How to Open “Computer” with Windows Explorer

By default, Windows Explorer’s launch page is the Libraries directory. Clicking on the Explorer button on the taskbar also launches your Libraries directory. However, most of us would rather have My Computer as the launch directory. In order to do this type “explorer” into the Start Menu search field, locate the Windows Explorer shortcut and select properties from its right click context menu.
Change the target from “%SystemRoot%\explorer.exe” to “%SystemRoot%\explorer.exe /root,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}”.
Save the changes and you are done!

If you want to change the properties of the taskbar entry only, right click on the explorer button on the taskbar, right click on Windows Explorer (near the bottom of the jumplist) and select properties. Then change the target to “%SystemRoot%\explorer.exe /root,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}”
