows 11. Installation media is downloaded from Microsoft; an internet connection is needed for activation.

Microsoft’s lifecycle dates are published on the Microsoft Lifecycle site.
