Sound Recorder/Volume Control

I've lost the Volume Control icon from my System Tray and Sound Recorder
from the Entertainment heading of my Start/Programs list.

I've tried re-installing via Add/Delete Programs but the App isn't displayed
there.

As for re-installing XP, I can't do that either because I have SP2 installed
and my XP Disc has SP1 and therefore believes my PC contains a newer version
and it shuts me down.

How do I get my Sound Recorder and Volume Control Apps back where they
belong?

TIA,

Terry
