Fixing the Nexus 4 Windows 7 MTP USB Device Failed Error

Sorry. This will be extra geeky. But a tricky digital devil had Ol Jon pulling at his graying hairs for hours. And the world must learn the solution that took Ye Old Geek hours to unravel!

The problem was that my Windows 7 system would not load the drivers necessary to connect my Nexus 4 to my PC via USB. (So that I could pull off my pictures and videos.) Removing the existing driver did not work. Installing developer tools did not work. A dozen other tricks and reboots did not work. 

What worked? A simple little shell command: 
     net localgroup Administrators local service /add

It apparently has something to do with the phone and USB and driver software all going too quickly and not negotiating properly. So Humpty Dumpty has a great fall and it takes an obscure command line to put Humpty Dumpty back together again.

Four hundred bucks worth of ultra modern  phone hardware tweaked with six words. And I don't really know why. Here comes the singularity.
