This feature is only available in Windows 7.
Using the "Logon Screen" feature, you can change the login screen (lock screen) background in Windows 7, that cannot be done through the personalization settings available in the system itself.
You can use any image files as backgrounds, just keep in mind that the selected image is reduced to a size not exceeding 250 KB. This is a technical requirement of Windows. Therefore, choose small images with an uncomplicated pattern, like our instances.
When you click on the "Find pictures" button, the section of the Desktop Lux website opens, where you can choose from thousands of images new backgrounds for your logon screen and download them to your computer.
