There are some components in the Add/Remove applet in the Control Panel which are hidden in the different versions of Windows 2000/XP (Like the Games).

To unhide these components do the following :

1. Find the file SYSOC.INF which usually resides in C:\WINNT\INF
2. Make a backup of the file
3. Edit the file with a text editor like notepad
4. Remove every occurrence of "HIDE" (Use Replace...)
5. Save and exit and now the Add/Remove applet will show more options for the Windows Components
