Thank you for the information.
Click on the Start menu and select the Settings icon (gear icon).
In the Settings window, click on System.
Scroll down the left-hand side menu and click on About.
In the About section, look for the Windows specifications header. Here, you will see information about your Windows edition, including whether it is Windows 10 Home or Windows 10 Pro.
If it did succeeded in upgrading to Windows 10 pro, it should say pro. If it says Windows 10 Home, it will state it.
Please note that If you have a Windows 10 Home key but want to upgrade to Windows 10 Pro, you will need to purchase a Windows 10 Pro license. The Windows 10 Home key cannot be used to upgrade to Windows 10 Pro, hence the main reason why I suggest that you contact the store that upgraded your computer to pro for further instructions on what method they have upgraded your computer to pro.
