Universal Windows 10 Emulator not starting up OS
<p>The Windows phone emulator running Windows 10 has been working since I've installed it and last time I used the emulator was a few days ago. Now for some reason when I load my application emulator does not load the OS.</p>

<p>here's the steps I go throuogh to run the app :</p>

<p>-Run "Mobile Emulator 10.0.10586.0 720p 5 inch 1GB (which is my usual emulator to run)"</p>

<ul>
<li>Message box saying "Configuring  Windows Phone for debugging ... "</li>
<li>Another message box appears saying "Click "Retry" to run the emulator in elevated mode. :</li>
</ul>

<blockquote>
  <p>You do not have permission to modify internal Hyper-V network adapter settings, which are required to run the emulator</p>
</blockquote>

<ul>
<li>Click retry on the message box</li>
<li>"Are you sure you want to run Windows Phone Packages?" Click Yes</li>
<li>Configuring Windows Phone for debugging box still running</li>
<li>Phone emulator runs but stuck on "OS is starting..."</li>
<li>Message box appears after leaving it running for roughly 15 mins :</li>
</ul>

<blockquote>
  <p>"The emulator is unable to connect t the device operation system :
  Couldn't set up the UDP port. Some Functionality might be disabled.
  will add this to the steps"</p>
</blockquote>

<p>I've followed the instructions from forums to go to Hyper-V Manager and delete the virtual switches and virtual machines - which doesn't work. And I also have Hyper-V enabled on windows features.
Any other solutions would be appreciated, Thanks in advance!</p>

<p>UPDATE : so I've left it running just to see if it works eventually, now another message box appears saying :</p>

<blockquote>
  <p>The emulator is unable to connect to the device operation system : Couldn't set up the UDP port. Some functionality might be disabled. </p>
</blockquote>

<p>UPDATE : So I managed to fix it .. a little. It works for the other apps I have as well as newly created universal windows projects. But this specific app doesn't . I notice that this specific one has the "Configuring Windows Phone for debugging" message pop up whereas the other ones don't.</p>
