When clicking on the Windows Explorer shortcut on the Windows Taskbar, by default, it will open up the "Libraries" folder. If you prefer to open up "My Computer", change the Windows Explorer shortcut "Target" to any one of the following:
%windir%\explorer.exe /e,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}
%SystemRoot%\explorer.exe /e,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}
