Logitech and its damned LVUSBSta.sys driver

I've bought a Logitech STX QuickCam Communicate STX webcam - nothing sophisticated - just needed a simple, good quality webcam to be used in Skype chats.

The useful App Paths registry key

Yesterday on the Italian Delphi newsgroup run by Marco Cantù, Delphi&Dintorni, appeared a post asking how to load BPLs without writing them in the system directory or in the application directory.
I suggested to use the "App paths" registry key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths], but while looking for a reference for its proper use I didn't find a complete one, even on MSDN. It looks to be poorly documented, yet it's a very useful key.
