Fix Boot Failure: a proper digital signature was not found

August 10th, 2015 by Admin

I have a Toshiba P850/02c with windows 8. This morning it did an automatic Windows configure update but then on restarting, I got the error message “Boot Failure: a proper digital signature was not found. One of the files on the select boot device was rejected by the Secure Boot feature.” and stuck on there. Now I am unable to boot to the desktop. How can I fix the issues?

boot-failure

This is probably due to the “Secure Boot” feature currently on all new Windows 8/8.1/10 computers. Secure Boot is a new feature that improves the security of Windows. To fix this boot failure, you have to disable the Secure Boot option in the UEFI firmware.

How to Disable Secure Boot?

To disable the Secure Boot option, you have to access to the UEFI setup.

In UEFI setup, try to find a menu labeled “Security” or “Security Settings.” Once you navigate to it, head straight down to “Secure Boot”. There’s a possibility that you might have a “Secure Boot” option immediately when you arrive at the security menu, so look out for that also. Once you see a “Secure Boot” option, disable it. Then reboot the PC to check if that fix the issue.

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:

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

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:

Open the Command Prompt as administrator.
Type the following command to unlock your BitLocker drive with 48-digit recovery key:
manage-bde -unlock D: -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 D: -RecoveryKey "PATH_OF_YOUR_BITLOCKER_RECOVERY_KEY_FILE"

If you can remember your BitLocker user password, type the following command. After pressing Enter, you’ll be prompted to enter the user password.
manage-bde -unlock D: -Password
Next turn off BitLocker Encryption:
manage-bde -off D:
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:

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.
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.)
Double-click your desired user account in the right hand side.
In the User Properties window, click the Add button.
In the Select Groups dialog, type the name of your administrators group. Click Check Names, and then click OK.

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.

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“.
To see a list of local groups available, just type:
net localgroup
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

2 Methods to Fix “The Group Policy Client service failed the logon. Access denied.”

July 1st, 2015 by Admin

When you try to log on to your Windows account, you might encounter the error “The group Policy Client service failed the logon. Access is denied.”

When you click OK, the system will return you back to the login screen. Searching this on the net gave a lot of answers but none of them seemed to solve it. In the end we discovered that it is a permissions problem and not a corrupt profile problem. Here’s two methods to fix this issue.

Before getting started, you need to log on to your computer with a working administrator account. Then follow the solutions below to fix the problem for your affected account.

Method 1: Regain Registry Permissions

Press the Windows key + R to bring up the Run box. Type regedit and hit Enter.
When the Registry Editor opens, select HKEY_USERS in the left pane. Now, pull down the File menu and choose the Load Hive option.
When the Load Hive dialog appears, select All Files in the Files of type box. Navigate to your affected profile folder (for example, C:\Users\<user_name>) and select the NTUSER.DAT hive. Click Open.

Note: if the NTUSER.DAT file doesn’t show up, you might need to configure Windows to display the hidden files.
It will ask you for a name. Give it any name, it doesn’t matter what it is.
You will now see the hive you just loaded with the name you gave it under the HKEY_USERS key. In my example, the entire NTUSER.DAT hive has been loaded into the Registry Editor under the registry location: HKEY_USERS\NTUSER.
Right-click on HKEY_USERS\NTUSER and select Permissions.
Here you should see at least three accounts: System, Administrators and the name of your affected user account who’s profile you are fixing. If ANY of these are not shown it will not work. You need to add all three and then give them full control in the Permissions section.
Once you have added all three and given them the correct permissions, click the File menu and select Unload Hive. Close the Registry Editor.
Log off or restart your computer. You should be able to login successfully with your account that you were having trouble with.

Method 2: Deleting the Local Profile

This method works by deleting your affected local profile, so you can then log back on. After successfully logging on, Windows will automatically create a new profile for your account. Here’s how to delete the profile for your affected Windows account in Windows 10, 8, 7 and Vista:

Right-click on My Computer icon on your desktop, and then select Properties.
From there, click the Advanced System Settings link on the left-hand side.
When you see the System Properties dialog, click the Settings button in the User Profiles section.
In the User Profiles dialog box, select the profile of your affected user account and click on Delete.
Click OK to confirm. Now you’ve successfully deleted a user profile. Your problem should be fixed by now.

How to Show Hidden Files in Windows 11, 10, 8, 7 and Vista

July 1st, 2015 by Admin

One accidental deletion of a single system file can render your computer unusable. By default, Windows hides certain system files from view in Windows Explorer. This protects important files from being accidentally deleted, modified or altered.

But there are times when it’s necessary to view the hidden files and folders when coming to troubleshoot Windows problems. Here’s how to show hidden files in Windows 11, 10, 8, 7 and Vista.

How to Show Hidden Files in Windows 11, 10, 8, 7 and Vista?

Open up a Windows Explorer window, choose Organize -> Folder and search options.

In Windows 10 or 8, click on the View tab at the top of Windows Explorer, and then click Options.

In Windows 11, open File Explorer and click on the See more button (three dots) on the right side of the toolbar, and then select Options.
From the opened Folder Options box, go to View tab.
Under the Advanced settings section, click to select “Show hidden files, folders, and drives” radio button. If you are trying to get into the Windows directories, you might want to also remove the checkbox from “Hide protected operating system files (Recommended)” as well.
When you are done, just click Apply and OK, and your changes will take effect immediately.

Fix the Error “Windows cannot complete the extraction. The destination file could not be created”

June 3rd, 2015 by Admin

Windows has built-in support for zip files. It can create, extract, browse through zip files which is a nice feature but this feature can also give you troubles in some situations.

When you try to open a .zip file you’ve downloaded using Windows Explorer, you might receive the follow error:

“Windows cannot complete the extraction. The destination file could not be created.”

error-open-zip

By default, Windows will extract the files into the temp folder when you double-click on a .zip file to open it for viewing. This error means there is a problem with the permissions of the temp folder.

Here is a workaround:

Move the .zip file into one of your user profile sub-folders, like Downloads, Documents, Pictures, etc.
Right-click on the .zip file and select “Extract All”. This allows you to decompress all of the files into a folder of your choice.

Actually this problem has been faced by lots of Windows users. If you open the zip file with some third-party tools such as 7-zip or WinRAR, every file could be opened without error.

How to Fix “Your connection is not private” in Chrome

May 27th, 2015 by Admin

Whenever you try to login to Yahoo Mail, Facebook or YouTube using Google Chrome, you might get the ERR_CERT_COMMON_NAME_INVALID error:

Your connection is not private
Attackers might be trying to steal your information from site (for example, passwords, messages, or credit cards).

connection-not-private

After searching the web for solutions, most of which where pointing to system time not in sync. If your computer’s date and time is not correct, you’ll face this strange problem.

If you confirm the date is up to date, then check the anti-virus software installed on your computer which might block the website’s security certificate.

If you’re using Avast, you need to turn off HTTPS scanning in Avast: go to Settings > Active Protection > Web Shield > Customize, uncheck the “Enable HTTPS scanning” box.
For Bitdefender, open the main Bitdefender interface and go to Settings (upper right corner). From there, click on Privacy Control. Select the Antiphising tab. Switch Scan SSL to OFF.

For some situations, the problem might happen as the root certs were messed up. You have to clear all certs on your computer and rebuilt new once using Microsoft fix it tool.

Hope this helps others!

How to Change Local or Domain Password Policy from Command Prompt

May 10th, 2015 by Admin

How to disable the password complexity policy for Windows Server Core installation? If your Windows system comes with a GUI interface, you change the password policy from within the Group Policy Editor, but the steps are still a bit complicated for a Windows domain controller.

In this tutorial we’ll show you a quick yet simple way to change local / domain password policy from the Command Prompt. This method works with all versions of Windows, including Windows 10, 8, 7, Vista and Windows Server 2012 (R2) / 2008 (R2) / 2003.

How to Change Local/Domain Password Policy from Command Prompt?

If your computer is a domain controller, follow the steps below and you can change the default domain password policy. To change the local password policy on a domain controller, you must boot your server in Directory Services Restore Mode (DSRM) and then perform the steps below:

Open an elevated Command Prompt. If you’ve forgotten the local or domain administrator password and couldn’t log on, try the PCUnlocker bootdisk for bypassing the password.
Type the following command and hit Enter:
secedit.exe /export /cfg C:\secconfig.cfg

This will dump the local policy or domain policy for the system, including account policies, audit policies, and so on.
Open the C:\secconfig.cfg file with your text editor. For Windows Server Core, you can type notepad.exe in the Command Prompt. When Notepad launches, click the File -> Open menu to open C:\secconfig.cfg.
Now you can view and edit all of the relevant policies as shown below. In this example, we’ll disable the password complexity policy. So we replace PasswordComplexity = 1 to PasswordComplexity = 0, and change the value of MinimumPasswordLength to 0.
When done, save your changes. To load the edited file as your new policy configuration, use the following command:
secedit.exe /configure /db %windir%\securitynew.sdb /cfg C:\secconfig.cfg /areas SECURITYPOLICY
The new password policy will apply to all password changes and new password. After disabling the password complexity policy, you should be able to change Windows account password to whatever you like.

Using Windows Firewall to Block A Program from Accessing The Internet

May 6th, 2015 by Admin

Have you ever installed a program that you only needed for offline use, but it kept on trying to connect to the Internet? Or need to stop a program from gathering your personal information and sending them out to the Internet? With Windows Firewall you can easily block any program of your choice from connecting to the Internet.

How to Block A Program from Accessing The Internet?

To get started we need to open up Windows Firewall. One quick way to do this is from the Control Panel. Just click the Windows Firewall icon.
On Windows Firewall window, click on the Advanced settings link.
Here you can see all your Firewall rules: Inbound or Outbound. When it comes down to it I think Outbound rules are usually enough for most applications. When Outbound connections are blocked, this means that the application can’t send any of your data to the Internet.
Right-click on Outbound Rules from the tree at the left, and then select “New Rule…”
Select the Program as the rule type and click Next.
Select the “This program path:” option and then click on Browse to locate the program which you want to stop from accessing the Internet.
Select the “Block the connection” option and click Next.
When comes to the Profile tab, select all of the available boxes: Domain, Private, and Public.
Give your new rule a name whatever you like. Click on Finish.
In the Name column, your newly blocked program will be listed. In the Action column, you’ll see that your newly created rule is set to Block.

Repeat the same steps to block as many programs as you want from accessing the Internet.
