Microsoft seems to be under the impression that change is good and will not confuse users of a previous versions of their Windows operating system. It is interesting that they decided to change on elementary function in Windows Vista if you compare it to Windows XP: the Add/Remove Windows Components.
If you go into the Control Panel in Windows Vista you will not find Add / Remove Programs like in Windows XP and there is also no SYSOC.INF file where you can remove the HIDE parameter to add more windows components to the Add / Remove Programs menu.
The function in Windows Vista is called Turn Windows Features on or off and is available in the Programs and Features menu. There is however a huge difference. You might have noticed the on or off phrase and that is exactly what is happening. The component is not uninstalled and still on the hard drive if you select to turn a feature off.
