Fixing Error code 15 or Error code 16

Many of us are taking the google search engine for granted and it is no true that it has crawled in almost every spore of our digital lives but if we wanted a little more privacy? Do we have options or we are destined to use google and send our information to this company. What if we really wanted that our searches are well safe, secure, and private? We could try other search engines like BING but since BING belongs to Microsoft we would exchange only one company for another without making any progress in the privacy battle. Enter DuckDuckGo. DuckDuckGo is a privacy-focused search engine that’s been online since 2008. Find websites, maps, videos, news, and more without tracking your searches and serving you targetted ads. It took DUckDuckGo as you can tell sometimes to gain ground and to be recognized but finally, it got the attention it deserves. Its big breakthrough happened in September of 2014 when Apple offered it as a default search engine in Safari and since it has gained more and more ground. It seems people care about their privacy after all. Since then DuckDuckGo has been gaining ground and all the major browsers have integrated it as an option for a default search engine. In this article, we will show you how to switch to DuckDuckGo and set it as your preferred search engine in all major browsers.

1. Google Chrome

   Launch Chrome and click on the three dots in the upper right. Choose settings. Choose Search engine in the list on the left of the screen. Click on the drop-down box next to Search engine used in the address bar and choose DuckDuckGo.

2. Mozilla Firefox

   Launch Firefox, click on the three lines hamburger menu icon in the top-right corner of the window. Click on Preferences. Click on Search in the menu to the left of the screen. Under Default Search Engine, click the drop-down box and choose DuckDuckGo.

3. Microsoft Edge

   Click on the three dots menu button in the top-right corner of the window Then select Settings. Click on Privacy, Search and Services in the menu that appears on the left Scroll down to the Services menu and choose Address bar and search. Click the dropdown menu next to Search engine used in the address bar and choose DuckDuckGo.

4. Apple Safari

   Click Safari in the menu bar at the top of the screen Then click Preferences. You can also use the Command+, shortcut to quickly bring up Safari’s Preferences. Click on the Search tab, then choose DuckDuckGo under the Search engine drop-down box.

5. Opera

   Click on the Settings cog button in the sidebar on the left of the screen. Under Basic settings scroll down until you see Search engine and a drop-down box. Select DuckDuckGo from the list.

As you know, the Win + X menu, which is the shortcut context menu, is a useful way to launch several utilizes in Windows such as Power Options, Windows PowerShell, Event Viewer, Device Manager, and so on. However, there are times when you might experience difficulty in identifying the required utility. This is actually a part of the Windows 10 shell that goes out of scope in the customization of Windows 10. However, there is an easy trick you can use to do that. So in this post, you will be guided on how you can rename the options in the Win + X menu in Windows 10. In case you don’t know, the context menu is divided into three groups. Microsoft has categorized the bottom-most part as Group 1, while the middle part is categorized as Group 2 and the first part as Group 3. To rename these options, you need to use File Explorer and follow the instructions laid out below. Step 1: First, tap the Win + E keys to open File Explorer. Step 2: Next, navigate to this path: %LocalAppdata%MicrosoftWindowsWinX Step 3: From there, you should see three folders as Group 1, Group 2, and Group 3. Open the appropriate folder of your choice. Step 4: After that, right-click on the shortcut option you want to rename and then select Properties. Step 5: Next, navigate to the Shortcut tab under the Properties window. Step 6: Now in the text field of Comment, enter the new name of the option you selected. Step 7: Click on the Apply and OK buttons to save the changes made. Note: You can now either Sign back in or sign out of your Windows 10 User Account to see the result of the changes you’ve made. You could also restart the process of File Explorer via Task Manager. This will close the File Explorer as well as the shell components and then only launch the shell components again. In addition, you can check the Win + X menu to see the customized name that you’ve just set for a particular option. As you can see, even though it does not add anything extra, it is still a lot better in knowing how you can customize it.

Error code 0x8007007b - What is it?

Error code 0x8007007b will present itself when Windows users are trying to activate Windows. You may try to activate it through the update and security option, but it is likely that you will receive the same error code. Error code 0x8007007b may be presented when Windows 7 and Windows 8.1 users try to upgrade and activate Windows 10 on their computer.

Common symptoms include:

• An error message will display that says Windows cannot be activated. The KMS host cannot be located in the DNS, please have the system administrator verify that the KMS is published correctly in DNS.
• Error 0x8007007b will be displayed, stating that the file or directory name or the volume label syntax is not correct.

Solution

Error Causes

There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

• Click Start, type in regedit, and then press Enter.
• Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
• The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

There are times when we delete a system files without meaning to on your Windows 10 computer. This happens a lot for users sometimes mistake a system file for a malware-laden file or junk file when it’s actually a system file from the System32 or SysWOW64 folder. In such cases, it could affect your computer. For instance, you might not be able to reboot your PC or open Settings. If you have removed system files from any of these folders by accident and you desperately want to restore them, read on, as this post will guide you in resolving the problem. Restoring them isn’t actually hard, just make sure that you have system admin access. The good thing is that there exists Windows Resource Protection which protects registry keys and folders and even critical system files. So if there are any detected changes to a protected system file, the modified file is restored from a cached copy located in the Windows folder. However, if the Windows Resource Protection program fails to restore these files, you need to check out the given fixes below.

Option 1 – Run System File Checker scan

To restore the system files you deleted, you can try running System File Checker or SFC scan. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Boot your PC into Safe Mode.
• Hit the Win + R keys to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few while before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your computer.

Option 2 – Try to run the DISM tool

Aside from System File Checker, you can also run the DISM or Deployment Imaging and Servicing Management Tool as it could help in restoring the system files on your Windows 10 computer. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help you resolve the problem.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 3 – Try performing a System Restore

Running System Restore can also help you bring back the system files. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.

Option 4 – Try to run Automatic or Startup Repair

Startup Repair, previously known as Automatic Repair, is an advanced tool in Windows that can help you diagnose various system issues, including this one. This tool will scan system files, configuration settings, registry settings, and so on in order to fix the problem on its own. To run Startup Repair, all you have to do is boot into the Advanced Startup Options and then go to Troubleshoot > Advanced option > Startup Repair and then run it. This will resolve the problem if you have deleted any system file that’s essential to your Windows 10 PC.

Option 5 – Reset your computer

• Tap the Win key or click on the Start button located in the Taskbar.
• Then click on the Power button at the bottom right portion of the screen.
• Next, press and hold the Shift key on your keyboard and then click on Restart. This will restart your Pc into the Advanced Startup options.

Note: Once you have access to the Advanced Startup options, you have to go to the setting which allows you to Reset your Windows 10 PC. All you have to do is select Troubleshoot > Reset this PC to reach the following screen Afterward, select either the “Keep my files” option and then proceed to the next on-screen instructions that follow to reset your Windows 10 computer without losing your files.

Each you connect time external devices like scanners, printers, and the likes to a Windows 10 computer, the device either pushes the drivers through the USB or any other port, or you are expected to install the drivers through external media. In both cases, the driver will be loaded into the system, allowing you to use the device. However, it doesn’t always go smoothly as you could encounter some errors like the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory ( Code 38 )”. If you encounter such an error in the Device Manager, then this means that a previous version of the device driver is still in memory and that each time the device is used, that previous version is loaded into memory and then unloaded which triggers the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory (Code 38)” error. This kind of error occurs if the operating system loads the unwanted driver or if it fails to unload the driver. It could be that there is an obsolete version of the driver that’s still installed in the system or it could also be that you need to update your USB drivers as they could be outdated or the problem could also be due to some third party program that is interfering with the installation. Whatever the cause is, here are some suggestions you can check out to resolve the problem.

Option 1 – Uninstall previously installed drivers and reinstall their latest working version from the manufacturer’s website

The first thing you can do is to uninstall the drivers that are currently installed on your computer and then reinstall their latest working versions from their official sites. This kind of error is commonly encountered while loading drivers for scanners and printers. This is due to the fact that their drivers and software come along with a package which is usually in external media like CD or DVD. So when you install the software package, there’s a possibility that a newer version has been launched by its manufacturer. When that happens, you have to uninstall the previously installed driver package and then download the drivers from the manufacturer’s website and install them.

Option 2 – Run the Hardware and Devices Troubleshooter

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 4 – Restart your computer in a Clean Boot State

If the first three given options didn’t work and you still see the error when you connect external devices, you can try putting your computer in a Clean Boot State and then try connecting them again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect the external devices and check if the error is now gone.

In case you don’t know, Windows 10 now allows users to check the Bluetooth battery level of devices. More often than not, the accessories or peripherals users use for their Windows 10 devices are connected to it using Bluetooth technology. This high-speed low-powered wireless technology is designed to link mobile devices, computers, and other network devices over a short distance wirelessly. Monitoring the battery level of a device where Bluetooth is enabled isn’t an easy task as most of these devices do not support the Bluetooth battery monitor or the battery level display. And even when on devices that do, you still have to install additional software to find it. However, Windows 10 eliminates this requirement and all you have to do is add a Bluetooth device and connect that Bluetooth device. How? Follow the instructions provided below. Step 1: Adding a Bluetooth Device The easiest way to get your Bluetooth device battery to be displayed on your Windows 10 screen is to simply add a Bluetooth device. To do so, follow these sub-steps:

• First, turn on the Bluetooth mode on your device.
• Next, go to Windows Settings > Devices > Bluetooth & other devices.
• From there, click on the “+” button next to the ‘Add Bluetooth or other devices” option and select the type of device you want to add.

Step 2: Connecting the Bluetooth Device Once you’ve added the device, it will be visible under the “Add a device” screen.

• Now select the newly added Bluetooth device and click the “Done” button.
• After that, it will now be connected. Go back to the “Bluetooth & other devices” window and scroll down to the section of “Mouse, Keyboard, and Pen”.
• From there, move the cursor alongside the connected device to display its battery level.

Keep in mind that there are several ways in which you can display the battery information of the Bluetooth device. However, Windows 10 understands only one of them per se. So if your device is not a Bluetooth Low Energy device, Windows 10 won’t be able to show its battery information and won’t display its battery level.

NDIS or Network Driver Interface Specification is a programming interface for the network interface cards that aids in the proper functioning of a system driver in a computer network. The NDIS helps the computer system in order to communicate with other connected devices and hardware components on a computer network. In relation, the ndis.sys file is a critical system file developed by Microsoft for the Windows operating system. As you know, sys files or system files are important parts of the Windows operating system as well as a repository of system driver settings used by Windows to communicate with the connected hardware and devices. The ndis.sys files are stored mostly in a driver folder at C:/Windows/System32/drivers and as mentioned, these files are essential for the system to function properly. Although the presence of ndis.sys system file is not yet known to affect the normal functioning of the Windows OS, some of the Windows 10 users reported that they encountered ndis.sys blue screen errors on their PCs. Blue Screen of Death errors or Stop errors usually occurs when you open a program or a function. Moreover, it could also occur when the driver gets loaded during the system startup or during system shutdown. It isn’t yet clear what really causes the ndis.sys blue screen error. However, like other Stop errors, it may occur due to corrupted files, misconfigured device drivers, bad drivers, corrupted Windows Registry, missing or damaged system files, and malicious programs. Aside from the aforementioned reasons, the ndis.sys blue screen error might also occur if your hard disk is damaged and if the RAM is corrupted. In such cases, a lot of users usually disable the ndis.sys file. However, it won’t really resolve the issue since the file is required for the normal functioning of the operating system and even when you disable the file, it’s pretty useless as the file will start all over again. In addition, you might want to disable security programs or firewalls and antivirus programs in the meantime to check if these programs are the ones that are causing the error. And if you’ve determined that none of the security programs or firewalls and antivirus programs are to blame, refer to the options below that might help you resolve the DRIVER_IRQL_NOT_LESS_OR_EQUAL or ndis.sys Blue Screen of Death error.

Option 1 – Try to update or reinstall the PC device driver

The Ndis.sys Blue screen error can occur when the device driver in your computer is outdated or corrupted. Thus, you either have to update or reinstall it to fix the issue.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Option 2 – Rollback your Network drivers

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
• Then select each one of them and double-click to open a new mini window.
• After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
• Now restart your computer to successfully apply the changes made.

Option 3 – Try running the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the ndis.sys Blue Screen of Death error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Try running the CHKDSK utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
• The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Restart your PC.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the ndis.sys Blue Screen of Death error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
