Return to a locked Windows 10 device and you’ll see a pretty picture. That’s nice, but it’s a needless obstacle in the way of logging in. If you’re as impatient as we are, disable the lock screen by searching the Start Menu for regedit, and running the Registry editor.
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows. If you don’t already see a key named ‘Personalization’, select the Windows key, right-click it, choose New>Key and rename this new key to Personalization (sic). Right-click the Personalization key, choose New again then select DWORD (32-bit) Value. Select New Value #1 in the right-hand pane and use F2 to rename it NoLockScreen, then double-click it, change the value data to 1 and click OK. After a reboot, the lock screen will be gone.
