I got a windows vista computer in a clean out and would like to use it to replace my current computer. I want to reformat it, and i believe 99% of the newer computers have a partition for reformatting instead of disks. Can I access this without a password, or does anyone use a free password bypass program? I dont want to use a free program without recommendation, and don't really want to buy a program I will most likely use once.

Just to be clear, I do not intend on accessing personal info on the drive and plan to wipe it as soon as I can.
