If you're using a Windows 10 device, you may have signed in without using your Microsoft account. When you follow the steps below, you'll be able to see which account you're currently using. To sync your settings and Microsoft Store purchases across all your devices, you'll need to sign in with your Microsoft account.
Select the Start button, then select Settings > Accounts > Your info(in some versions, it may be under Email & accounts instead).
Select Sign in with a Microsoft account instead. You'll see this link only if you're using a local account. Note that if you see Sign in with a local account instead, you're already using your Microsoft account.
Follow the prompts to switch to your Microsoft account.
