title: ASP.NET website issues with Windows 8.1/IE 11 browser
body: <p>We have ASP.NET application, currently we are doing compatibility testing for this on Windows 8.1/IE 11. Found some issues related to UI alignment, _dopostback and imagebutton click. Previously faced the same issues with Windows 8/IE 10 as well. Those issues are addressed by adding IE browser file in app_browser folder in the project. 
  But we have not found any ie.browser latest file for IE 11 support. From some of the blogs came to know hot fixes are there to resolve this issues.Tried by installing hot fixes in hosted machine, _dopostback and UI alignment issues got resolved. Image button click still not working.</p>
