How to open files and folders with a single click

By default, clicking once on a file or folder in My Computer or Windows Explorer highlights it; you have to double click to open it. But if you're really lazy - er, efficiency-minded - and want to be able to open items with just one click, you can configure XP to do so. Here's how:

1. Click Start | My Computer
2. In the My Computer console, click Tools | Folder Options
3. Under "Click Items as Follows" at the bottom of the General tab, select "Single-click to open an item (point to select)
4. Click OK

Now you can save energy by eliminating dozens or hundreds of clicks per day!
