Windows 7 is a popular operating system due to its intuitive UI (user interface), multitude of features and increased security compared to the previous Windows editions.

Nonetheless, users are constantly looking for more customization options within any OS they work with, and some of them might find Windows 7 Lock Screen Changer useful.

It needs to be mentioned from the get-go that the lock screen image is different than your desktop wallpaper and that you only see it when you lock your screen or you restart your PC.

As suggested by its name, the application works only with Windows 7 computers, so you should not try to customize your lock screen image if you are running a different operating system as it will not work.

Also, it is best to run the utility with administrative privileges, just to make sure no errors will be triggered.

The application comes with a minimalistic interface so that even novices can browse to the picture they want to use as their lock screen and apply it. However, you need to make sure that the graphic file you select meets some standards, as only JPEG images are supported, with a small size.

Once you have located the pic you prefer, you can preview it within Windows 7 Lock Screen Changer and apply it - if you do not want to restart your PC just to get a glimpse of the new image, you can simply lock your computer (press Ctrl+Alt+Del).

All in all, Windows 7 Lock Screen Changer can come in handy to all users who are looking for more customization for their PC, since replacing the desktop wallpaper or installing a new theme can be old news for most people.
