The following tasks are frequently used to customize folders and some aspects of your desktop
Add Web content to your desktop
You can add Web content, such as a stock ticker or weather map, to your desktop.
Display links to common tasks in folders
You can display hyperlinks to common tasks in the left pane of your folder windows. The links provide quick access to file and folder management activities and other places on your computer, such as My Computer, Shared Documents, and My Network Places. Windows displays these links by default, so they may already be displayed in your folders. If they are not, you can use Folder Options to enable this feature.
Change the number of mouse clicks required to open items
Use one or two clicks to open files and folders, and specify when you want the items to be underlined.
Show hidden files and file name extensions
Certain files and folders are assigned the Hidden attribute by default. You can choose to display these hidden files and folders. You can also display file extensions for common file types, such as .txt or .htm.
