I recently purchased a Windows 11 Pro key from the Microsoft store and added to my laptop. I now want to transfer to a different laptop but when I add the key on new one it says already exists on old one. How do I remove from old one? My new laptop is currently set to Windows 11 home as was the old one before I purchased the key and upgraded it.

Thank you for all comments. I could not work this out and was disappointed to have such trouble getting through to the Microsoft store for help with this. In the end I had to get an IT expert, support IT company, do manage the swapover.

    Welcome to Microsoft Q&A!

    Thank you for taking the time to explain what has been happening.

    Based on your description, the key point is how Windows 11 Pro was originally activated. Windows activation can use either a digital license or a product key, and the reactivation process depends on which activation method applies. A digital license is associated with the device’s hardware.

    • The possible cause

    Your new laptop is currently running Windows 11 Home, while the license you want to use is for Windows 11 Pro. The Windows edition must remain the same for a digital license or product key to reactivate. In other words, a Windows 11 Pro license needs Windows 11 Pro as the corresponding edition.

    Regarding your concern about the Microsoft account, it is important to distinguish between the two activation methods. If you have a digital license, Microsoft requires the associated Microsoft account to be linked to that digital license in order to reactivate Windows through the Activation troubleshooter.

    • Recommendation

    On the new laptop, open Settings > System > Activation and check the activation status and Windows edition.

    If you are reactivating a digital license, use Settings > System > Activation > Troubleshoot, select I changed hardware on this device recently, and then sign in with the Microsoft account that was linked to the Windows 11 digital license. Select the device you are currently using and then select Activate.

    Currently, there is no documented requirement in this process to manually remove the product key from the old laptop first. Microsoft’s reactivation guidance instead focuses on using the digital license associated with the Microsoft account or, if Windows was originally activated with a product key, entering that same product key again.

    After completing the reactivation process, return to Settings > System > Activation and verify that the correct Windows edition and activation status are displayed.

    If the Activation troubleshooter cannot locate or reactivate the license, I recommend contacting Microsoft Support rather than purchasing another Windows 11 Pro license. They can verify the Store purchase and activation entitlement in a way that Microsoft Q&A cannot.

    A Windows 11 Pro upgrade purchased through Microsoft Store is typically a digital license tied to the Microsoft account used for the purchase, not a reusable product key to manually enter on the new laptop.

    For this scenario, the new laptop must already have Windows 11 Home activated first, because the Pro purchase is an upgrade from Home to Pro.

    Use this process:

    1. On the new laptop, confirm Windows 11 Home is activated:
      • Go to Start > Settings > System > Activation.
    2. On the new laptop, sign in with the same Microsoft account that was used to buy the Windows 11 Pro upgrade from Microsoft Store.
    3. On the new laptop, open:
      • Start > Settings > System > Activation
      • Run the Activation troubleshooter
      • Choose the hardware change option
      • When prompted, select the old laptop as the device currently using the license
      • Then select the new laptop to activate it
    4. If the new laptop is still on Home and does not switch to Pro automatically, first upgrade the edition on the new laptop:
      • Go to Start > Settings > System > Activation > Change product key
      • Enter a Pro key to move the device to the Pro edition, then complete activation

    Important points:

    • There is no documented step here to “remove” the Store-purchased Pro upgrade from the old laptop first.
    • Microsoft Store purchases of Windows 11 Pro are described as using a digital license associated with the purchasing Microsoft account.
    • The old and new laptops both being originally Windows 11 Home matches the supported upgrade scenario.
    • If the license and installed edition do not match, Windows will not activate.

    If the old laptop is being sold, reinstalling it back to Windows 11 Home is commonly used before transfer, but the supported activation path shown here is the Activation troubleshooter with the Microsoft account-linked digital license.
