How to find a lost password on my computer

So a while ago my mom changed my computer password and forgot it, so therefore I haven't been able to restart my computer or shut it down in over a month, because of her I cant get mcafee to work so im pretty much open to any virus, and whenever I try to...

delete my password it says I have to know my old password... And since my screen name is the administrator I have no way I finding my password... Please help I'm so frustrated!

If you never shut your computer down and its still running in the administrator account, just create a new account with administrator privileges and your own password and forget that one.

u can just click on remove password
go to control panel then users and account click on your account then remove password
