    Run virtual machines and test software in an isolated window.

  • Group Policy

    Set and lock system rules on the PC.

    Sign in with a work or school directory account.

  • Everything in Home

    Windows Hello, Microsoft Defender Antivirus, Snap layouts and the rest.

Read the setup guide

  1. Confirm the PC is compatible

    Run Microsoft’s PC Health Check app. Back up your files before changing the operating system.

  2. Check your current edition

    Open Settings, System, About. If the PC already runs Windows 11 Home, the Pro key switches it to Pro. If it runs Windows 10, upgrade to Windows 11 first with the installer from Microsoft’s Windows 11 download page.

  3. Enter your product key

    Go to Settings, System, Activation, choose Change product key and type the key from your email.

  4. Confirm activation

    The Activation page shows Windows 11 Pro as active once the key is accepted. A restart may be needed.

Windows 11 Pro or Home

Both editions look and work the same day to day. Pro adds security and management features that small businesses and remote workers tend to need.

Product keys and licensing

What you are buying, in plain terms.

  • A product key is what you type in to activate the software. Your right to use the software comes from the Microsoft Software License Terms shown during setup, and those terms govern how it may be used.

  • One key activates Windows 11 Pro on one PC. We cannot promise that a key will activate again after a hardware change or a move to a different PC.

  • Home and Pro keys are not interchangeable: a Pro key activates Pro only.

  • Software Key Source is an independent business. Microsoft does not endorse or sponsor this offer.

Questions about Windows 11 Pro

More answers are in the help center.

Open the help center
Do I need Pro or Home?

Choose Pro if you need BitLocker drive encryption, want to connect to this PC with Remote Desktop, run virtual machines, or join a work domain. For everyday work, browsing and entertainment, Home is enough.

Can I upgrade from Windows 11 Home with this key?

Yes. Open Settings, System, Activation, choose Change product key and enter the Pro key. Windows switches the edition and keeps your files and apps.

Will it work on my older PC?

Only if the PC meets Microsoft’s Windows 11 requirements, including TPM 2.0 and Secure Boot. Run PC Health Check before you buy.

Is Office included?

No. Windows 11 is the operating system. Office apps are a separate product.
