Use Single Click Everywhere

With single click, access folders and files on your hard disk is as easy as navigating the Web. You simple click an icon to open a program or document.

To start using single click

1. Click My Computer
2. In the Tools menu in Windows Explorer, click "Folder Options".
3. In the Click items as follows section, click "Single click to open an item (point to select)".
4. (Optional) My advise is choose the option "underline icons title only when I point at them" as well, so it won't show too many underline shortcut
