To remove the lock screen entirely, so that locking is just a plain password prompt — and booting up goes straight to the same password prompt — just follow these very simple steps.

1. Hit the Start key, type gpedit.msc, and press Enter. This will open the Local Group Policy Editor.

2. Navigate to Computer Configuration > Administrative Templates > Control Panel > Personalization

3. Double click “Do not display the lock screen,” and select Enabled from the dialog that pops up. Click OK.

The change is immediate. Go ahead and press Win+L and admire your new, minimal lock screen.
