Windows 10 build 15046

Release date: 02/28/2017

Known issues in build

  • Pressing F12 to open the Developer Tools in Microsoft Edge while F12 is open and focused may not return focus to the tab F12 is opened against, and vice-versa.
  • Sometimes, launching F12 will launch the F12 window behind the active Microsoft Edge window.
  • Issues may occur when exploring pages in F12 with cross-origin iframes (e.g. the DOM explorer shows only the iframe DOM, the Console frame selector doesn’t list the iframes, etc.)
