4. In personalization, the wallpaper change interval is set to 10 seconds, the wallpaper switch time is set to 9000 milliseconds, and the CPU usage of the two processes Dwm.exe and Explorer.exe through Resource Monitor will not exceed 4%, which is normal and does not add additional burden to the system.

This is the way the Win7 system adjusts the speed of the desktop wallpaper switch. However, we recommend that you adjust the switch wallpaper time is not too long, because the switch effect of too long time can even deceive our eyes, too natural, completely do not know if there has been a switch.
