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.
• Next, right-click on every Host Controller and then click on Uninstall Device.
• After uninstalling every entry, restart your computer to force your system to reinstall the drivers you’ve just uninstalled.
• Once your computer has rebooted, wait until the drivers are reinstalled and then try opening DisplayLink again.

Option 5 – Reinstall the Universal Serial Bus controller

You can also try to perform a System Restore as it can also help you fix DisplayLink. 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.

Error Code 0xC004C020 (Code 0xC004C020) – What is it?

Error code 0xC004C020 (Code 0xC004C020) is an error that occurs when you attempt to activate a copy of Windows 7 with a key, but the key has already been activated multiple times. When receiving this error code, it means that you are trying to exceed the number of times that the Windows 7 key is allowed to be activated. Common symptoms include:

• Attempting to install Windows 7 with a key and a dialog box with the code 0xC004C020 is displayed.
• The computer is unable to install Windows 7 with the key.

• You are not able to use your previously used key to install Windows 7.
• You have used the Windows 7 key the maximum number of times allowed.

Error code 0xC004C020 simply means that the Windows 7 code that you are trying to use to install Windows 7 has already been used the maximum number of times allowed, even when installing it on the same computer that it was previously used on. This would indicate that the key is what is known as a volume key- meaning that there is a cap on the number of uses.

Further Information and Manual Repair

Many people encounter this problem when they are doing software development or testing and need to reinstall Windows 7. Some people might also encounter this error code when installing Windows 7 with a key that was used too many times previously. It should be noted that there are several ways to fix this problem, but if nothing is working, you should contact a computer repair technician.

Method One

Activate by phone- the long method.

1. Click the start button, right-click Computer, click Properties, and then click Activate Windows.  This will open Windows Activation.
2. Click on “Show me other ways to activate”.
3. Find and enter the Windows 7 key, then click Next.

1. Click on Start, type: slui.exe 4 into the Search box
2. Press Enter on the keyboard.
3. Pick your country.

Method Three

Error code 0xC004C020 occurs if you have used your Windows 7 activation key on multiple computers, or multiple times on the same computer. You are not allowed to exceed the uses of the key—you should consider purchasing a new key if this is the case. A Windows 7 key is available for purchase online through the Microsoft website, in the shop section. The new product key must then be activated within 30 days, or it becomes no longer valid. It can be activated online or through the telephone. If it is not activated on time, features will stop working until the new key has been activated. This should be the last resort method, as you should not have to purchase a new Windows 7 key code if it is not necessary. 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.

Google's Pixel smartphone is one if not the best Android smartphone on the market. It regularly gets updates and Google is really trying to keep it as a top choice for Android smartphone users. One of the new things that Google has released for its smartphone series is a new emergency dialer.

With an emergency dialer, you will be able to quickly access local contact information for police, fire, and medical services. This dialer is able to contact before mentioned services even when the phone is locked and when you are traveling.

The idea is to quickly access the default emergency number no matter in which country you are currently in, service will find the appropriate number and set it as default so if you need it there is no delay in searching for the appropriate number and dialing it.

Once the service is enabled on the device you can swipe up and tap Emergency call without unlocking your phone or you can press and hold the power button for five seconds and tap Emergency.

If you have a Pixel smartphone go to the Google support page and follow instructions on how to enable this service. It costs nothing and it could potentially even save your life.
