Download our Disable Logon Background Image on Windows 10 registry hack. Double-click the included “Disable Logon Background Image on Windows 10.reg” file to add the tweak to your registry. We’ve also included a .reg file that will undo the change, if you like — just double-click it.
If you’d like to do it yourself, open the Registry Editor and create a DWORD value named “DisableLogonBackgroundImage” under “HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System” with the value “00000001”.
