I have an ASUS laptop that is on Windows 7 Home Edition. I made the mistake of yielding to the insistent messages inviting me to use Windows 10. After I realized that this version does not work with Firefox or with kapersky nor with my printer, etc, I made the operation called 'rollback' of Windows 10 to Windows 7.
I have a problem: It seems I came back under Windows 7, but the touchpad of my computer is locked and left right keys of the same pad to. My wireless mouse also no longer running, the cursor remains frozen in the middle of the screen and i could not move it. It seems that the enter key works because i can walk out of standby but ctrl + a not working for example.
What I tried to do: relaunch my system 3.4 times, press FN + F9, F6, F4, num lock. Nothing worked. Help me please.
