I searched it up for you, no idea if this works: To disable the "Make account" and "Remind me in 3 days" prompt on Microsoft, navigate to your Windows settings, then go to System > Notifications & actions; within the "Notifications" section, look for options related to "Suggest ways to finish setting up your device" or similar wording and toggle them off to prevent these reminders from appearing.
