After updating Windows 10 to build 10061 windows phone emulators (all 8.1 and 10) stopped starting. I get the following error: \"Windows Phone Emulator is unable to connect
I know it's an old thread but just thought I would chime in.
What fixed it for me was going into "Turn windows features on or off"... unselecting all the hyper v boxes... restarting my computer... then selecting all the hyper v boxes again in "turn windows features on or off" and restarting again....
This fixed it for me. I tried the solutions mentioned above but they did not work.
