reseting your password, as said above, is not possible. If you have a desktop you can sometimes format the drive, you lose all your data but you don't have to buy a new hdd or pay a data recovery place, unless you have the windows disk or thumb drive, you have to buy a new windows disk or, this is what i would do but I am biased, try a linux distro. Ubuntu is good for most computers, lubuntu is good for low power computers like netbooks.
