Hello and thank you for your question, I look forward to assisting you today. Do you have any desktop or start menu control?
So I take it your computer is locked up and does nothing at all then?
What brand of computer, and is it a desktop or laptop?
Okay,give me a minute please.
What you will need to do is restore your computer back to Windows 8. Do you know how to access the restore manager to start the process?
Still with me?
I'm sorry, I am not setup for phone calls at this time.
Good! I'm glad I was able to help.
