title: How can I switch my signed in user in Visual Studio 2015?
body: <p>I'm using Visual Studio 2015 Ultimate (the developer preview edition), under Windows 10. I've already signed in with my own Microsoft account, and when I try to sign in with a 2nd Visual Studio account, I get an error that says I need to perform a switch operation to be able to sign in.</p>
  
  <p>I've tried the following:</p>
  
  <ul>
  <li>close down Visual Studio</li>
  <li>use the 'search the web and Windows' search box to search for 'Developer Command Prompt for VS2014' ( this is the correct Command Prompt version, at least for the VS2015 preview version anyway).</li>
  <li>right-click this, select 'run as administrator'</li>
  <li>in the command prompt go to to 'c:\program files (x86)\microsoft visual studio 14.0, and try the following commands: </li>
  </ul>
  
  <p><code>devenv /ResetSettings</code>
  (retains Visual Studio configuration)</p>
  
  <p><code>devenv /resetuserdata</code>
  (removes Visual Studio configuration)</p>
