Maybe you forgot or lost the password to your Windows Admin account, this guide will help with that. If you are trying to hack the computer lab at school then you will need a different method
Difficulty Level: 2/10
Prerequisites:
- Any Linux Live CD/DVD/USB with Live option (ex. Ubuntu Live, Linux Live, Kali, etc.).
- Ability to use said Linux CD/DVD/USB.
- Basic understanding of Windows file structure. i.e. can navigate.
- The desire to modify user account(s) on said Windows boxen.
- Physical access to said Windows box.
- Ability to use BIOS if needed.
- Ability to use command line and basic understanding of net user commands.
Things to Note:
- If you are trying to hack a coworker / boss / job / school / customer / friend / spouse's account, you are screwed because they won't be able to use the old password anymore—try explaining that.
- This hack works on Windows 7, 8, 10 and basically any that have "Ease of Access".
- Servers require "net user Administrator blabla /domain".
- This will destroy all data encrypted with EFS on the account if it's enabled (you have to enable it first).
- If you do not undo the hack after you change the password, you will get the magnifier every time you use cmd or nothing at all.
- If you modify or delete any other files in Sys32, your next boot up is doomed (maybe).
- Scared? You should be. Now let's get hacking.
