As you know, each one of the Windows 10 versions is priced differently and one of the considered more expensive compared to the Windows 10 Home version is the Windows10 Pro. The good thing is, Microsoft allows its users to upgrade from the Windows 10 Home version to the Windows 10 Pro version at a reasonable cost instead of buying the entire license again.
However, upgrading your Windows 10 computer is not always that easy and you might encounter some errors along the way. One of the reported errors you could encounter is an error message that says, “Something happened, and we couldn’t start the upgrade”. This kind of problem is due to the problems with the Microsoft Store or the key authorization and to fix it, there are several options you can check out. You can try to run the built-in troubleshooters such as the Windows Update troubleshooter, Windows Store Apps troubleshooter, or Microsoft Accounts troubleshooter. You could also try to reset the Windows Store cache or re-register the Windows Store app. For more details, refer to each one of the given options below.
Option 1 – Try to run the Microsoft Accounts troubleshooter
