64px-Internet_Explorer_7_LogoIt’s been fun TRYING to implement Enterprise Mode

Some of the hurdles I’ve found so far:

  • it’s a new technology which Microsoft is releasing ongoing bug fixes for.
  • if you are going to use Microsoft Edge, your Sitelist MUST be hosted on a web server.  You can’t use a UNC path (ie. file://)
  • Microsoft Edge does not support webpages using vbscript, so you need to set a compatibility mode for that.
  • F12 Developer Mode is inconsistent in how it detects/renders Enterprise mode.
  • IF you are using the Group Policy setting “Display intranet sites in Compatibility View”, then you are getting Enterprise Mode + Compatibility View.
  • Microsoft updated the XML schema so version 2 (Windows 10) is not backward compatible with Windows 7 or 8.1.
