I was able to port my favourites / history etc into Edge using another login but with my main account email, opening in safe mode with my account I could fix the problem.
I now cannot login to my account, it allows me in but only as a temporary user which means I can only access my docs via the C drive and most of the apps associated with the account including VMware don't work and if I log out /in I have to re-enter everything including my Live Mail
I need the pc for work so presumably I have to pay MS to get a real person to resolve it?
