I have been running Windows 10 Pro (latest version) on my Dell Vostro 3500 laptop for several months with no major problems.
After changing my login to bypass a PIN or Password, I now find that I cannot go further than the welcome screen (see attached) which only reflects 4 icons.
I have tried shift & restart, powering up 3 times, pressing F8 at start up but I am not able to get into a boot mode. Whatever happens I just end up with the welcome screen and nowhere to go.
