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

Windows 11 Pro is Microsoft’s most powerful consumer operating system. It includes BitLocker encryption, Remote Desktop, Hyper-V virtualization, and Group Policy controls that the Home edition simply does not have. As of early 2026, nearly 3 out of 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 license. You can get one today for just €8.49 at operacinesistema.lt.

You’ve probably seen the “Activate Windows” watermark 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 It's 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 reached a tipping point, and the reason is simple: support for Windows 10 ended in October 2025, and Windows 11 Pro is now the operating system that 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 valid license 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 are not available in the standard edition.

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

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

What Are the Best Features of Windows 11 Pro?

Windows 11 Pro includes several exclusive features not available in Windows 11 Home: full BitLocker drive encryption, Remote Desktop hosting, Hyper-V virtualization, 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 a single machine.

Here’s a plain-language 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, no one can access your files without your password. The Home plan includes only a limited “Device Encryption” feature. The Pro plan gives you full, flexible, user-controlled encryption on any drive, whether 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 right in front of it. Windows 11 Home can only be a client (meaning it can connect to other machines) but it cannot host connections. The Pro version can do both.

Hyper-V from Microsoft's built-in virtualization tool. It allows you to run a separate operating system, such as Linux or an older version of Windows, inside a window on your desktop. Developers and IT professionals use it constantly to test 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 environment that resets every time you close it.

Group Policy gives you centralized control over settings across multiple computers. If you run a small business with several machines, this is how you ensure consistent configurations without having to access each PC individually.

What Are the System Requirements for Windows 11 Pro?

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

The most important of these, and the one that confuses most users, is TPM 2.0. TPM stands for Trusted Platform Module. It is a security chip built into most modern motherboards, and Microsoft requires support for BitLocker encryption and other security features.

Before you purchase a license or attempt an upgrade, it’s a good idea to check that your hardware meets these specifications. If you’re unsure, our guide on How to Install Windows 11 Step by Step guides you through the process from start to finish.

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

Windows 11 Pro includes everything in the Home edition plus five major exclusive features: full BitLocker Drive Encryption, Remote Desktop hosting, Hyper-V virtualization, 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 the Pro version. A casual user who browses the web, streams video, and uses Office will be perfectly happy with Home.

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

• You use a laptop and want to keep your data safe if it is ever stolen (BitLocker)
• You work remotely and need to access your office computer 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 more in-depth look at each difference, check out our full breakdown of features available only in Windows 11 Pro.

There’s one more thing worth mentioning: Pro also supports up to 2TB of RAM, compared to Home’s 128GB limit. 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 Settings, then System, then Activation. Click “Change product key”, enter your 25-character license key, and click Next. 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 entered it incorrectly, or there is 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 remains on your desktop permanently. You lose access to personalization settings (themes, backgrounds, colors). Some features are restricted, and you won’t get the full benefit of security updates. In short, you’ve installed the operating system but can’t use it properly.

Is Windows 11 Pro Worth It in 2026?

Yes. Windows 11 Pro is definitely 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 support this. Windows 11's market share rose from 50.73% in December 2025 to 72.78% by February 2026, a 22-point jump in just two months. That’s no coincidence. It’s millions of people realizing that sticking with an unsupported OS is a real security risk.

There’s also the performance aspect. Windows Central reports Pro comes with features such as 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, this protection is real as well. BitLocker alone can be the difference between a stolen laptop being a mere inconvenience and a full-scale 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 license from us for just €8.49. That’s a savings of over 95%.

Where Can You Get a Genuine Windows 11 Pro License at the Best Price?

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

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