How to Use Store without Switching to Microsoft Account in Windows 10
There are several reasons why users will continue using local accounts in addition to Microsoft accounts. In my case for instance I like to set up Windows 10 PC with a local adminitrator account and add my my Microsoft account as a standard account. Other users might have other reasons to use local accounts.
Whatever reason you have to use a local account, if you want to use apps from Windows Store you will need a Microsoft account. If you don't have one you can create a new Microsoft account.
However, to download and install apps from Windows Store you don't have to switch to a Microsoft account. You can continue using a local account to sign in to Windows, and use the Microsoft account only to sign in to Windows Store to download apps.
