Fix Windows Update Error 0xc1900403

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.

Ever gotten an e-mail offer that seemed just a little bit too good to be true? Might’ve been a phishing attempt! These are everywhere and can come in many different forms. 

So what’s phishing exactly, how can you detect it and how can you keep safe?

What is phishing?

Phishing (pronounced like fishing) is a type of cyberattack that tricks the user into trusting the source and revealing sensitive information. Fishing being the perfect analogy, the bait is a legitimate-looking site, e-mail or file and when you take a bite, your identity, banking information and much more can be revealed and stolen.

Some phishing attempts are incredibly obvious, others are super elaborate. Like with most types of malware, cybercriminals have become extremely well-versed in phishing and anyone can fall for it. To help you recognize and avoid it, we’ll take you through a couple of phishing types and give you tips on what to do if faced with them.

Phishing techniques

E-mail phishing

This is actually the most common type of phishing. A cybercriminal creates an e-mail containing stuff like attractive offers, legitimate-looking attachments or links and makes it appear as though it’s coming from a trusted source.

For example, it looks like it’s coming from your bank or your favorite retailer. The logo looks legit and the structure of the e-mail seems familiar, so you might get tricked into clicking on whatever clickable content is in it.

Unfortunately this exposes your device to malware that hands your data off to the hacker, who can decide what to do with it further.

SMS and social media phishing

Like the above example, you could be approached with lucrative offers or links via text messages or social media messages. Typically, the messages seem relevant to the user as they will be made to look like they’re related to apps or services you’re using.

Voice phishing

Voice phishing attacks are schemes that appear as though they’re coming from a credible number. Normally, you’ll get a call about something related to credit cards or taxes to get you into a state of worry, leading you to disclose personal information on the phone.

Spear phishing, whaling and BEC

Spear phishing normally targets specific individuals within a company who are likely to have access to sensitive data. Spear phishers spend time collecting information they can use to reach out to the individual looking as trustworthy as possible. They’ll typically lead with something relevant, for example mentioning an upcoming company event, and make a seemingly legitimate request.

Whaling is a more elaborate form of spear phishing, which targets people in even stronger positions such as executives or high-value individuals. The ultimate goal is to get them to transfer financial or other sensitive information that can be used to compromise the entire business.

BEC, or Business e-mail compromise, is a specific spear phishing technique carried out via e-mail. While there are many ways this is done, most commonly you’ll see instances where the phisher poses as a CEO or similar executive, or as a lower-level employee in specific positions (e.g. sales managers or financial controllers).

In the first situation, the impersonator reaches out to employees requesting them to transfer certain files or pay invoices. In the second situation, the phisher takes control of the employee’s e-mail account and sends false instructions to other employees in order to obtain data and information from them.

What can you do?

There are many ways you can be aware and spot a phishing attempt. Here are some tips:

• Always check the sender’s address in your e-mails, even when they seem to come from a familiar source.
• In any instance where payment information is requested, be very, very careful.
• If you are receiving attachments you never asked for and definitely didn’t expect, better not click on them. 
• Beware of content that transmits a sense of urgency (sales deals, urgent updates to login credentials, etc.).
• Bad spelling and grammar are usually a telltale sign of phishing.
• Links that look shortened (e.g. Bit.ly) or just suspicious in general - if you have a bad feeling, do not click on them.
• If you are receiving threats, you probably shouldn’t be clicking on anything in that message.
• Always examine first-time senders in detail.
• Block suspicious e-mail addresses, numbers and social media accounts.
• If you are receiving a coupon for free stuff… You aren’t.
• If you’re being asked to update your payment details by a service you use, such as Netflix, chances are it’s an impersonator.

Those are some of the ways to identify and prevent phishing attacks. However, sometimes phishers disguise themselves a little too well or a misclick happens and there you go - you’ve been exposed to malware.

This won’t happen if you invest in powerful protection software from the get-go, though. A good antivirus program like Bitdefender will keep you safe from becoming a victim of phishing scams. In fact, it will protect you from malicious attacks overall.

Be it your household or your business you’re concerned about, there are a bunch of different packages and options available, providing different kinds of cybersecurity services. That’s the only way you can ever really be sure you aren’t at risk of a digital attack.

Summary

Have you ever been targeted by phishers and didn’t know that’s what it was until you read this article? Many can relate. Protect yourself before it’s too late!

In case you don’t know, Windows 10 actually allows users to set the Keyboard Repeat Rate and Repeat Delay. Both of these terms are interrelated and when you make active, any text field or an editor and then press and hold a single character key, it will quickly type the character for the first time and will show delay until the second and later characters appear. This is what you call the Keyboard Repeat Delay. On the other hand, the rate at which the later character appears is known as Keyboard Repeat Rate. There are two ways you can set the Keyboard Repeat Rate and the Keyboard Repeat Delay on Windows 10. The first one is using the Keyboard Properties while the second one is using the Registry Editor.

Option 1 – Set up Keyboard Repeat Rate and Repeat Delay via Keyboard Properties

• First, tap the Win + R keys to open the Run dialog box and type in “control keyboard” in the field, and hit Enter to open the Keyboard Properties.
• From there, you can use the slider to make the respective options for both Keyboard Repeat Delay and Repeat Rate shorter or whatever you prefer them to be.
• You should also see a text field in the mini window where you can test out your preferences. Once done, click on the Apply and OK buttons to save the changes made.

Option 2 – Keyboard Repeat Rate and Repeat Delay via Registry Editor

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERControl PanelAccessibilityKeyboard Response
• From there, you can set your own value for both the AutoRepeatDelay and AutoRepeatRate registry keys so that you can set the Keyboard Repeat Rate and Repeat Delay in Windows 10.
• Once you’re done, exit the Registry Editor and restart your computer to save the changes made.

TPM, also known as Trusted Platform Module, is a specialized chip used for security as well as encryption of users’ private data like Fingerprint, Facial data, and many more. TPM also comes with a Management Console and if you are not able to load the Management Console and you got the “Cannot load Management Console” error instead, read on as this post will guide you in fixing the problem. This type of issue usually happens when you clear or disable the TPM using the settings in the BIOS and so when you run the Trusted Platform Module Management console, you encounter the error. To fix the “Cannot load Management Console” error in your Windows 10 computer, here are some options you should check out.

Option 1 – If TPM is cleared in the BIOS:

If the Trusted Platform Module is cleared in the settings of the BIOS, you have to close and restart the TPM Management console or TPM.msc once again. It could be that the TPM Management has to reload the changes again after you’ve made them which is why you encounter the “Cannot load management console” error.

Option 2 – If TPM is disabled in the BIOS:

If you opted to disable TPM using the BIOS settings or you have turned it off by accident, then you have to enable it back and you have two options to do that – you can either enable TPM from the BIOS or using the Windows PowerShell. For more details, refer to the instructions below.

Enabling TPM from the BIOS:

• You need to first reboot your PC and then go to the BIOS.
• From there, look for TPM under the security options and in case the TPM management option has been disabled or greyed out, refer to the sub-steps given below to make it active again
  • Enable the Admin password in the BIOS.
  • Then go back to the TPM settings and check if the TPM management is already available.
• After that, you should now be able to enable TPM. Remember that it’s always a good idea to have an ADMIN password for your BIOS as it makes sure that no one can change the settings in your computer BIOS and Security level options.

Enable TPM via Windows PowerShell:

• This second option is a lot easier compared to the first one if you have admin privileges. So once you’ve opened the Windows PowerShell with admin privileges, you need to run the following command:
  • $tpm = gwmi -n rootcimv2securitymicrosofttpm win32_tpm
  • $tpm.SetPhysicalPresenceRequest(6)
• After you execute the commands given above, you need to restart your computer.
• Now, once your computer has restarted, you need to accept any BIOS prompts and then check if the “Cannot load management console” error is now fixed.

USB ports, just like any other ports, also comes with a power rating. The default power output of a standard USB port is 0.5 amperes and if you notice, mobile phones charge slowly on USB ports which explains why. There are times when Windows may throw an error or warning that says, “Power surge on the USB port”. This kind of error occurs when a connected device tried to draw more power and the error comes as a part of that notification so when you select it, it will say,

“A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device”.

To easily fix the problem, you can try to disconnect the device and click on Reset and if you click on Close, the port will not work until you unplug it and then restart your computer. On the other hand, if disconnecting the device did not resolve the problem, you can try running the Hardware & USB troubleshooter or use a USB hub. You can also try to reinstall, uninstall or roll back the USB drivers or run the OEM diagnostics. For more information, refer to each one of the potential fixes provided below.

Option 1 – Try to run the Hardware & USB 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.

Note: You could also try to run the USB troubleshooter as it could also resolve the problem.

Option 2 – Try to use a USB hub

If you’ve encountered the error on a specific device, then it is possible that the device requires more voltage. To fix this error, you can try to use the same device on another computer and if you still got the same error, you might want to use a USB hub that comes with its power source. USB hubs come with high-speed charging ports that should be able to supply the power needed for the device.

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

If updating the drivers of the device did not fix the “The device is not ready” error, you can try to update, rollback, or reinstall the Universal Serial Bus Controller drivers instead of 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 – Try running OEM Diagnostics if you have any

If the laptop or desktop computer you are using is a branded one, OEMs usually include software to diagnose issues in the computer like the USB port error. So if you have this software, try to run it for diagnosis and use any given suggestions to fix the error.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.

The Windows Update service, just like other services in Windows 10 may sometimes experience some issues and stop behaving properly. One of the issues you might encounter as you use the Windows Update service is the Windows Update error 0x8024A10A. This kind of error code signifies that the Windows Update service is shutting down.
