Each time I get an automatic update, I am unable to open Edge. It just flashes on for a very short split second, then nothing. After each update, I have had to reset the computer to an earlier 'Restore Point' and this normally gets it working again, but this takes time, and I have of course lost any valuable updates. Have just run it after last nights update but it has not restored. Will have to run again with a different restore point. Suggestions please.
