The core concept of UMWP Autochanger is sets. Basically sets are folders on your computer where the tool will search for JPEG/PNG/BMP/GIF files up to 3 levels deep.

Once configured the tool will choose a random set among all activated set, then choose one image file for each monitor. Finally the final wallpaper is built with these files and sended to Windows desktop manager.

The wallpaper is updated periodically, by default every 60 seconds (configurable).


In Configuration ‣ Options menu you can configure the update delay, the shortcuts and some other options.

Additionally you can export and import the configuration as a XML file, usefull if you plan the reset your system !

As we already seen, sets state can be changed in the main window. UMWP Autochanger also provides two mechanisms to quickly change the active set.

The first one is the Quick change menu available when you right-click on the system tray icon.

The second one are the keyboard shortcuts. Shortcuts are keys combinations you assign to specific sets or actions.

First of all you have to activate the feature in the main Options window, you can also configure Refresh, Hide/Show and Start/Pause shortcuts in this window.

The sets shortcuts are configured in their respective properties window. Many sets can have the same shortcut, thus they will be activated together, but actions shortcuts must be unique.

Warning: shortcuts are registered globally on the operating system, that means they can cause interferences with other softwares, so make sure the shortcuts you choose are not already used.


The password lock can be used to prevent unwanted modification of the configuration and activation of sets.

The lock has two modes:

  • Lock everything: when locked, nothing can be done in the application without entering the password. The sets list is blurred out.
  • Lock sets: only some specific sets require the password in order to be activated.

In both modes, the password is always requested to enter the options.

The Custom style can be used to generate more or less random patchwork wallpapers. You can choose the size of the grid, the prefered range of tiles size and the color and size of the border and the shadow.

This mode also has a special Per folder mode (only available in random mode) in which all tiles are choosen inside a single sub-folder of the set.
