How To Reset Your Windows 7, Vista, or XP Account Password Using A USB Flash Drive

Hack into your own computer, Reset your Windows 7, Vista, or XP account password with a USB DriveDear MrGroove, is there anyway to break into a Windows 7 Netbook if I’ve forgot my password?  I changed my password on Friday and by Monday I have no idea what I changed it to.  FYI – I’m using a Netbook so I don’t have a CD-Rom so I don’t even know if it’s possible to even rebuild my system or not?  Please help!


Broken Netbook Captive!


Hello Netbook Captive!  Lucky for you I have just the fix for your particular issue!  Fortunately you can use a groovy little open-source app in conjunction with a USB Flash Drive to crack into any Windows XP, Vista, or Windows 7 computer when you lose or forget your password.  Just follow the steps below and you should be up and running in no time!


The Fine Print:

  • The process I’m about to review will completely clear the password on the username/machine you use it on.  You will not be able to recover the password if you do not remember what it is.  The process will create a new password like you normally would after booting back up and as a result, if you’ve encrypted anything on the system using the Windows EFS encryption, you will lose access to this data… Sorry..
  • This fix requires access to the BIOS.  It also may not work on older computers that do not allow the bios to boot from USB.
  • You’ll need access to a computer with the internet and cmd prompt in order to set up the USB Drive properly.
  • Please use this information responsibly, using it to access a computer that does not belong to you is probably illegal and not groovy!

How To Reset A Lost Or Forgotten Windows Password

Step 1 – Download & Extract

Download Offline NT Password & Registry EditorOnce the download completes Right-Click the .zip file and Select Extract All.  This will decompress the contents, which there should just be a single .iso file inside.

Step 2 – Mount or Extract the .ISO

Download and Install a virtual drive software like Virtual Clone Drive or to mount the extracted cd100627.iso.

(Click here for instructions on mounting .iso files to a virtual drive in Windows 7, Vista, or XP)

Alternatively if you have a file compression manager installed that can Extract .iso files you can also just do that.

mount or extract the cd100627 iso file

Step 3

Browse the virtual drive and copy the contents to your USB drive.

Step 4 – Identity Your Thumb Drive & Launch CMD

Click the Start Menu and Select Computer, now note which drive letter is assigned to your USB Stick.

Next, go back to the Start Menu, Type cmd in the search box and Press Enter.

Step 5 – Make the USB Drive bootable

We need to make your computer recognize the USB drive during bootup.  To do this you’ll need to enter a few lines in the cmd window that you just opened.

First switch to your USB Drive’s directory as noted in Step 4.  Just change the letter in both lines to match your letter.


Then type in the next command, again change the letter to match your drive:

syslinux.exe –ma h:

run cmd commands to make computer boot from usb

Half Done!  Plug In Your USB To The Computer In Need

Now we’re done setting up the USB stick and we have all that we need to reset the password on the Windows computer in question.  Go ahead and plug in your now ready USB Drive to the computer that you need to reset the password on.

The rest of this How To will be done on the password locked computer.

Step 6 – Setup Bios Boot device order

Restart the computer and hold down F2 or whatever the setup key is shown as during the initial boot screen.  This should bring up the bios.  In the bios look for Boot order, or Boot Device Priority, it will vary what it is called depending on the manufacturer.

If you have trouble navigating the bios, controls are usually shown at the bottom of the screen.  It’s keyboard only, you can’t use your mouse here.

bios device priority

Under boot priority set our USB Flash Drive to #1, or the highest available slot on the list.  Once you’ve got it, save changes and reboot.

Step 7 – Boot from the USB

If you set up the bios correctly your computer should automatically boot from the USB flash drive.  When it loads to the screen shown below, just Press Enter to launch the application.

press enter to boot into password management tool

Step 8 – Select Your Windows Hard Drive Partition

The program will scan your hard drive for partitions that may have Windows installed.  In the example below it found 4 different possibilities.  Type in the corresponding number for the partition that contains your Windows installation, and then Press Enter.*

*Don’t worry, if you get it wrong you won’t ruin anything, you can come back to this screen by using the quit options that appear and try a different partition.

select partition windows installed on

Step 9 – Did you guess the right partition?

If you guessed the correct partition, the next few lines will read:

DEBUG path:  Windows found as Windows

DEBUG path:  system32 found as system32

DEBUG path:  config found as config

DEBUG path:  found correct case to be: Windows/System/32/config

Does it look right?  Yes?  Good job, Press Enter and lets finish up.

If it looks wrong, Press Enter but on the next screen Type in q to go back and select a different partition.check for proper debug path

Step 10 – Select Password reset [sam system security]

Type in 1 and Press Enter.

Select which part of registry to load, use predefine choices or list the files with space as delimiter

Step 11 – Edit user data and passwords

Type in 1 and Press Enter.

Loaded Hives <SAM <System> <Security>

Step 12 – Select a Username to reset the password for

On this part, you’ll see an RID and the corresponding Username.  Depending on what is easier, you can Type in either.  If you choose to type in the RID number, you must add a 0x before the number.  For example I entered 0x03e8 for the RID 03e8. In this case, typing in the Username Lep would have worked for me too.

Select ! , quit . - list users, 0x<RID> - User with RID (hex) or simply enter the username to change: [Administrator]

Step 13 – Clear <blank> user password

Type in 1 and Press Enter.

User edit menu

Step 14 – Password cleared!

You should see a short line appear that says Password cleared!  Now we can save and quit, Type in ! and Press EnterYes, literally type an exclamation point.

type ! to quit

Step 15 – Quit and Save

Type in Q and Press Enter.

q - quit (you will be asked if there is something to save)

Step 16 – Save changes, write files back.

Type in Y and Press Enter.

about to write files back! do it?

Step 17 – Decline a new run, if it worked

If you saw a line that said ***** EDIT COMPLETE *****, then it worked.  Type in N and Press Enter.

If by chance it didn’t save successfully, Type in Y and try again.

You can try again if it somehow failed, or you selected wrong.

Step 18 – Unplug the the USB Drive and Reboot

Now you should be able to reboot, just be sure to Unplug the USB Flash Drive first!  Press Ctrl + Alt + Del to restart the computer.  If you want, you can go back in and change the bios settings, but they won’t prevent windows from loading as long as the USB is unplugged.

end of scripts.. returning to shell.. windows unlocked

Done!  <phew>

Now the computer should boot right up!  The account that you were trying to log into should now have a blank password, and depending on the systems startup settings it might just load straight into Windows without requiring a login.  Groovy eh?

    I found an easy way for Windows password reset. A Windows Password Reset Disk could do all the job for you, it can reset your lost or forgotten Windows password safely and quickly without login, you can create a Windows password reset disk with the tool “Windows Password Breaker”, then use it to reset your password.

      Obvious spammer is obvious, if you don’t have a cd-rom drive that won’t work at all.

    Dude all my debugs are not found so it won’t work what do I do?

      You may have the same problem as me before I found this article. I wrongly chose partition 1 as having the Windows installation, thinking: naturally, it’d be the same as the boot partition.. No, as mentioned in step 8 and its diagram, the correct partition’s probably 2 or 3. Mine was 2, and it was smooth-sailing after I chose that.

    I’m trying to reset an Asus EEE netbook and I’ve got as far as the Bios Boot Device Priority and have ‘removable device’ at the top which is in parenthesis and the associated message says that its disabled and I cant change the option to enable it. Can you help please?

    • Austin Krause February 5, 2013 at 4:49 am #

      Hi Clare. What model Asus EEE Netbook do you have?

      In most Asus EEE’s I’ve worked with, I noticed that there is a separate boot menu that overrides whatever the bios says. This can be found by holding down/spamming the ESC button while the computer is booting up. From within this separate boot menu you should be able to set USB to first priority.

    Thanks for your help, I have a problem where it comes up “DEBUG path: config not found” although it finds my Windows and System folders no problem. I’ve tried all partitions and I definitely have the right one – any ideas?

    I couldn’t get my USB drive with Offline NT Password & Registry Editor to boot on my UEFI laptop. Afterwards I had also tried many other freeware and paid tools. Only the PCUnlocker Live CD worked and it successfully removed my lost win8 password.

    Hi all,

    I followed the instructions and it ended up disabling the account that i was trying to open as i could not remember the password. It also did not ask me to setup a password in the above instructions, so i am assuming that the password section is left blank.

    Now i am trying with the user name “Administrator” and no password it says that the account has been disabled. i dont know where i went wrong. Please help me.
