17.Display the Sharing Tab in Folder Properties

In Windows 2000, getting to the Sharing options for a folder was simple: Just right-click, choose Properties, and you'd see a Sharing tab. In Windows XP, this feature is missing by default, but you can make the system display the Sharing tab if desired. Simply open up Folder Options (My Computer, then Tools, Folder Options) and navigate to the View tab. In the Advanced Settings section, scroll down to the bottom and uncheck Use simple file sharing (Recommended), a Mickey Mouse feature if there ever was one. Now share your folders on the LAN as you would in Windows 2000.

14. Remove the Shared Documents folders from My Computer

One of the most annoying things about the new Windows XP user interface is that Microsoft saw fit to provide links to all of the Shared Documents folders on your system, right at the top of the My Computer window. I can't imagine why this would be the default, even in a shared PC environment at home, but what's even more annoying is that you cannot change this behavior through the shell: Those icons are stuck there and you have to live with it.
Until now, that is.
Simply fire up the Registry Editor and navigate to the following key (To open the Registry Editor simply type 'regedit' on Run window): HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ My Computer \ NameSpace \ DelegateFolders
You'll see a sub-key named {59031a47-3f72-44a7-89c5-5595fe6b30ee}. If you delete this, all of the Shared Documents folders (which are normally under the group called "Other Files Stored on This Computer") will be gone.
You do not need to reboot your system to see the change.
