I know that IE 11 did not work with Microsoft RemoteApp server but IE 11 would read the X-UA-Compatible IE=9 and then render correctly.
EDGE seems to ignore the X-UA-Compatible IE=9 and does not work at all with Microsoft RemoteApp.
Since Windows 10 is using EDGE as the default, we are having to go into the control panel and changing the default browser to IE.
Any fix besides changing the default browser to IE in the control panel?
