How to reset password for computer?

I have locked myself out of my acer laptop with microsoft windows. How do I get into the security to change my password and reset it? I did check the "hint" and I believe that I am typing the correct password. Any suggestions on how to get into it.

if you are using windows XP then this could be of help. while the laptop boots press F8 (Keep it pressed). you'll the advanced boot option screen. select safe mode. press enter. on the welcome screen you'll get an Administrator user . select it. if you are asked for a password here and the copy of XP is factory installed, call up acer customer care and ask them the password to adminstrator login.

as you edit that you are stuck during startup, you'll have to go to the bios and check out the option. there are different bios versions and companies out there soit would be easier if you tell us what is yours.
Blush! I did this stupid thing too, and I had to bring it to Bestbuy to get it fixed.

Take it to a trustworthy computer repair store.
