Windows 11 Pro

Windows 11 Pro is the business-grade edition of Microsoft's current operating system. It includes everything in Windows 11 Home and adds BitLocker drive encryption, Remote Desktop hosting, Hyper-V virtualisation and the management tools needed to join a work network.

What does Windows 11 Pro add over Home?

• BitLocker – full-drive encryption that protects your files if the PC is lost or stolen
• Remote Desktop (host) – connect to this PC from another device
• Hyper-V and Windows Sandbox – run virtual machines and test untrusted apps in isolation
• Group Policy and domain join – connect to Active Directory or Microsoft Entra ID and manage settings centrally
• Higher hardware limits – up to 2 TB of RAM and two physical CPUs

Who is this edition for?

Choose Pro if you work from home on a company network, handle client data, run virtual machines, or want encryption without third-party software. If you only browse, stream, game and use everyday apps, Windows 11 Home covers it at a lower price.

System requirements

Windows 11 has stricter hardware rules than Windows 10, and this is where most activation and install problems start. Check your PC before buying:

• 1 GHz or faster 64-bit processor with 2 or more cores, on Microsoft's supported CPU list
• 4 GB RAM and 64 GB storage
• UEFI firmware with Secure Boot, and TPM 2.0
• DirectX 12 compatible graphics and a 720p display
• Internet connection and a Microsoft account for first-time setup

Microsoft publishes the full list on its Windows 11 specifications page. The free PC Health Check app will tell you in a minute whether your device qualifies.

Frequently asked questions

Can I upgrade from Windows 11 Home to Pro with this key?

Yes. Go to Settings > System > Activation > Change product key and enter the Pro key. Windows unlocks the Pro features without reinstalling, and your files and apps stay in place.

Is Windows 11 Pro 32-bit or 64-bit?

Windows 11 is 64-bit only. There is no 32-bit version.

My PC does not have TPM 2.0. What should I buy?

Many PCs have TPM 2.0 switched off in the BIOS rather than missing, so check there first. If the hardware genuinely does not support it, Windows 10 Pro will install, though Windows 10 is now out of Microsoft support.
