Question about Remote Assistance - should I allow it?

I was going through some of my inbound firewall rules. Remote Assistance appears to be enabled by default on Windows 7. Not only that, there are several rules allowing it inbound access.

here they are:

DCOM-In
PNRP-In
RA Server TCP-In
SSDP TCP-In
SSDP UDP-In

I only vaguely understand what some of those designations are. I can't imagine I would EVER need remote assistance -- doesn't that just allow for remote access into your PC for "help"? Sounds like a security disaster waiting to happen. Should I kill all these inbound rules or keep them?

THANKS guys!

 

If you don't need Remote Assistance, you can just disable it by Start Panel -> Control Panel -> System and Security -> System -> Remote settings -> untick the "Allow Remote Assistance connections to this computer"-box and the firewall will adjust. If you ever need Remote Assistance, just tick this box again.
