Windows 11 Pro

Windows 11 Pro: The Professional's Foundation for Modern Work

Windows 11 Pro is not just an operating system; it is the digital backbone for professionals, small businesses, and power users who demand more from their PC. This is Microsoft's definitive desktop platform, fusing a calm, intuitive interface with the advanced security and management tools required in a modern, hybrid work environment. Whether you are a developer needing a local virtualisation sandbox, a business owner safeguarding sensitive client data with powerful encryption, or a remote worker who needs to connect securely to the office, Windows 11 Pro provides the robust, trusted foundation you need.

This genuine, full Retail license unlocks the complete Windows 11 Pro experience as a one-time purchase, not a recurring subscription. It is a permanent license for the lifetime of your device, granting you access to all the professional-grade features absent from the standard Home edition. From the moment your key arrives, you gain the ability to join corporate domains, manage your system with Group Policy, and secure your entire drive with BitLocker. It is the definitive upgrade for anyone who has outgrown the limitations of a consumer operating system and needs a serious, secure environment to do their best work.

Key features and benefits

• Advanced Security with BitLocker Device Encryption: Protect your intellectual property and personal data from physical theft. BitLocker encrypts your entire system drive, rendering data unreadable without authorised access. This is a critical layer of defence for laptops and business desktops, ensuring that lost or stolen hardware does not become a data breach.
• Full Remote Desktop Connectivity: Stay productive from anywhere. The built-in Remote Desktop feature allows you to connect to your PC from another device, giving you secure access to all your applications, files, and network resources exactly as if you were sitting at your desk. It is your personal, private cloud workstation.
• Hyper-V Virtualisation Sandbox: Run multiple operating systems on a single machine without third-party software. Hyper-V lets you create and manage virtual machines, providing an isolated, safe environment to test new software, run legacy applications, or spin up development servers. This turns your desktop into a powerful development and testing lab.
• Azure Active Directory & Domain Join: Seamlessly integrate your PC into a managed corporate network. Unlike Windows 11 Home, the Pro edition can join a traditional on-premises Active Directory domain or connect directly to Azure AD, enabling single sign-on to cloud apps and centralised device management by your IT department.
• Group Policy Management: Give IT administrators fine-grained control over system configurations. Group Policy allows you to enforce security settings, deploy software, and standardise the user experience across an entire fleet of Windows 11 Pro devices, reducing support overhead and locking down sensitive environments.
• Windows Information Protection (WIP): Separate work and personal data without switching applications. WIP helps protect against accidental data leaks from apps and services like email, social media, and the public cloud, which are outside of the enterprise's control, without requiring changes to your working environment.
• Assigned Access & Kiosk Mode: Lock down a device to run a single application for a specific purpose. Ideal for point-of-sale systems, customer-facing kiosks, or public-access terminals, this feature ensures users cannot access other applications or system settings, creating a secure, purpose-built appliance.
• Dynamic Provisioning: Transform a brand-new PC into a fully-configured, organisation-ready device in minutes. With Windows 11 Pro, you can use a simple provisioning package to apply settings, profiles, and even join Azure AD without the need for traditional, time-consuming re-imaging.
• Support for Enterprise-Grade Hardware: Unlock the full potential of high-performance workstations. Windows 11 Pro supports up to 2 TB of RAM and configurations with up to two physical CPUs, ensuring that even the most demanding computational tasks, from 3D rendering to complex data analysis, run without a bottleneck.
• The Modern Windows 11 Interface: Experience a refined, distraction-free workspace. Snap Layouts and Snap Groups revolutionise multitasking by intelligently organising your open windows, while virtual desktops let you create separate, clean workspaces for different projects or aspects of your life.

What's included with your purchase

Your purchase from Lizensa provides everything you need to get Windows 11 Pro running on your PC. You are buying a single, genuine Retail license key. This is a permanent, one-time purchase that does not expire and is not tied to a recurring subscription. It is the most flexible license type, allowing for future hardware changes that are more restrictive with OEM versions.

Upon completing your order, you will receive a confirmation email containing your unique 25-character product key. Alongside the key, you will find a direct link to download the official Windows 11 installation media from Microsoft's servers, ensuring you have a clean, unmodified source. We also include a step-by-step activation guide that walks you through both a fresh "clean install" on a new or formatted drive and an in-place upgrade from a previous version of Windows, such as Windows 10. A full VAT invoice is provided with every purchase, essential for business accounting and warranty purposes.

Which Windows edition is right for you?

Choosing the correct Windows edition is crucial for matching your needs without paying for unnecessary features. The choice typically comes down to Windows 11 Home versus Windows 11 Pro.

Windows 11 Home is the standard consumer edition, perfect for everyday use, browsing, streaming, and gaming. It includes core security features like device encryption and Windows Hello, but it lacks the advanced business and management tools. If you are a home user who never needs to connect to a corporate network or manage sensitive business data, Home is a capable choice.

Windows 11 Pro is the professional upgrade. It is designed for small to medium-sized businesses, power users, and anyone who works from home and needs to connect securely to a corporate domain. The key differentiators are BitLocker for full-drive encryption, Remote Desktop for connecting to your PC, Hyper-V for running virtual machines, and the ability to join a domain or Azure Active Directory. If you handle client data, need to test software in a sandbox, or your IT department manages your device, you need the Pro edition.

Windows 11 Enterprise builds on Pro and is available only through Volume Licensing agreements. It adds features for large-scale IT management, such as AppLocker and DirectAccess, and is not sold as a single retail license. Windows 11 Pro for Workstations is a higher tier of Pro, designed for server-grade hardware with up to 4 CPUs and 6 TB of RAM, featuring ReFS (Resilient File System) and persistent memory support. For the vast majority of professionals and businesses, Windows 11 Pro is the perfect balance of advanced capability and value.

System requirements / compatibility

To ensure a smooth installation and optimal performance, your PC must meet the following minimum system requirements for Windows 11 Pro. Please note that these are the baseline requirements; a more powerful system will provide a better experience.

• Processor: 1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC).
• Memory (RAM): 4 GB minimum.
• Storage: 64 GB or larger storage device.
• System Firmware: UEFI, Secure Boot capable.
• TPM: Trusted Platform Module (TPM) version 2.0.
• Graphics Card: Compatible with DirectX 12 or later with WDDM 2.0 driver.
• Display: High definition (720p) display that is greater than 9” diagonally, 8 bits per colour channel.
• Internet Connectivity: Internet connectivity is required to perform updates and to download and take advantage of some features. A Microsoft account is required for some features.

This license supports both 32-bit and 64-bit architectures where supported by the product edition, though Windows 11 itself is 64-bit only. The product key is language-neutral and can activate installations in English, German, French, Dutch, and Polish. For the most accurate and up-to-date compatibility, particularly for specific business applications, we always recommend validating against the official Microsoft documentation for your hardware and software.

Installation and activation

Getting started with your new Windows 11 Pro license is a straightforward process designed for immediate access. After your payment is securely processed, your unique product key and comprehensive setup guide are delivered instantly by email. On average, this email arrives in under 60 seconds, allowing you to begin your installation without delay.

The activation guide provides clear, illustrated steps for two scenarios. If you are performing a clean installation, you will use the official Microsoft Media Creation Tool (link provided) to create a bootable USB drive, boot from it, and enter your new key when prompted. If you are upgrading an existing Windows 10 or 11 Home installation, the process is even simpler: you enter the new Pro key in the Activation settings menu, and Windows will unlock all Pro features in minutes, keeping your files and applications intact.

This is a Retail license, which grants you the flexibility to reinstall Windows on the same PC as many times as you need. Should you experience a hardware failure or choose to upgrade your computer's core components, a Retail license can often be transferred to a new device, a significant advantage over OEM licenses that are permanently bound to the first machine they are activated on. If you encounter any activation errors, our free multilingual technical support team is ready to assist you.

FAQ — frequently asked questions

Is this a subscription or a one-time purchase?

This is a permanent, one-time purchase license for Windows 11 Pro. You pay once and can use the software for the lifetime of your device. It is not a recurring subscription like Microsoft 365.

What is the difference between a Retail and an OEM license?

A Retail license, like this one, is the most flexible. It can be transferred to a new computer if you replace your old one, and it includes direct support from Microsoft. An OEM license is pre-installed by a manufacturer, is tied permanently to the first computer it's activated on, and cannot be legally transferred.

How fast do I get my license key?

Our delivery is instant and automated. On average, the email containing your product key and download guide arrives in your inbox within 60 seconds of a successful payment.

Absolutely. Every license sold by Lizensa is sourced directly from authorised European distributors. It is a 100% genuine Microsoft license, fully legal for use in all 27 EU member states, and comes with a full VAT invoice.

Can I reinstall or transfer this license to a new PC?

Yes. As a Retail license, you can reinstall Windows 11 Pro on the same PC unlimited times. If you buy a new PC, you can transfer this license to the new hardware, provided you remove it from the old device. This is a key advantage over OEM licenses.
