HTML Href=" myown.html" in my C: drive stopped working. It works fine for href="http:// somewhere".
By specifying myown.html by absolute path or relative path do not matter. target="_self" or "_top" do not matter.
F12 of debug or something else do not give me any information. href="NotExisting.html" do not give me any error message.
It has been working before Sep. 13th Windows update for many years. I have been using Windows 10 more than one year. It works fine by using Chrome browser.
