Microsoft Windows 10 Pro

Microsoft Windows 10 Pro is the business edition of Windows 10, with BitLocker, Remote Desktop, Hyper-V and Group Policy on top of everything in Home. Buy a genuine Windows 10 Pro product key for one PC. It's ideal for older hardware that can't run Windows 11, or for matching existing Windows 10 machines.

What Windows 10 Pro Adds Over Home

• BitLocker drive encryption.
• Remote Desktop host for connecting to this PC from elsewhere.
• Hyper-V and Windows Sandbox for virtual machines and safe testing.
• Group Policy and domain join, including Azure AD / Entra ID.
• Windows Update for Business to control update timing.

Windows 10 Support Status — Read Before Buying

Microsoft ended Windows 10 support on October 14, 2025. Home users can get one extra year of security updates through Microsoft's Extended Security Updates (ESU) programme, until October 13, 2026. Windows 10 keeps working after that, but without security fixes.

Good to know: a Windows 10 key generally also activates the same edition of Windows 11 on compatible hardware, so you can move up later.

Windows 10 Pro or Windows 11 Pro?

If your PC supports it, Windows 11 Pro is the better long-term choice.

Windows 10 System Requirements

Unlike Windows 11, Windows 10 doesn't need TPM 2.0 and runs on older PCs, which is the main reason people still buy it.

Windows 10 Pro FAQ

Can I upgrade to Windows 11 Pro later?

Yes. On compatible hardware, use Windows Update or the Windows 11 installer. Your Windows 10 Pro licence generally carries over to Windows 11 Pro.

Is Windows 10 still safe to use?

Only with security updates. Enrol in ESU to receive them until October 13, 2026, then plan a move to Windows 11.

Already on Windows 10 Home?

Use our Windows 10 Home to Pro upgrade instead of a full reinstall.

32-bit or 64-bit?

The key activates both. Choose 64-bit unless you have very old hardware.

Is it a subscription?

No. It's a one-time purchase for one PC.
