[Add to Startup] /
[Remove from Startup]

This button let Wallpaper Changer start up with Windows. This is a dynamic button (it changes), if you have already installed Wallpaper Changer by pressing the [Add to Startup] button. The button [Remove from Startup] will show.

When [Add To Startup] button is pressed, Wallpaper Changer will add itself in the windows registry and autostart when the user has logged in.

When the [Remove from Startup] button is pressed Wallpaper Changer removes itself from startup and will not change wallpaper after that.

This function will "REMOVE" Wallpaper Changer from your WINDOWS STARTUP. It will NOT remove any files. Wallpaper Changer is one single .exe file and some documentation files. To uninstall, simply remove all the file you downloaded and nothing will be left over in the system. 

But, why you should uninstall Wallpaper Changer ? ;)

[x] Use Tray Icon to

Use this option to decide whether to display a list of common functions (right click) or change your wallpaper when you click on the Wallpaper Changer in your System Tray (by the clock in the taskbar). I recommend to use always a tray icon, however if you must save tray space on you laptop, you can disable the icon. But, be careful with disabling, you can only Wallpaper Changer bring to foreground, if you start it again (the program will detect and call the current running instance) or you use the global hot key [SHIFT]+[CTRL]+[ALT]+[F5] !

If you decide to use a icon you can choose what Wallpaper Changer should do, when you double click on it.
