How to Upgrade Windows 10 Home to Pro via the Windows Store

If you haven't paid anything for the upgrade yet, and no one has handed you a copy of Pro, the most straightforward way to upgrade is using the Windows Store. In order to upgrade, take the following steps:

  1. First, make sure your PC doesn't have any pending updates.

Upgrade From Windows 10 Home to Pro via a License Key/Digital License

If you do have a copy of Windows 10 Pro, or maybe you found a retail copy of the upgrade for less than Microsoft charges, you'll have a product key (alternately called a license key) that enables Windows 10 Pro. You'll need it to replace your current license key. To do so:

  1. Make sure you're up to date on any Windows Updates.

  2. Navigate again to Start Menu > Settings > Updates and Security > Activation.

    Windows 10 Activation
  3. Under Activation, select Change product key. The Product Key window will open.

  4. Enter the 25-digit Windows Pro Product Key.

  5. Select Next. If your key is correct, the upgrade will start, and you'll soon get a message that Windows has been upgraded.

If you installed Windows 10 Home manually, you have the option to move the Home license elsewhere and install the Pro version in its place. Our FAQ on product keys will tell you everything you need to know about moving Windows licenses between machines.

How to Transfer Your Windows 10 Pro Upgrade

Since you had a full operating system before this upgrade, you can remove it from its current machine and use it on another. You're effectively reinstalling your original license, which will make the upgrade available again. If you need to do this:

Do this while you're online so that Microsoft can register that you removed the Pro upgrade.

  1. Look at the bottom of your Windows laptop, or on the top/side of a desktop tower. There might be a sticker there showing your original Windows product key; alternatively, it might be in the manuals and other material that came in your PC's box.

  2. Enter the key in the Change product key dialog as noted above, and you'll effectively "downgrade" to your old Home license.
