Ok, with the Regsvr32 command I can register and un-register DLLs.

But do I have to reboot to get this registration active ?

I registered a specific context menu DLL but it is not visible after registration.

Is there a way to ask from command line (or from batch script file) if a DLL is already registered?

I would have expect such a function in Regsvr32 itself similar to


RegSvr32 /check mycontextmenu.dll
if errorlevel=1
Echo DLL already registered
else
Echo DLL not registered


But unfortunately this is not the case. Are there any other command line commands which check the registration ?
