You can use a program called Directory Monitor to pinpoint exactly where changes are being made on your computer. I use whenever I need to locate a save file for any game. You just start it up, make a save in the game, and it will show you where the file was created or modified. Source: almost 3 years ago

Presuming you want to sell it with windows running, first make a Window boot disk so you can recover. Then use DBAN (https://dban.org/) to completely wipe the drive. Then reinstall Windows up to the setup stage. The new owner will experience it as a new computer. Source: 11 months ago

An alternative to Parted is DBAN Darik's Boot and Nuke We use this for most full Drive wipes Https://dban.org/. Source: 12 months ago

I do love all the creative ways to completely destroy a drive, but in general you should just be able to use DBAN if you just want to wipe the drive to make data recovery near impossible, but still be able to use it afterwards. Source: 12 months ago

You have a few options. The easiest in my opinion is just to smash the hard drives (assuming you don't want to reuse or sell them). Otherwise I use DBAN for permanently wiping HDDs: https://dban.org/ Try using your motherboard's UEFI BIOS for SSD or maybe even the manufacturer's utility if you have one. Source: about 1 year ago
