Fix Chrome ERR_BAD_SSL_CLIENT_AUTH_CERT

This post will guide you in what to do if the DisplayLink in Windows 10 is not working. There are several users who reported that their DisplayLink device has stopped working with the Windows 20 Anniversary or the Creators update all of a sudden. According to users, this issue occurs right after they finish installing a big Windows Update like the Anniversary Update or the Creators Update or right when the DisplayLink driver is updated using Windows Update. DisplayLink is a graphics transport technology that allows users to connect to any computer that supports USB or Wi-Fi. Aside from that, it is also an excellent universal docking solution to any platform which makes it a great solution for enabling multiple displays. Thus, it can be quite annoying when DisplayLink suddenly stops working. There really is no actual error message when it happens. The only telltale sign is that all the devices that use the DisplayLink technology will also stop functioning. There could be tons of reasons why DisplayLink stopped working. It could be due to an incompatible driver, or the DisplayLink driver itself is corrupted or is connected to a USB 2.0 port. In addition, the problem could also be due to the Nvidia Share (ShadowPlay) that conflicts with DisplayLink or that the Universal Serial Bus is broken. To resolve the issue, refer to the following options laid out below.

Option 1 – Run the Hardware and Devices troubleshooter

As you know, Windows comes with a built-in tool that you can use to troubleshoot the problem with DisplayLink. You can find it in Settings > Update & Security > Troubleshoot. For further instructions, follow these steps:

• 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 2 – Try to uninstall DisplayLink and reconnect the docking station

If the Hardware and Device troubleshooter is of no help, you can try uninstalling DisplayLink and reconnecting the docking station. To do so, follow these steps:

• Disconnect the docking station or any other device that uses DisplayLink.
• Tap the Win + R keys to open the Run dialog box.
• Then type “cpl” and hit Enter to open Programs and Features.
• From there, look for DisplayLink, right-click on it and click Uninstall.
• After that, follow the next on-screen instructions that appear on your screen to completely remove DisplayLink from your computer.
• Once you’ve uninstalled DisplayLink, click this link to download and install DisplayLink again.
• Now reconnect the docking station as well as other devices that use DisplayLink and follow the next on-screen instructions to reinstall the required drivers in your computer.
• Restart your computer and then check if DisplayLink is now working fine or not.

Option 3 – Try using a USB 3.0 port

If you are experiencing this issue with DisplayLink with a monitor that you’re trying to connect using DisplayLink, then you have to make sure that you are using a USB 3.0 port. Based on some reports, there are certain monitors that will not work with DisplayLink while connected to a USB 2.0 port since they have insufficient power to run the monitor. Like pointed out earlier, the problem with DisplayLink might have something to do with the Nvidia ShadowPlay. This streaming feature was often reported to crash the DisplayLink monitors which is why you might want to try disabling it for a while to check if it’s really true. Once you’ve disabled Nvidia ShadowPlay, restart your computer and check if your DisplayLink monitor now works.

Option 5 – Reinstall the Universal Serial Bus controller

You can also reinstall the Universal Serial Bus controller to fix DisplayLink since a malfunctioning USB port can sometimes cause issues with DisplayLink.

• Tap the Win + R keys to open the Run dialog box.
• Then type “msc” in the field and hit Enter to open the Device Manager.
• From there, look for the Universal Serial Bus controllers and expand its drop-down menu.

If you are using the Windows 10 Pro version, then you have access to edit the functions in the Group Policy. The Group Policy function has the option that can disable all the default services of Windows 10. Note that in this step, you will permanently disable the “Recently Opened Files” feature. So before you proceed, make sure that you really want to disable this feature permanently and not in the meantime.

• Tap the Win + R keys to open the Run dialog box and type “gpedit.msc” in the field and click OK or tap Enter to open the Group Policy Editor.
• Next, on the left side pane, click on the “User Configuration” option and then click the “Administrative Templates” option.
• After that, select the “Start Menu and Taskbar” option and select the “Don’t keep the history of recently opened documents” option in the right pane.
• Now double click on this option and check the “Enabled” option and then click on Apply and OK buttons to save the changes made.

If you suddenly encounter the PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error then it means that your computer is under a heavy load. And if you look closely, you’ll see that it has a bug check value of 0x00000050. This kind of Blue Screen error also indicates that invalid system memory has been referenced. It could be that the memory address is wrong, or that it is pointing at freed memory. The PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error occurs when the requested data is not found in the memory. As a result, the system generates a fault which normally indicates that the system is looking for data in the paging file. However, in this case, the missing data is identified as being located within an area of memory that cannot be paged out to the disk. This Stop error might be caused by a buggy system service, antivirus program, a corrupted NTFS volume, or faulty hardware. So if you’ve recently added hardware, you can try removing it and then check. If the problem still persists, refer to the suggestions given below to fix the problem.

Option 1 – Run Memory Check to test your memory

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.

Option 4 – Flush the contents of the SoftwareDistribution folder

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history.

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.
