few days ago I upgraded my notebook to window 8.1
but it sucks a lot, and I reverse it back to 8.0
by doing so, all programs I used to have are erased
and I can't type chinese now
I go to control pannel and confirm I do have a chinese type program
but no matter how many times I click on "shift"
I can't change it to chinese type. SOMEONE HELP ME PLEASE
