I was lazy and only posted what I could remember (UPnP Device Host & Server Services). I've used Gibbson's small and fast utilities for a very long time, but wasn't sure if Windows 7 was supported - looks as though it should be ok to run (Jim & Steve's posts). It's been a long time since I've delved deeper into the explanations on GRC.com, since I used and trusted his stuff for over a decade.
Your post will help everyone understand "more better". There are a lot of services Windows defaults to automatic that are only used in specific environments. Black Viper has a list for Vista configurations and a reg file (min, avg, and default). Again, I'm being lazy here - I haven't checked for a Windows 7 version, although, the Vista versions would certainly cut down on a lot of unnecessary service loads (even if they do just start, check if needed, and stop)
Ok, I felt guilty, so I just checked Black Vipers site and found Windows 7 information
So you can just stop and disable these two services manually as they are the same in Windows 7 and 8.
UnPnP first stops the UPNPDH service if it is running, then disables its future operation. After this is done the SSDPDS service is stopped and also disabled. This shuts down Windows XP's external Internet server to prevent exposure to any presently known or later discovered UPnP vulnerabilities.
