What does Windows 11 Pro add over Windows 11 Home?
Pro adds tools for security, remote work and IT management that Home doesn't have. If you only browse, stream and use Office, Home is usually enough. If you store client files, work remotely or run virtual machines, Pro is the edition built for that.
| Feature | Windows 11 Home | Windows 11 Pro |
|---|---|---|
| BitLocker drive encryption | No (device encryption only on some PCs) | Yes |
| Remote Desktop host (connect to this PC) | No | Yes |
| Hyper-V virtual machines | No | Yes |
| Windows Sandbox | No | Yes |
| Group Policy editor | No | Yes |
| Join a domain or Microsoft Entra ID (Azure AD) | No | Yes |
Why BitLocker matters on a laptop
BitLocker encrypts the whole drive, so a lost or stolen laptop doesn't hand over your files. Without the recovery key, the data can't be read even if the drive is taken out and put in another computer. Before you turn it on, save the recovery key to your Microsoft account or print it.
Remote Desktop and Hyper-V for working from anywhere
With Pro, you can connect to your office PC from another device using Remote Desktop. Hyper-V lets you run a separate Windows or Linux system in a window on the same PC, which is useful for testing software or keeping work and personal tools apart.
What are the system requirements for Windows 11 Pro?
Windows 11 Pro needs a compatible 64-bit processor, 4 GB of RAM, 64 GB of storage, UEFI with Secure Boot, and TPM 2.0. These are Microsoft's minimums, and the same rules apply to every Windows 11 edition. Most PCs from the last few years meet them, but older machines often fail on the TPM 2.0 or processor check.
| Component | Minimum requirement |
|---|---|
| Processor | 1 GHz or faster, 2 or more cores, compatible 64-bit CPU or SoC |
| Memory (RAM) | 4 GB or more |
| Storage | 64 GB or more |
| System firmware | UEFI, Secure Boot capable |
| Security chip | TPM version 2.0 |
| Graphics | DirectX 12 compatible, WDDM 2.0 driver |
| Display | 720p (HD), larger than 9" diagonal |
| Internet | Needed for activation, updates and some features |
To check your own PC, run Microsoft's PC Health Check app or read the official Windows 11 requirements.
How do I activate Windows 11 Pro?
If Windows 11 is already installed, you enter the key in Settings. Upgrading from Home this way keeps all your files and apps. For a new PC or a fresh start, install Windows 11 first using Microsoft's official media, then enter the key.
- Open Settings → System → Activation.
- Select Change product key (on Home PCs, it's under "Upgrade your edition of Windows").
- Enter the 25-character key from your order email and select Next.
- If you're upgrading from Home, let the PC restart. The upgrade usually takes a few minutes.
- Go back to Activation and check that it says "Windows is activated".
A common issue we see is a key entered on the wrong edition. A Pro key won't activate Windows 11 Home directly. Use "Change product key" as above so Windows upgrades to Pro first.
Frequently asked questions
Can I upgrade from Windows 11 Home to Pro with this key?
Yes. Enter the key under Settings → System → Activation → Change product key. Windows upgrades to Pro in place, and your files, apps and settings stay where they are. You don't need to reinstall or download anything else.
Can I use this key to upgrade from Windows 10?
Upgrade the PC to Windows 11 first using Microsoft's free upgrade or installation media, then activate Pro with this key. The PC must meet the Windows 11 requirements above, including TPM 2.0 and Secure Boot.
Is this a subscription?
No. Windows 11 Pro is a one-time purchase for one PC, with no monthly or yearly fee. Security and feature updates come from Microsoft through Windows Update at no extra cost.
What happens if I replace my PC's motherboard?
Windows activation is tied to your PC's hardware. A major change like a new motherboard can cause Windows to report it's no longer activated. If you've linked your Microsoft account, the Activation troubleshooter can often reactivate it. If it doesn't, contact our support team with your order number.
