Linking Windows license with MS account - What does it do?

There's a nice and practical workaround for this.

When signed in to Windows with your local account, open any native Windows UWP app. I often use Weather app for this. Sign in to app with a Microsoft account (screenshots from Weather app):





When you have entered your MS account email, password and in case you are using two-step authentication, the verification code, click Next to add this MS account to Windows although still keeping your local account as a sign-in account:





This does not switch your Windows 10 local account to a Microsoft account. You will continue signing in to Windows with your a local account but you have now set Windows to automatically sign in to all Microsoft apps with the MS account email. Activation will now be connected to your MS account:





This allows you to transfer the license after hardware change.
