From desktop, right click on This PC or My PC icon.. Or from control panel go to the following settings –
Control Panel\System and Security\System
Click on the Advanced System Settings on the left. And from the pop up option click on Settings under Performance. Select Custom for visual effects and uncheck them all except for “Show thumbnail instead of icons“. Because if you stop thumbnail being shown, you will have difficulties while managing photos as they won’t show thumbnail unless you click on them.
Now you have turned of all the visual effects and unnecessary animations on Windows 10.
