Windows 7: Why Are DCOM Launcher & RPC Call Set On Automatic & Grayed Out

Why Are DCOM Launcher & RPC Call Set On Automatic & Grayed Out

Many think these two services are huge security risks. I have no need for either one, but I can't set them to manual or disable because they are grayed out.
The associated port (port 135) is set never to acknowledge any request.
I would like to set both services to manual.

you said " I have no need for either one"---without RPC Call there are a lot of things that will fail to function--check the 'Dependencies' tab to see the list of affected items

I believe there is more than one RPC. I'm specifically speaking of the RPC tied directly to DCOM Launcher.
MS issued a patch to plug the security hole several years ago.
I'm just curious why the DCOM, and associated RPC, are greyed out in Win 7 HP.

I do not think that you understand what these two services do or you would not make such a claim. Don't be fooled by the term "Remote". These services allow the operating system's sub-systems to talk to each other :-)

The one that tman69 showed is the one that you are talking about.

Because users do exactly what you are attempting to do. If you had succeeded, you could then watch as your computer boots to a black screen (never showing the desktop), waits for a while and then restarts.

I understand the desire to harden a system by disabling services that are not in needed; but you really should learn that art using a virtual machine. :-)

You are welcome. I read my reply again and I hope that I did not come across as arrogant.

I've disabled these services in an XP virtual machine before, but never in a Windows 7 one. Thanks for reminding me to play with them :-)

You might want to read this website:

But be very careful want you do to a live system. Also note that there is not too much to be gained by disabling a service in Windows 7. There are security benefits, but not much in the way of performance gains.

Also note that the topic of changing Windows 7 services can stir up some strong emotions in this forum.
