Windows 11 Pro Retail is the full, transferable licence of Microsoft’s professional-grade operating system.

How do I install Windows 11 Pro?

To install Windows 11 Pro, boot your PC from the installation media (USB drive or ISO), select your language and edition, accept the licence terms, and choose the drive on which to install. When prompted, select I don’t have a product key — you will enter your key during or after installation. Ensure your hardware meets the minimum requirements: a 64-bit processor with at least 2 cores, 4 GB RAM, 64 GB storage, TPM 2.0, and UEFI Secure Boot.

How do I activate Windows 11 Pro Retail?

Once Windows 11 Pro is installed, activation is straightforward:

1. Go to Settings → System → Activation.

2. Click Change product key and enter the 25-character key you received by email.

3. Click Next and follow the prompts. Windows will contact Microsoft’s activation servers and activate automatically.

An internet connection is required for online activation. If you encounter an error, use the built-in Activation Troubleshooter (Settings → System → Activation → Troubleshoot) or contact our support team for assistance.

What should I do if my Windows 11 Pro key is not working?

First, double-check that the key has been entered exactly as shown in your email (no extra spaces or mixed-up characters). Common activation errors can also result from a mismatch between the key edition and the Windows edition installed. If the problem persists, please contact Shop Key Online’s support team — we will verify your key and resolve the issue. If we are unable to do so, you are covered by our 100% money-back guarantee.

Can I use my Windows 11 Pro Retail key on more than one PC?

Each licence activates one device. Once activated, it is tied to that machine for its lifetime — you will not need to re-purchase if you reinstall on the same device. If you need to transfer the licence to a different computer, a new key will be required. For bulk purchases, our 2-PC minimum order Windows 11 Professional Retail offers excellent value.

Is this a genuine, lifetime licence?

Yes. Windows 11 Pro Retail keys sold by Shop Key Online are 100% genuine Microsoft licences. Once activated, your licence is valid for the lifetime of the installed device — there are no recurring fees or subscription charges.

Can I upgrade from Windows 10 Pro to Windows 11 Pro using this key?

Yes. If your hardware meets the Windows 11 minimum requirements, you can perform an in-place upgrade from Windows 10. Run the Windows 11 Installation Assistant on your existing Windows 10 machine and enter your new product key when prompted. Alternatively, see our Windows 10 Pro Retail listing if you prefer to stay on Windows 10.

What are the minimum system requirements for Windows 11 Pro?

Your PC must meet the following minimum specifications to run Windows 11 Pro:

• Processor: 1 GHz or faster, 2+ cores, 64-bit compatible or SoC

• RAM: 4 GB (8 GB recommended)

• Storage: 64 GB or more

• Firmware: UEFI with Secure Boot enabled

• TPM: Trusted Platform Module (TPM) 2.0

• Graphics: DirectX 12 compatible / WDDM 2.x driver

• Display: 720p (HD) display, 9″ or larger, 8-bit colour

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

A Retail licence is tied to you as the purchaser and can be transferred to a new PC if needed. An OEM licence is permanently bound to the first machine on which it is activated and cannot be transferred. For users who may upgrade their hardware in the future, a Windows 11 Pro Retail licence offers greater flexibility. If an OEM licence suits your needs, see our Windows 11 Pro OEM listing.
