Windows 11 Editions
Windows 11 Home
The ideal operating system for personal desktops and laptops. Windows 11 Home delivers Microsoft's most refined interface to date — featuring the redesigned Start menu, Snap Layouts for multi-window multitasking, DirectStorage for rapid game load times, Windows Hello biometric login, and improved touch and pen support. Available as a Retail license (transferable) or OEM (device-locked, lower cost).
Windows 11 Pro
Everything in Windows 11 Home, plus a comprehensive suite of business and power-user features: BitLocker full-disk encryption, Remote Desktop, Windows Sandbox, Hyper-V virtualisation, Azure Active Directory join, and advanced Mobile Device Management (MDM). The essential upgrade for businesses and professionals. Available as a Retail license or OEM key.
Windows 11 Pro N
The European Union-compliant edition of Windows 11 Pro. Functionally identical to standard Pro, but ships without Windows Media Player and certain bundled media components to comply with EU competition regulations. All other Pro features are fully included. Best for EU-based businesses and organisations with regulatory requirements.
Home to Pro Upgrade Key
Already running Windows 11 Home and want to unlock Pro features without reinstalling? Our Windows 11 Home to Pro upgrade key activates the upgrade in minutes directly through Settings. No data loss, no reinstallation — just enter the key and your PC becomes Windows 11 Pro instantly.
OEM vs Retail — Which Should You Choose?
- Retail: Fully transferable — move it to a new PC if you upgrade your hardware. Ideal for users who plan to build multiple machines over time.
- OEM: Permanently tied to the first PC it activates on. More affordable — the smart choice for system builders, IT professionals deploying specific hardware, and single-machine upgrades.
Does Your PC Support Windows 11?
Windows 11 requires a 64-bit processor (1 GHz+, 2 cores), 4 GB RAM, 64 GB storage, a DirectX 12 compatible GPU, TPM 2.0, and Secure Boot. Use Microsoft's free PC Health Check app to verify compatibility before purchasing. If your PC does not meet Windows 11 requirements, browse our Windows 10 license keys for a compatible alternative.

Frequently Asked Questions
Is Windows 11 a free upgrade from Windows 10?
Microsoft previously offered a free upgrade from Windows 10 to Windows 11 for eligible hardware. This may still be available via Windows Update for compatible PCs. Our keys are for new activations or upgrading from Home to Pro within Windows 11.
Can I use Windows 11 offline?
Windows 11 Home requires a Microsoft account and internet connection during initial setup. Windows 11 Pro can be set up with a local account and used offline after activation.
What happens if Windows 11 doesn't activate?
All our keys carry a 30-day warranty. If a key fails to activate, contact us immediately — we will provide a resolution or replacement at no cost.
Is there a performance difference between Windows 11 Home and Pro?
No. Both editions offer identical performance. The difference is purely in features — Pro adds BitLocker, Remote Desktop, Sandbox, and enterprise management capabilities.
