On private computers that are only used by one user, it really makes no sense to have to enter a password every time you startup. Good thing Windows 10 offers a relatively well-hidden feature for this. Use the Windows+R hotkey to open the Run window, type “netplwiz” and confirm with entering. In the User Accounts window that now opens, bring the Users tab to the front, uncheck the You must enter a password and username to use the computer before you can use the computer option, and click OK.
