If you aren’t able to pull up any website and instead got the ERR QUIC PROTOCOL ERROR error message in Google Chrome then read on as this post will help you resolve the problem. When you encounter such an error in Chrome, you will see the following error message:

“This site can’t be reached, The webpage at [website URL] might be temporarily down or it may have moved permanently to a new web address, ERR_QUIC_PROTOCOL_ERROR”

This kind of error message pops up when the URL is down. However, if you are certain that the site is not down and you’re still seeing this error message, then troubleshoot further using the suggestions given below.

Option 1 – Try to disable the QUIC Protocol

QUIC is an experimental transport layer network protocol that is present in Google Chrome in order to establish a connection between two endpoints over UDP. So if there is any problem on the development side, you will most likely encounter ERR_QUIC_PROTOCOL_ERROR on your Google Chrome browser when you try to open any website. Thus, you have to disable the QUIC protocol in order to resolve the error. How? Simply follow the steps below.

• Open your Google Chrome browser.
• Now type in “chrome://flags/” in the address bar and hit Enter.
• After that, look for the Experimental QUIC protocol which should be set by default.
• Then expand the drop-down menu and select Disable.
• Restart Google Chrome and see if the error is fixed or not.

Option 2 – Disable VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 3 – Disable the Proxy server

You can also try to disable the Proxy server to fix the ERR_QUIC_PROTOCOL_ERROR in Chrome. Refer to these steps to do so:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

This guide also presumes that your hardware configurations meet at least the minimum system requirements for running Minecraft.

1. Disable antivirus and firewall

   90% of the time this is the issue why Minecraft is not working, your antivirus or firewall has detected it as a false positive, and access to system internet, etc has been cut. Try disabling it and if everything is working fine add it to the antivirus or the firewall exception list.

2. Run Minecraft as admin

   Minecraft will sometimes refuse to run if it does not has administrator privileges. To make sure this is the case locate the Minecraft executable, right-click on it and choose properties. Go to the compatibility tab and check Run as Administrator box.

3. End Minecraft process

   It came to knowledge that even if Minecraft is not running it can have its processes active in the background. Press CTRL + SHIFT + ESC to open task manager Locate if Minecraft has a process running If you find the Minecraft process right-click on it and choose End Task

4. Run Minecraft in compatibility mode

   If Minecraft still refuses to start try running it in compatibility mode in the previous Windows version Locate Minecraft executable file in its install location Right-click on it and choose properties In the properties, windows go to the compatibility tab Check run this program in compatibility mode for: Select previous version of the operating system, try Windows 8 or Windows 7

5. Update graphic card driver

   The best bet is to go to your GPU manufacturer's website and download the latest version of the driver of your GPU.

6. Remove mods, plugins, texture packs

   Mods, plugins, texture packs are all great but sometimes they can cause GPU overloads and other issues to see if this is the case try running Minecraft in Vannila mode without anything installed, just pure and clean Minecraft as it was just downloaded and installed.

7. Reinstall Minecraft

   If everything else failed, reinstall Minecraft. There might be a chance that some DLL file was deleted or corrupted by mistake or that some crucial files are missing. Clean reinstallation will fix all of these issues.

One of the smoother things that Microsoft did with the Windows 10 operating system is to separate Cortana from Search. This means that Cortana is strictly now a voice assistant and many users have seen it coming since not everyone uses Cortana. In addition, it also paved the way for other virtual assistants like Alexa to get on board with Windows 10. And now in the newly released Windows 10 v1903, Windows has brought the Voice Activation under Privacy. In this post, you will be guided on how to perform the Voice Activation troubleshooting on your Windows 10 computer. To use Voice Activation in Windows 10, follow, in the Start Search, type “voice activation” and click on “Voice activation privacy settings” listed in the search results. And from there, you can choose to allow apps to use Microphone, like listen in the background as well as select which app can access it. Each time enabled voice assistants continue to listen via microphone for the voice keyword, the app will activate itself for the keyword and will react depending on what you ask it. So if you are using a voice assistant and it didn’t respond when you speak the keyword, just go to Settings > Privacy > Voice Activation and follow these steps:

Option 1: Check the App permission to use the voice activation feature.

You have to make sure that the toggle button for the Voice activation feature is turned on globally. It can be found under the “Allow apps to use voice activation” section. You also have to ensure that the microphone is available for apps that use this feature.

Option 2: Voice activation is not working under the lock screen.

If you tend to use the voice assistant even when your computer is locked, Microsoft has a specific setting that you have to turn on. You need to make sure that the toggle button for the “Allow apps to use voice activation when this device is locked” option is turned on. However, keep in mind that the voice assistants are not locked to only recognize your voice as they also answer to anyone who will use the voice keyword.

Option 3: Check the individual permissions of apps.

If the voice assistant is not working, you have to check each one of the apps’ permissions for voice keyword, and the option to work under locked condition works.

Option 4: Run the Microphone troubleshooter.

If you’ve verified that the settings are in place, then you have to run the Microphone troubleshooter by simply going to Settings > Privacy > Microphone. From there, make sure that the toggle button for the following options is turned on:

• Allow apps to access your microphone
• Enable microphone access for the voice assistant

And if it’s a desktop app, you have to enable the toggle on at the end.

It is no secret that Fortnite is one of the most played games in the world. Epic has done a great job offering it to plenty of other platforms with cross-play feature meaning that you can play with your friends no matter on what platform they are on. But how Fortnite is a piece of software which is constantly updated and maintained it is pretty normal to have some bugs or issues from time to time. One of the before-mentioned issues is a connection issue or unable to connect to game servers. In our article, we will go through common fixes and solutions in order to get you back in-game as fast as possible. Keep on reading.

Check the Epic Games Status page

Check the Epic Games Server Status page to make sure all systems are operational. If the issue you’re experiencing is related to an outage or system-wide issue, you won’t be able to connect to the Epic Games Launcher or Fortnite until it's resolved.

Use a wired connection

Wireless connections are not as stable as wired connections. This means that the signal can be unreliable and result in packet loss, connection problems, or higher latency or ping. Connect directly to your modem or router with an Ethernet cable to eliminate this possibility and have the fastest connection possible.

Disable your firewalls

Often the quickest way to fix connection problems due to firewalls is to temporarily uninstall and/or disable it.

Windows Firewall disable guide:

1. Click on Start.
2. Click on Control Panel.
3. Click on System and Security.
4. Click on Windows Firewall.
5. Click on Turn Windows Firewall on or off (You might need to provide the Administrator password at this step)
6. Under each Network location, select the Turn off Windows Firewall option

Uninstall any other firewalls

Using a third-party firewall may prevent you from being able to connect to the Epic Games Launcher, Fortnite, or another Epic Games product. We recommend removing any third party firewalls temporarily to see if this resolves your issue. If it does resolve the problem, make sure to add the following executables as exceptions to your firewall:

Epic Games Launcher

• C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64\EpicGamesLauncher.exe
• C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win32\EpicGamesLauncher.exe

Fortnite

• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_BE.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_EAC.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteLauncher.exe

Contact your firewall manufacturer for instructions on how to add these as exceptions to it as this varies between them.

Unblock your network ports

Network ports allow certain types of data to be successfully sent over a network that is used by our services. If you have any of these blocked, it may result in you being unable to connect to our games or use our services properly. To unblock your ports on your router do the following:

Windows

First, you will need to get your default gateway and internal IP address:

1. Click on Start.
2. Type cmd and press Enter.
3. Type ipconfig and press Enter.
4. Take note of your Default Gateway and IPv4.

Configuring your router to unblock the ports

1. Open your web browser.
2. Type your Default Gateway into the address bar and press Enter. (A common Default Gateway is 192.168.1.1)
3. You may be asked for a username and password. This varies for each router. Before entering anything, try just hitting OK. If that doesn't work, try the common default username and password below: Username: admin Password: password If these don't work, you can check this website for a list of usernames and passwords based on your router model.
4. Locate the Port Forwarding page in the administration tool and click on it.
5. Make sure you have Port Forwarding selected and not Port Triggering as this is completely different.
6. On this screen, you will need to enter the ports and port ranges below with the correct protocol and local IP of which you took note of above: 80 (TCP/UDP), 433 (TCP), 443 (TCP), 3478 (TCP/UDP), 3479 (TCP/UDP), 5060 (TCP/UDP), 5062 (TCP/UDP), 5222 (TCP), 6250 (TCP/UDP), and12000-65000 (TCP/UDP).

If you have any trouble doing the above on your router, make sure to check out the router manufacturer's support site for additional instructions as these will vary from router to router.

Hello and welcome everyone, today we will be talking about dreaded keyloggers, why they are dangerous, and how to know if you might have one in your system. Keylogger is a malicious application placed in your system and hidden with only one goal in mind, to get information about what are you typing and by that means for a person who infected you to get information about your credit card information or other sensitive data. They can be introduced into your systems in various ways and often can not be detected easily. Modern antivirus applications have ways of detecting them and removing but this tutorial aims to teach you how to spot them all by yourself since new keyloggers are produced daily and sometimes relying on antivirus alone is not enough. Unlike viruses and trojans, keyloggers are not heavy on system resources and you will not feel slow down on your computer if you have one which makes them harder to sport with regular work. Some of them can be even tracking you on the website and not even be physically present on your computer. Generally, we could categorize keylogger into 4 categories:

1. Web browser-based keylogger. Some websites would have CSS scripts, input web forms, or so-called man in the middle keylogger. Lucky for us even Windows defenders with the latest update can detect this type of keylogger and successfully deal with it and how keylogger itself is not present on our system we are safe.
2. General spyware keylogger. This keylogger is present in your system, usually, it infected it via email attachment, social media download, torrent download, some malicious so-called fixer application, etc. Most antivirus applications and windows defenders can detect these types as well and remove them successfully.
3. Kernel-level keylogger. This keylogger is a more dangerous type they tend to operate underneath Windows as a rootkit and can go undetected by antivirus and windows defenders.
4. Hypervisor-based keylogger. This is the most dangerous keylogger, they use virtualization techniques to hide and mask themselves as a replica of the operating system and they scan all keystrokes by the user. These are very rare keyloggers but they do exist.

If you suspect that you have a keylogger or just want to check your system for precaution reasons follow these tips and guides and luckily you will solve your issue in no time and your data will be safe.

1. Use Task Manager to find suspicious entries.

   Task manager is a great application implemented in Windows that is constantly monitoring and showing all services, applications, and processes currently running on your system and thus a great tool to monitor your system if you know how to use it. First, open task manager by pressing CTRL + SHIFT + ESC Then take a good look into it, try to find suspicious names, probably duplicate of running application, something like Windows logon application, or keylog or anything similar which seems out of ordinary. If you manage to find a suspicious running application right-click on it and close it. Also while you are in task manager jump into the startup tab and check to see are there some unusual applications starting with your Windows, if you find anything, disable it right away. This is the most simple and quickest way to get some information right away if you suspect to have some simpler keylogger in your system.

2. Use the command prompt to monitor your network.

   In order to check connections to your computer and find potential suspicious ones start the command prompt in administrator mode, press ⊞ Win + X, and choose command prompt (administrator). type in netstat -b and press ENTER. All website and application connections to your computer are now visible. ignore svchost, edge browser, windows store, etc ad check the IP of the remaining ones using the internet.

3. Use keystroke encryption.

   Install encrypting software and even if you have a keylogger, the application will encrypt each stroke and all that attacker will get is gibberish

Please remember to always download files from trusted sources, do not open unknown emails, and do not share your information publicly. Take common protection steps in order to protect yourself in the digital world.

Microsoft sent an email to users on the Dev build channel saying that the company intends to push some builds that don’t represent what consumers will receive with Windows 11 when it officially releases. In other words, these are going to be some rather buggy builds that won’t be too enjoyable to use. The company recommends users switch from the Dev to the beta channel if they aren’t prepared to deal with the instability. We’ll have to wait and see just how buggy these builds are, but if Microsoft is actually sending out a warning about them it is very likely that builds will be plagued with issues and maybe even stability problems.

Back to Windows 10

How we can expect some buggy build of Windows 11 if you prefer a stable system over new features maybe best decision would be to switch back to Windows 10 until the new OS hits official release.

Switching from dev build channel to beta channel

Another solution, if you do not want to deal with too many issues, is to switch from Dev build channel to beta where things will be more stable. Follow the guide below in order to quickly switch to the beta channel. Following instructions only apply to Windows 11 installations that are linked up to the Windows Insider program, not clean installation of OS.

1. Press ⊞ WINDOWS + I to open settings
2. Inside settings click on Windows update
3. In Windows Update click on Windows Insider Program
4. Inside click on Choose your Insider Settings
5. Click on the button next to Beta Channel to select it (you can switch back to the Dev channel here if you change your mind)

The setting will be saved automatically and from now on you will only receive beta channel updates.

As you know, Windows 10 has a complicated mechanism for Activation which helps in the verification of a genuine copy of Windows 10. However, there are times when you might encounter some errors during the activation process. One of these errors is the error code 0xc000f074. This kind of error could be due to the Key Management Service or KMS which is unreachable by the client computer or if the key used in the SLSetAuthenticationData function call is incorrect. This kind of error mostly affects surfaces on computers that are upgraded from either Windows 7 or Windows 8.1 to Windows 10. In such cases, you may encounter any of the following error messages:

“Windows is unable to reach your company’s activation service. Please connect to your corporate network. If you are connected and continue to see the error, contact your system administrator. You can also click on the error detail to find the exact error. Error code: 0xC004F074.” “Activating Windows(R), (Key hash)… Error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information.” “Error 0xC004F074, SL_E_AUTHN_MISMATCHED_KEY, The Software Licensing Service reported that the key is mismatched.”

To fix the Windows 10 Activation error 0xC004F078, you have to use the correct key for your type of Windows copy or use Command Prompt to reinstall the key or you could also try running the Activation troubleshooter.
