Hacking Windows 7/8/10 Administrator Password


  • 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 the 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 has “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.

Step 1: Boot Some Flavor of Linux Live CD

Insert CD/DVD into the drive and reboot the machine. Start your Live DVD. You may need to go into the BIOS screen and change the boot-up order to CD/DVD drive first, HDD second.

Step 2: Navigate to Sys32

Use the file browser in your Linux environment, and navigate to%windir%/system32/. You may have to right-click and mount the Windows partition/drive first or use the NTFS-3G command.

Step 3: Rename Magnify.exe

Find and rename magnify.exe (Magnifier file) to magnify.old.

Step 4: Rename cmd.exe

Find and rename cmd.exe to magnify.exe.

Step 5: Shut Down Linux & Reboot Windows

Logout, remove the DVD and reboot into Windows.

Step 6: Get CMD Prompt Modify Accounts

When Windows reboots, click on the ease of access button in the bottom left corner.

Click magnify and hit apply. Ta-da. You have a system-level command prompt. At this point is where we will only change the Admin password and not any of the 1000 other things that could be done at this point!

Tip: You can right-click on cmd.exe and click run as administrator inside of Windows for escalated privileges. To edit files, it would never be allowed at the basic admin level (caution).

As the photo above shows, type net user to get a list of accounts. To the point type: net user administrator *

Your Options (Choose One That Applies):

Change Password:

net user username new_password

When you do so, the password changes without prompting you again.

Add an account:

net user username password /add

Tip: If your username has a space, like John Doe, use quotes like “John Doe”.

Admin that:

net localgroup administrators username /add

Delete that:

net user username /delete

Remote Desktop Users Group: (just in case)

net localgroup Remote Desktop Users UserLoginName /add

Net User Syntax Reference:

net user commands

Domain i.e. Servers:

net user for the domain

Step 7: Reboot Linux & Fix magnfiy.exe

Now you should insert your Linux Live CD/DVD and rename the files back to their original names or you will have issues later.

  1. Repeat Step 1
  2. Repeat Step 2
  3. Rename magnify.exe back to cmd.exe
  4. Rename magnify.old back to magnify.exe
  5. Log out, take out CD/DVD USB, reboot into Windows
