now i installed a fresh copy of windows 7
now i can right click on any folders and the menu shows successfully but a refresh happened with it and f5 also doesn't work
when i am going to start menu pinned items and right click it shows successfully
but if i left click on all programs and right click on any items
the menu shows for 1 second and gone with the start menu like someone pressed esc button and something happened like refresh
now i think it's from registry may be from some programs that i have installed

Hi and welcome to SevenForums,
Did you revert back to win-7 from win-10 ?
If so did you restore a real system image after using win-10 revert back to win-7 to really undo win-10 ?
