oh my go my computer is messed up now - for no reason at all I have lost icons from the taskbar, there is no longer a clock. I cannot access anything from the Windows icon in the lower right. It barely works at all. Have to shut down with power button can't access shut down any more. Please somebody help! Wish I had never upgraded to Windows 10! Only worked for a few days!
p.s. I managed to see the control panel and saw an option to go back to Windows 7 - but I never had Windows 7!
