How to Bypass Windows 7 Password

Method 1 of 4:

Using a Windows System Repair Disc

Insert a system repair disc into the DVD drive. Booting from a Windows 7 system repair disc will enable you to create temporary backdoor access to reset your password.^[1]
1. If you don't have a System Repair disc, you can create one on another Windows 7 computer.
Reboot your computer. When prompted, press any key on the keyboard to finish booting.
1. If the computer boots back to the login screen instead, you'll need to change the boot order in the BIOS before continuing with this method.
Select 'Windows 7' under 'Operating System.' When selected, the text will turn blue.
Make note of the drive letter under 'Location.'
1. For example, if you see (D:) Local Disk, the drive letter you should remember is 'D:'
Click Next.
Click the 'Command Prompt' link. A black screen with white text will appear.
Type the drive letter at the command prompt.

3. Type copy cmd.exe utilman.exe and press ↵ Enter.
4. Type exit and press ↵ Enter.
Eject the system repair disc.
Reboot the computer. The computer will boot back up to the login screen.
Click the 'Ease of Access' icon. It's at the left corner of the screen and is blue with a white compass. This will open the command prompt instead of the Ease of Access center, but don't be alarmed!
Type net user username newpassword. Replace 'username' with the username of the account you need to access, and 'newpassword' with a password you'll remember.
Press ↵ Enter.
Close the command prompt.

Open the command prompt as an administrator. Here's how:

3. Right-click 'Command Prompt' in the search results and select 'Run as administrator.'
4. If prompted, confirm that you really want to run the program as an administrator.

1. Type the drive letter you made note of earlier. For example, D:.
2. Press ↵ Enter.
3. Type cd windowssystem32 and press ↵ Enter.
4. Type copy utilhold.exe utilman.exe and press ↵ Enter.

Method 2 of 4:

Using the Windows Installation DVD

Put a Windows 7 installation DVD into the DVD drive. You can access an Administrator account by booting from DVD and making a few changes in the registry.^[4]
1. It doesn't have to be the same DVD you used to install Windows, so you can borrow one if necessary.
Reboot your computer. It should boot to a screen that asks you to choose a language.

Click Repair your computer.
Select your Widows installation.
1. Click the Windows 7 installation in the list. Unless you have other operating systems installed, it should be the only option.

Type regedit and press ↵ Enter. The registry editor will appear.
Click HKEY_LOCAL_MACHINE. It's on the left side of the screen.
Click the 'File' menu.
Select 'Load Hive.'
Type %windir%system32configsam. You'll be typing this into the 'File name' field. Be sure to type it as shown.
Click Open. Now you'll see a screen asking you to enter a name for a 'new hive.'
Type temporary. You can type anything, but this is a safe bet for the meantime.
Click OK. Now you'll return to the main registry editor.
Navigate to the user registry key. Here are the steps to access 'HKEY_LOCAL_MACHINE > temporary > SAM > Domains > Account > Users > 000001F4':

Find the line that starts with 0038. You will see 11 directly to the right of 0038.
Change 11 to 10.
1. Drag the mouse across the 11 so that only that number is highlighted (no spaces on either side)
2. Type 10.
Click OK. The hard part is over!
Eject the Windows DVD.
Restart the computer.
Click the Administrator account. This will give you full administrative access to Windows.
1. Now you can reset the password for your regular admin account.

Method 3 of 4:

Using NTPassword

Access another computer. If you have access to another computer with internet access, you can download a utility called NTPassword that will help you reset your Windows 7 password. You'll need to either burn a bootable copy of this utility or use it to create a bootable USB flash drive.
Navigate to http://www.ntpasswd.com/.
Select a version of NTPassword. Click one of the following buttons to download the NTPassword files:^[5]
1. Click Download USB Version if you want to create a bootable USB flash drive. The drive you use should have nothing else on it.
2. Click Download Disc Version to save the file (cd140201.iso) image to your computer. Once downloaded, you'll be able to burn a bootable CD of this image.

3. Right-click 'Command Prompt' in the search results and select 'Run as Administrator.'
4. Type cd x: (replace 'x:' with the actual drive letter of your USB drive) and press ↵ Enter.
5. Type X:syslinux.exe -ma X: (replace both X: with the actual drive letter) and press ↵ Enter.
6. Remove the flash drive from the second computer.
Create a bootable CD. If you choose Download Disc Version:
1. Insert a recordable CD-R or DVD-R.
2. Right-click the downloaded file (cd140201.iso) and select 'Burn to disc.'
3. Follow the prompts to create the disc.
4. Eject the disc from the second computer once the burn is complete.
Insert the USB drive or CD into the problem computer.
Reboot the computer. The computer should boot to a black screen with white text that begins with 'Windows Reset Password'.^[6]
1. If the computer boots back to the login screen instead, you'll need to change the boot order in the BIOS before continuing with this method.
