Windows 7: I need help with user account password

Hello,
I am new to this forum and I am hoping that someone here can help me with the problem I am having on one of my laptops. I bought a laptop for my daughter awhile back. I set up a user account as the administrator being me. The issue I am having is the admn password keeps expiring. So I have to reset the password. This time I can't recall the password I previously used? I need to download a antivirus program I recently purchased for the laptop but I can't because the pc is requiring me to do this from my user account(admn account). I can't remember the password for the admn account? On top of that, I thought that the admn user account would say administrator under the account icon? I may be incorrect in recalling that though. Anyhow, I really need some help in figuring out how to reset my password so I can download the antivirus software on the pc. Also, is there a way to disable the password expiring? I am so frustrated over this. I tried everything I could think of to access my user account but no luck. Please help.
Thank You,
Kathi

Hello Kathi, and welcome to Seven Forums.

You might see if one of the options in the tutorial below may be able to reset your password.

Hope this helps,

I figured out what my password is. Now I wish I could disable the expiring of my password so my daughter doesn't have to bring her computer to me to enter my password all the time.

That's great news.

The tutorial below can help show you how to disable password expiration for the account. Since you have Windows 7 Home Premium, you'll need to use OPTION TWO.
