The lock screen provides security and takes more time to startup. Despite this, some users feel its waste to have a lock screen on the computer. If you want sign-up screen directly, then you have to disable the lock screen, which we can do by using Windows's Registry Editor.
Step 1: Using the keyboard, press the button Windows+R, type regedit and click enter.
Step 2: Here you are required to browse to the directory, HKEY_Local_MachineSoftwarePoliciesMicrosoftWindows.
Step 3: Right-click on the Windows directory and select New->Key to create a new one.
Step 4: Rename the new key as Personalization. On the new folder, right-click and select the New and DWORD (32-bit) Value.
Step 5: Rename the created new folder with NoLockScreen, change the value data to 1 and select OK. Now restart your computer and the lock screen will not be displayed anymore.
