Okay, so this one is kind of more complicated to solve than the other questions. Like the others, my Windows 10 taskbar is COMPLETELY unresponsive, but the thing that is different is this:
My function keys will not work.
I cannot open task manager without it crashing and not even loading up.
My Windows key will not work, so anything stating "Use the Windows Key + (insert key)" will not work for me.
I've spent 5 hours on this download and I cannot rollback to Windows 8.1 due to me being unable to use the taskbar or anything else.
