Windows 11 Pro: The Complete Guide to Features, Activation, and Where to Buy a Genuine Licence

Windows 11 Pro is Microsoft’s most powerful consumer operating system. It includes BitLocker encryption, Remote Desktop, Hyper-V virtualisation, and Group Policy controls that the Home edition simply doesn’t have. As of early 2026, nearly 3 in 4 Windows PCs worldwide now run Windows 11. If you want full features, proper security, and a system that’s truly activated, you need a genuine licence. You can grab one today for just €8.49 at operacinesistema.lt.

You’ve probably seen the “Activate Windows” watermark sitting in the corner of your screen. Or maybe you’re looking to upgrade from an older system and want to know if Windows 11 Pro is actually worth it. Either way, you’re in the right place.

Here’s something that might surprise you: according to Statcounter data from February 2026, Windows 11 now runs on 72.78% of all Windows PCs worldwide. That’s nearly 3 out of every 4 machines. The migration from Windows 10 has hit a tipping point, and the reason is simple: Windows 10 support ended in October 2025, and Windows 11 Pro is now the operating system serious users rely on.

This guide covers everything you need to know about Windows 11 Pro: what it is, what makes it better than Home, how to activate it, and exactly where to get a working licence without overpaying.

What Is Windows 11 Pro?

Windows 11 Pro is Microsoft’s premium desktop operating system, designed for power users, professionals, and small businesses. It includes all the features of Windows 11 Home, plus a set of advanced tools focused on security, remote access, and system management that aren’t available in the standard edition.

Think of it this way: Home is the car, Pro is the same car with four-wheel drive, a reinforced chassis, and an advanced security system included. The everyday drive feels the same. But when you need those extra capabilities, they’re there.

It launched on October 5, 2021, and has received continuous updates since. Microsoft confirmed in early 2026 that Windows 11 has now crossed one billion active users, making it the most widely used operating system on the planet.

What Are the Best Features of Windows 11 Pro?

Windows 11 Pro includes several exclusive features that aren’t available in Windows 11 Home: full BitLocker drive encryption, Remote Desktop hosting, Hyper-V virtualisation, Group Policy management, Azure Active Directory support, and Windows Sandbox. These tools are designed for users who need stronger security, remote access, or the ability to run multiple operating systems on one machine.

Here’s a plain-English breakdown of the most useful ones:

BitLocker Drive Encryption is the single biggest reason to choose Pro over Home. BitLocker encrypts your entire drive using AES encryption, so that if your laptop is ever lost or stolen, nobody can read your files without your password. Home only includes a limited “Device Encryption” feature. Pro gives you full, flexible, user-controlled encryption on any drive, internal or external.

Remote Desktop lets you connect to your PC from anywhere in the world. You could be at home and connect to your office desktop, access your files, and run your apps, just as if you were sitting in front of it. Windows 11 Home can only be a client (meaning it can connect to other machines) but it can’t host connections. Pro can do both.

Hyper-V is Microsoft’s built-in virtualisation tool. It lets you run a separate operating system, like Linux or an older version of Windows, inside a window on your desktop. Developers and IT professionals use it constantly for testing software in a safe environment. Windows Sandbox works alongside Hyper-V to let you open suspicious files or test new apps in a completely isolated space that resets every time you close it.

Group Policy gives you centralized control over settings across multiple computers. If you’re running a small business with several machines, this is how you enforce consistent configurations without touching each PC individually.

What Are the System Requirements for Windows 11 Pro?

Windows 11 Pro requires: a 1GHz or faster 64-bit processor with at least 2 cores, 4GB of RAM, 64GB of storage, a DirectX 12-compatible GPU, TPM 2.0, UEFI firmware with Secure Boot enabled, and a display of at least 720p resolution. These requirements are the same for both Home and Pro editions.

The most important of these, and the one that trips up most users, is TPM 2.0. TPM stands for Trusted Platform Module. It’s a security chip built into most modern motherboards, and it’s required by Microsoft to support BitLocker encryption and other security features.

Before you buy a licence or attempt an upgrade, it’s worth checking that your hardware meets these specs. If you’re unsure, our guide on how to install Windows 11 step by step walks you through it from start to finish.

Windows 11 Pro vs Windows 11 Home: What’s the Difference?

Windows 11 Pro includes everything in Home plus five major exclusive features: full BitLocker Drive Encryption, Remote Desktop hosting, Hyper-V virtualisation, Group Policy management, and the ability to join an Active Directory or Azure AD domain. The interface, performance, and gaming experience are identical between the two editions.

Here’s the honest summary: if you don’t know what BitLocker or Hyper-V are, you probably don’t need Pro. A casual user who browses the web, streams video, and uses Office will be perfectly happy with Home.

But if any of the following sounds like you, Pro is the right choice:

• You use a laptop and want your data protected if it’s ever stolen (BitLocker)
• You work remotely and need to access your office PC from home (Remote Desktop)
• You’re a developer or IT professional who runs virtual machines (Hyper-V, Sandbox)
• You manage multiple computers in a small business (Group Policy, Azure AD)
• You want to create a local account without a Microsoft account during setup (Pro only)

For a deeper look at every difference, check out our full breakdown of features only available in Windows 11 Pro.

There’s one more thing worth mentioning: Pro also supports up to 2TB of RAM, compared to Home’s 128GB ceiling. For most people that’s irrelevant. For workstation users, it matters a lot.

How Do You Activate Windows 11 Pro?

Activating Windows 11 Pro takes about two minutes. Go to Cài đặt, then Hệ thống, then Kích hoạt. Click “Change product key”, enter your 25-character licence key, and click Tiếp theo. Windows will verify the key with Microsoft’s servers and confirm activation instantly.

That’s really all there is to it. No extra tools. No complicated steps. Just a genuine key, a working internet connection, and you’re done.

If activation fails, there are three common reasons: the key has already been used on another device, you’ve entered it incorrectly, or there’s a temporary connection issue. Our guide on how to activate Windows 11 Pro without errors covers every error message and how to fix it.

What happens if you don’t activate? The “Activate Windows” watermark stays on your desktop permanently. You lose access to personalisation settings (themes, backgrounds, colours). Some features are restricted, and you won’t get the full benefit of security updates. In short, you’ve installed the OS but you can’t properly use it.

Is Windows 11 Pro Worth It in 2026?

Yes. Windows 11 Pro is absolutely worth it in 2026, for two simple reasons. First, Microsoft ended support for Windows 10 in October 2025, which means no more free security patches for Windows 10 users. Second, the features in Pro directly address the biggest risks most PC users face: data theft, remote access needs, and malware.

The numbers back this up. Windows 11 went from 50.73% market share in December 2025 to 72.78% by February 2026, a 22-point jump in just two months. That’s not coincidence. That’s millions of people realising that sticking with an unsupported OS is a real security risk.

There’s also the performance angle. Windows Central reports that Pro ships with features like Administrator Protection and Quick Machine Recovery (added in 2025) that actively protect against attacks even when something goes wrong at the system level.

For home users, the protection is real too. BitLocker alone can be the difference between a stolen laptop being an inconvenience and a full data breach.

If you’re comparing prices: Microsoft’s official retail price for Windows 11 Pro is $199.99. You can get the exact same genuine licence from us for just €8.49. That’s a saving of over 95%.

Where Can You Get a Genuine Windows 11 Pro Licence for the Best Price?

A genuine Windows 11 Pro licence key is a 25-character activation code that Microsoft’s servers recognise as valid, tied to a real retail or OEM licence. It activates your copy of Windows permanently, with no time limits and no need to renew. The key is sent to your email instantly after purchase, and it works in all countries and languages.

There are only two things you should avoid when buying a licence key. The first is pirated or “cracked” software. It won’t activate properly, it often carries malware, and it leaves your PC permanently at risk. The second is randomly generated “free keys” that get passed around online. Our own post on free Windows 11 Pro keys explains exactly why free keys never work: they’re either placeholder keys from Microsoft’s own test builds, already-used OEM keys, or simply made-up strings of characters. None of them will activate your copy of Windows.

What you want is a genuine digital licence key from a trusted seller. That’s what we sell at operacinesistema.lt.
