After setting up Windows 10 PC with a local user account, Microsoft keeps pushing to switch to Microsoft account by occasionally displaying below screen during login. There is no obvious way to permanently disable the offer. Continue button takes you to the Microsoft account setup screen. Remind me later only temporarily dismissed the screen.
Let's finish setting up your device.
Your device needs to connect to a few more Microsoft services to help you work more easily and securely across all your devices. Select "Continue" to get started in just a few clicks.
To permanently disable this screen, log in to Windows, go to Settings > System > Notifications & Actions and under Notifications disable option: "Suggest ways I can finish setting up my device to get the most out of Windows". While you are there, you can also disable other 2 options that enable Microsoft to advertise its services in Windows.
Be aware that this option is only present in Windows 10 v2004 and later. If you are running an older version of Windows, you'll have to update it first.
