By default minimize, maximize and close buttons are present on the right side of a window or an application. But if you don’t like the position or just wish to move the buttons to some other position, then give this a try.
LeftSider is a freeware tool that can move or shift the “Minimize, Maximize and Close buttons” to the left side of the window or an application. You just need to download the tool, and run the exe downloaded. The tool is very small in size and doesn’t require any installation.
If the buttons don’t come on the left then just refresh the system or reopen the window and if you just want to exit from the tool then end the process from the task manager.
