When you power up your Windows 10 PC, the lock screen also adds an additional keypress to the login process. The lock screen is the screen you see when you lock or restart your Windows 10 PC or when your PC locks automatically after you stop using it. You will need to dismiss the lock screen to be able to see the sign in screen and login to Windows 10. Users can dismiss the lock screen using touch, the keyboard, or by dragging it up with the mouse. These instructions will show you how to enable or disable the lock screen on Windows 10.
In order to get started, you must be signed in as an administrator to be able to make the necessary changes to your lock screen on Windows 10. Please note: If secure sign-in is enabled on your device and requires you to press the CTRL+ALT+DELETE keys simultaneously on the lock screen before signing in, you will not be able to complete any of these steps and the lock screen on your device cannot be disabled. Once you complete the following steps, Windows 10 will always go straight to the login prompt, skipping the lock screen permanently.
1. Open Registry Editor on Windows 10 by typing regedit in the search box. Click Yes when the User Account Control (UAC) box pops up to run the Registry Editor as an administrator.
2. In the Registry Editor, go to the following path: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsPersonalization
3. Create a New DWORD (32-bit) value by right-clicking in the right pane, selecting New, then DWORD (32-bit) Value and name the DWORD (32-bit) Value NoLockScreen.
4. Double-click NoLockScreen and change the hexadecimal value from 0 to 1. 
5. Click OK when you are finished and close the Registry Editor.
If you want, you can restart your computer, but the lock screen will already be disabled via the registry edit that you just made. Try pressing CTRL+ALT+DELETE simultaneously and choose to lock your PC to verify that the lock screen is permanently disabled.
From now on, your Windows 10 PC will bypass the lock screen completely and go directly to the login prompt. From there, you can enter your password, PIN, picture password, or use Windows Hello to login to your Windows 10 device. In the future, if you want to re-enable the lock screen n your Windows 10 PC, either delete the NoLockScreen DWORD value from the Registry Editor or set the NoLockScreen DWORD value to 0.
