How the new Edge will handle file:// URI ?
file: links seems to be ignored in this version of Edge (like they are in Chrome). In the previous version of Edge however (and all IE versions), clicking on a file: link opens the original document....
If IE is deleted, or at least disabled in "add and removed windows components", and the only Windows browser available to users is Edge; does this warning still apply?
I think the answer is yes. A bad guy could send you an email or direct you to a website that has a hyperlink that uses your custom URL protocol and launch whatever you're custom protocol allows to be launched on your in internal client machines. For example:
<a href="Myfile://C:/Windows/system32/notepad.exe">notepad.exe</a>
will launch Notepad.exe on the client machine using the registry setup I mentioned March 3rd. The powershell command in the registry needs to be changed to only allow .DOC files to be opened if that is all you need.
