Do you want to avoid using the lock screen to log in? There is a simple way to do this: first, open the Run command box. To do so, simply type the following into the Cortana/search box (next to the Start menu):
A User Accounts window will appear, and you'll need to select the account that will automatically login here. Enter the account's credentials and click OK.
After that, a new window called Automatically Sign-in will appear. Re-enter your password and click OK. Select 'Never' under the 'Require Sign-in' box in Sign-in options, then hit OK one last time.
