I'm seeing a lot of people having problems with this out there in computerland, so I thought I'd share what I've learned here.
I think my search index got borked, I don't even use that.
It's currently using 25% of my CPU, I hope it finishes soon, but from searching one guy said book a hotel vacation, and it will be done when you get back.
I don't use narrator, but I'm not going to emulate my own OS through EDGE.
update - Narrator is off by default.
Okay, so I killed two services,
Stopped Connected Devices Platform Service
Stopped Connected Devices Platform User Service_251eb4
and my machine stopped emulating a space heater.
That's in services.msc for people who don't know how to find them. PLEASE BE CAREFUL if you mess around in services.msc
I tried unplugging my 4 port USB hub first, thinking something got borked, but that did absolutely nothing.
As to devices connected to my computer there's the HDMI display, USB keyb, USB Mouse, USB wireless adapter, and the aforementioned 4 port USB hub.
I'd never heard of these services before today, but apparently other people have had trouble with them.
CPU usage is now sitting around 3%, top user being task manager.
USB hub is working just fine, I have NO clue why those services were such turds.
