Forgot to note: ALT+X is the menu button in the Original Edge, that is unquestionable.
You do not have the new Edge, and I'll bet if you do ALT+X, Open the Settings item, and scroll to the bottom of the General Settings, which opens initially, you are going to find, under the About this app section exactly what follows or a version number very close to it:
Microsoft Edge 44.18362.449.0
Microsoft EdgeHTML 18.18363
That is absolutely, positively not new Edge.
