Yes, the DLL needs to be registered in order for the OS to find it.  It is
the responsibility of the DLL to export a DllRegisterServer() function
(amongst a few others), which then sets up the necessary "InProcServer32"
value (and others) that tells the OS where your DLL is located when it needs
to find it.

You don't need to write your own application for that.  The OS already has
one - REGSVR32.

If you want to write your own, though, then simply load the DLL via the
LoadLibrary() function, use GetProcAddress() to find the exported
DllRegisterServer() and DllUnregisterServer() functions, and then call them
when needed.

No, because the Shell makes use of the Registry to know what it is supposed
to load and when.

Then you have to register/unregister your DLL when appropriate.

The alternative is to keep the DLL registered always, and then set up your
own Registry value separately that the DLL checks when called to determine
if it should actually do anything or just return immediately.
