Don't think this applies either. Actually I don't think I even have pnp on.

Don't think it's this. My bios is set to do hardware pnp vs software.

Let me see if there's any other guesses to who I think this thing is trying to
contact before I suggest who I think it's contacting.
 
Try this....

Start | Run | Type: cmd | OK |
Type: netstat -an | Hit Enter |
Under Local Address do you see anything with :1900??
If yes...

Are you on a network?
If not...
Start | Run | Type: services.msc | OK |
Scroll down to and double click: SSDP Discovery Service |
Startup type: Set to Disabled | Apply | OK
Scroll down to and double click: Universal Plug and Play Device Host |
Startup type: Set to Disabled | Apply | OK

Reboot.

Start | Run | Type: cmd | OK |
Type: netstat -an | Hit Enter |

Here's what I have
UDP 4.238.24.229:1900 *:*
UDP 127.0.0.1:1900 *:*
the top is my ISP. The bottom is my email spam [popfile] setting minus the
1900. popfile doesn't use the specific defined port. It uses smtp and pop.
the bottom one for the machine is a surprise to me.

here's a quick hint you might put away for future reference. You don't always
have to scroll with well written programs. ie: the above as example, just hit
the letter 'S' and it'll bypass A-R and jump right to the S entries. then
scroll for about 4 entries to ssdp.

The same refs to 1900 appeared after a reboot. What I assume the need to
connect to the Internet over 1900 with svchost is for windows updates.
