I am having issues with the Start Menu. Normally, when you open the Windows 10 Start Menu, the user account is shown at the top and you can right click on it to Change account settings, Lock, Sign out or Switch account.
The other thing this is now missing is my recent history for programs. Normally, when you open the Start Menu there is a small arrow ">" next to the application that activates the "jump list". But that is no longer functioning either.
I have restarted the PC several times in case it was an update that need to finish installing but it seems to persist.
