This is probably the same line of thought that convinced Dario Volaric to create a back to basics edition of this Wallpaper Shifter application. This will probably appeal to many users who are looking for a lightweight wallpaper changer. The application picks a random wallpaper from a directory selected by the user and sets it as the active Windows wallpaper.

Once that has been done it closes down which means that it will not use any system resources from that point on. The application was designed to run during system startup but it can also be run when executed while Windows is running.

It comes with a few options to change the scale mode (automatic, crop, fit, center) and the background (default, blur, edge repeat) but that’s it. If you are looking for a one time a session wallpaper changer then this might be exactly what you are looking for.
