Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
I'm assuming you do not want to factory reset the machine, removing the installed apps and reinstalling windows. So Assuming you just want to reset the password ***** can use a key such as this one http://amzn.to/2a9j9NO
All you have to do is plug it in, boot from the usb and easily reset the password.
I strive to provide great service, and greatly appreciate a 5 star rating clicked and submitted when you are satisfied.. I always answer follow up questions.Dustin S.Senior Technician and Network Switching Systems Operator / Maintainer.
