The advantage of logging into your Windows computer with your Microsoft account is that if you want to purchase an app from the Microsoft Store or IF you use OneDrive (not my first recommendation) you’re already logged in.
I know that MOST of you don’t purchase apps from the store. If you’re like me and log into your computer with a LOCAL account (meaning it doesn’t matter if your computer is online or not AND Microsoft doesn’t know each time you log onto your computer) then your Windows 10 computer will on occasion show you this little message in the corner…
The ONLY problem with your Microsoft account is that Microsoft can’t tell when you’re using your computer (for the most part.) So DON’T WORRY when you see this message, and don’t feel the need to create a Microsoft account to change how you log onto your computer. Just SMILE and say “no thank you Microsoft” the next time you see it.
