How to Decrypt BitLocker-Encrypted Drive from Command Line

July 30th, 2015 by Admin

If you still have admin access to your Windows computer, you can decrypt the BitLocker-encrypted drive easily from the Control Panel:

  1. After opening up the Control Panel, click the System and Security link.
  2. click on BitLocker Drive Encryption to launch the BitLocker configuration panel.
  3. Find the drive on which you want BitLocker Drive Encryption turned off, and click Turn Off BitLocker.
  4. A message is displayed, informing you that the drive will be decrypted and that decryption may take some time. Click Decrypt the drive to continue and turn off BitLocker on the drive.

Sometimes things would get a bit tricky if your computer won’t start or you lost admin access to your Windows account. You might need to boot off your PC from a WinPE bootable disc and decrypt the hard drive through the command line utility – manage-bde. Here’s how:

  1. Open the Command Prompt as administrator.
  2. Type the following command to unlock your BitLocker drive:
    manage-bde -unlock C: -RecoveryPassword YOUR-BITLOCKER-RECOVERY-KEY-HERE

    If your BitLocker recovery key is stored in a file on an external drive, then use this command:
    manage-bde -unlock C: -RecoveryKey "PATH_OF_YOUR_BITLOCKER_RECOVERY_KEY_FILE"

  3. Next turn off BitLocker Encryption:
    manage-bde -off C:
  4. Now you have unlocked and disabled BitLocker.

Problem with Using Chntpw to Reset Password

July 29th, 2015 by Admin

I tried to reset the password of Windows 7 Using chntpw command in Ubuntu. The program appears to work exactly as expected, and doesn’t display any errors, and acts like it’s done everything properly when blanking or changing a password. However, when Windows is loaded, no change has been made – the password has not been blanked or changed.

Chntpw, also known as Offline NT Password & Registry Editor, is a free Linux tool that allows you to reset or edit Windows user passwords stored in the SAM database. Here are a list of problems you might experienced when using chntpw to reset a lost Windows password:

  • Chntpw boots for a short while and ends up in a kernel panic “Kernel panic – not syncing: Attempted to kill init! And then it stops booting.
  • Failed to blank or change password. Chntpw said successfully clear the password. But when you try to login from Windows it does not seem to be changed.
  • Unable to mount the hard drive that that contains the Windows registry hives. Get the mount issue “Windows is hibernated, refused to mount. NTFS: Yes, but hibernated.“, or crash with “VFS: Unable to mount root fs on unknown-block.
  • Chntpw: Unable to open/read a hive, exiting..
  • Chntpw hangs in a loop, or fail to boot even if your computer is configured with UEFI and Secure Boot.

What to do if chntpw doesn’t work on your computer? You can get around all these issues with the third-party Windows password bypass tool – PCUnlocker, or use the following methods:

2 Options to Add a User to Local Administrators Group

July 13th, 2015 by Admin

Only an administrator can perform the administration tasks such as installing a driver or an application. If you have an existing standard or limited account, you can grant it administrator privileges by adding it to the built-in Administrators group. Here are two options to add a user to the local Administrators group in Windows 10, 8, 7, Vista or XP.

Option 1: Computer Management

The easier way to add a user to the local Administrators group is to use the Computer Management app. Here’s how:

  1. To open the Computer Management, right-click on My Computer icon on your desktop and then select Manage. Another method is to press the Windows key + R to bring up the Run box, then type compmgmt.msc and hit Enter.
  2. When the Computer Management window opens, expand Local Users And Groups in the left pane, and click on Users (Please skip to the option 2 below if you don’t see Local Users and Groups.)

    local-users-and-groups

  3. Double-click your desired user account in the right hand side.
  4. In the User Properties window, click the Add button.

    account-properties

  5. In the Select Groups dialog, type the name of your administrators group. Click Check Names, and then click OK.

    select-groups

    If you don’t know the name of your administrator group, click Advanced and next click Find Now.

Option 2: Command Prompt

However, not every edition of Windows have the Local Users and Groups entry in the Computer Management (for example, Windows 8 Home and domain controller). This method will work on all editions of Windows.

  1. Open an elevated Command Prompt. In Windows 10 or 8, press the Windows key + X and then click “Command Prompt (Admin)“. In Windows 7 or Vista, go to Start > All Programs > Accessories, then right-click on Command Prompt shortcut and select “Run as Administrator“.
  2. To see a list of local groups available, just type:
    net localgroup
  3. You can add a user to the built-in Administrators group by running the following command:

    net localgroup Administrators [username] /add

    For example, add a user named test to the administrators group, we can run the below command.
    net localgroup Administrators test /add

    add-user-to-group

How to Bypass the Password on Any Windows Version

July 6th, 2015 by Admin

There are lots of people that for some reason forget the login password on their Windows computers. Most of the answers they find all over the Internet is to reinstall or reset the password. This is not the answer you’ll get here. Today I’ll share with you how to bypass the password on any Windows version, not just reset it.

How to Bypass the Password on Any Windows Version?

  1. Download the required password bypassing tool – PCUnlocker. Once it’s finished, double-click the zip file to extract it. You will then need to burn the ISO file to a writable CD using a program like ISO2Disc.

  2. Insert the CD into the computer that needs its password bypass and boot from it. You may have to change the computer’s boot order in the BIOS in order to boot from the CD.

  3. If you boot from the CD successfully, it will run the Windows PE environment from memory. When the PCUnlocker application opens, you’ll see a list of Windows user accounts that are discovered on your computer.
  4. Here we’re not going to reset the user password, so don’t click the “Reset Password” button. At the bottom-left side of your screen, there is an Options button. Click on Options and select “Bypass Windows Password”.

  5. Confirm your password bypass operation and click OK to proceed.

  6. When you see the Congratulations dialog box, you’re almost done!

    Restart your compute and take out the CD. When it boots to the Windows login screen, click the icon of any User account (supporting Windows 8 Microsoft account) and you can login with arbitrary password.

I have tested this procedure on Windows 10, 8.1, 8, 7, Vista, XP and it works fine, so if yours somehow does not work, go back through the steps again and make sure you have not missed any step. Or check out the boot up toubleshooting guide for PCUnlocker.

July 3rd, 2015 by Admin

“My laptop was installed with Windows 7 with only one account, but no reset disk was created. Now I had forgotten my administrator password and don’t know how to reset it.

Had tried Ophcrack to burn its ISO into a flash drive, but failed to recover my password. Is there any way to reset my password without formatting my whole system disk?”
