Where can I find a digital license for Windows 10 Pro?

Hello there! I am Charity, I'm an Independent Advisor. I'm glad to help you today!

Thank you for the information. A digital license for Windows 10 does not include a product key that you can view in the same way as a traditional product key. Instead, the digital license is tied to your hardware and Microsoft account.

Open Settings by pressing Windows + I.

Go to Update & Security.

Select Activation from the left sidebar.

Here, you will see the activation status of your Windows. If it says "Windows is activated with a digital license" or "Windows is activated with a digital license linked to your Microsoft account," it means your Windows is activated using a digital license.

If your Windows was activated using a retail key or a key provided by the manufacturer, you may proceed with the steps below.

Open Command Prompt as Administrator:

Press Windows + X to open the Power User menu.

Select Command Prompt (Admin) or Windows PowerShell (Admin).

In the Command Prompt window, type the following command and press Enter:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

Please keep me know if this worked for you.

Kind Regards,

Charity

I I sent the Windows 10 Home system update to a store and updated it to 10 Pro, but I changed my Microsoft account and it does not accept activation.

Just want to confirm, you physically took your computer to a store and they upgraded it to a windows 10 pro?

Yes

Y I hope to respond as quickly as possible

Thank you for the confirmation. I would highly suggest to contact the store you sent it from if they have used their own product key as they are the one who changed your version to Pro.
