Changing the picture displayed when you log into your system is not an option Windows OS is ready for, but Logon Screen has been created for exactly this purpose. Logon Screen is one way to easily modify the background of the logon screen.
Find the true last logon time for every user and computer account. Clean up your Active Directory by easily identifying unused or obsolete user and computer accounts by identifying their true last logon time and account status.
With InstantLogonChanger always have your Windows 7 logon background the same as your Desktop wallpaper or set it to any other image or color without any security prompts or changing system files.
