    Hello, Lawrence Hines.

    I had a friend download a copy of windows 11 on my Surface tablet...

    Please clarify:

    1. Was Windows 11 only downloaded on this device or was this OS installed on this device?
    2. If the OS was installed, then write which edition (Home, Professional, etc.) was installed initially and which edition is now.

    P.S. The information you receive will allow you to find out if you need to buy a license /key for this OS at all.

    If Windows 11 was installed on a device that does not already have an activated Windows 11 license for that edition, a valid product key or digital license is needed to activate it.

    Ways to get it:

    1. Buy a digital license in Windows
      • Open Start > Settings > System > Activation.
      • Select Go to Store or Open Store.
      • Purchase a Windows 11 digital license in Microsoft Store.
    2. Buy a product key from Microsoft online or an authorized retailer
      • If purchased digitally, the product key is typically in the confirmation email.
      • If purchased as a boxed copy, the product key is on the label or card inside the box.
    3. Check whether the Surface already has an embedded or existing license
      • On a new PC or device that came with Windows, the product key may be preinstalled, included with packaging, or on the Certificate of Authenticity (COA).
      • If Windows was previously activated on the device with a matching edition, activation may use a digital license instead of requiring a new key.

    If this is the first time Windows 11 is being activated on that Surface, or if a different edition was installed than the one previously licensed, a valid product key is required.
