reset new computer password Windows 8

I'm trying to reset the password on my Sister in law's new computer with windows 8. It is a Compaq CQ58 notebook with AMD operating system. One of her kids set it up and can't tell us what the pw is. How do I do this? Any help appreciated.

Same way you do with Windows 7 & Vista, You will either need a password key disc, or a password tool on a USB or CD/DVD that will allow you to go in and remove the password. Here is one such tool & description on how to unlock http://windows8passwordrecovery.com/
