On my Vista laptop:
When I go to Control Panel > Sound > Recording, and double click on the Microphone in the recording device list, the "Microphone Properties" window opens. This window has 3 visible tabs: General, Levels and Advanced. The "Listen" tab is not available. How do I enable it?
Sound Card: Conexant High Definition SmartAudio HD2

Like the ability for 'stereo mix' to be supported as an input this is something that has to be enabled in the sound controller hardware.
Your drivers would need to expose this ability to Windows for it to present you with those options.
Thus either you need to update your drivers (the latest from HP is probably NOT the latest/most complete driver set for your card), or simply your card does not support this feature.
