Error Code 80240020 – What is it?

Users who receive Error Code 80240020 when attempting to install and/or upgrade to Microsoft Windows 10, are receiving the error because the Windows 10 installation folder is either corrupted or unfinished. As a result of this error code, your download and the subsequent update will not process correctly. Users who receive this code do not have to do anything specific, as it might mean that they are attempting to update before their system is ready. These users can simply wait for their computer to prompt them for the update, and then follow the on-screen instructions for the update. However, if a user is seriously wanting to update to Microsoft Windows 10 prior to the prompt, there are ways around error code 80240020. Common symptoms include:

• A dialog box appears with the Error Code 80240020
• Microsoft Windows 10 upgrade is unsuccessful or freezes in the process of updating and displays the error code message.

Solution

Error Causes

This error is only caused by one type of issue, and that is unfinished or corrupted files being present in the Windows 10 installation folder.

• Files that are unfinished in the Windows 10 installation folder are a result of the download not processing correctly, therefore the update is not successful because your computer does not have the files that it needs.
• Files that are corrupted in the Windows 10 installation folder are a result of either a faulty download or preexisting corrupted files that need to be purged.

Until your system is ready to download the new Microsoft Windows 10 upgrade, you will be unable to install the upgrade. As stated, you have the option of waiting for your system to prompt you to download (which means that your system has made the necessary changes to its own files and is ready for the upgrade), or you can use the following steps to correct the issue yourself.

Computer viruses are malicious applications that have the ability to self replicate and spread over the system and various devices, just like viruses in organisms. We all know that computer viruses are bad and that you should avoid them however you can. So in this spirit, we are taking a deeper dive into what kind of viruses exist and how they function.

1. File-infecting Virus

A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.

2. Macro Virus

This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.

3. Browser Hijacker

This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.

4. Web Scripting Virus

A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.

5. Boot Sector Virus

These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.

6. Polymorphic Virus

This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.

7. Resident Virus

A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.

8. Multipartite Virus

A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.

We’ve already covered disabling Security Questions If you want to disable Security Questions on your Windows 10 computer then you’ve come to the right place as this post will guide you in doing exactly that. In this post, you will be disabling Security Questions using a PowerShell script. This PowerShell script is called “Update-AllUsersQA”. It is designed to remove or disable the security questions and answers for local users on a Windows 10 computer. It lets administrators take control of the security questions in the environment and at the same time minimizes the risk that comes with them. If a user has a Microsoft account that’s configured to sign in to Windows 10 then he will not probably notice the Password Recovery questions. On the other hand, if he has a chosen local account for installing Windows, he will e prompted to create three security questions that can be used to reset the password and log into the Windows 10 account in case there is any misfortune. However, if you do not have much use for these Security Questions, then you can definitely have them disabled using a simple PowerShell script which you can download from GitHub. For more details on how to disable security questions in a Windows 10 machine, refer to the steps provided below. Step 1: You need to first download the .ps1 file from the GitHub repository. Step 2: Once you’ve downloaded the file, open the PowerShell window with admin privileges. Step 3: After that, navigate to the folder where you had saved the .ps1 file. Then copy the address of the folder location. Step 4: Next, change the directory by using the following command:

cd "folder location address"

Step 5: After that, enter the following script to disable the security questions:

Update-AllUsersQA

Once you’ve completed the steps above, the Security Questions should be disabled and you will be notified with a message stating that the feature has been disabled. On the other hand, if you have a change of heart and you want to enable the Security Questions back, here are some steps you need to take: Step 1: First, open the PowerShell window as admin. Step 2: Next, run the same script with one more parameter such as:

Update-AllUsersQA -answer SecretAnswer

Step 3: And that’s about it. Do not forget to replace the Secret Answer with your preferred one and once you’re done, it will be set as the answer for all the Security Questions. Step 4: Now all that’s left to do is go to the Settings app to change the answer to the questions and you should be good to go.

When Windows 10 was introduced as an upgrade to Windows 7 and 8, a lot were thrilled because of its new features. One of the most interesting features that this has is the Microsoft Store. Just like in our tablets and smartphones, we can now download our favorite apps from a trusted source. Without the Microsoft store app, you can’t download any applications that you can use on your computer. But what happens if you can’t open your Microsoft Store or you accidentally uninstalled it? The most common error that users encounter when accessing Microsoft Store is the error code 0x80072efd. This error code appears when there is a problem with the internet connection. To resolve this, troubleshoot your modem by doing a simple power cycle. Turn off your modem and wait for a couple of minutes and turn it back on. It should refresh your internet. This works if there is really no problem on the Service provider’s side. Disable your Proxy server, if you are using one to access the internet. To do this, press Windows + R keys on your keyboard. Type “inetcpl.cpl” in the box and go to Connection. Next, click on LAN settings then tick on the box next to Automatically detect settings. Uncheck the box below Proxy Server Among the useful apps that came with the Windows 10 upgrade is PowerShell. It allows you to install and uninstall individual and all apps by using a series of commands. So you don’t have to worry if you can’t find your Microsoft Store or if you accidentally delete it. To access PowerShell, type in the word PowerShell into the search box found beside your Window Icon. Look for PowerShell from the results and right-click on it and hit Run as Administrator.

When you are in the PowerShell window, enter the command below:

Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"

Another option is to download a Windows Update Troubleshooter. After you download it, open the troubleshooter tool and follow the steps. If you saved the file instead of directly opening it, go to the folder where the troubleshooter was saved and double click on the wu.diagcab file to rub the troubleshooter. One of the most interesting error codes that you might encounter when accessing the Microsoft store is error code 1. This particular error code is resolved by changing your PC’s region to the United States. To do this, go to Settings and look for Time & Language. Then go to region and language. Under the Country or region, choose the United States from the dropdown menu then restart your computer. The troubleshooting procedures above are the most common solution to resolve the problem on Microsoft Store issues but there are times that these procedures won’t work. If you are not confident to resolve this through the procedures mentioned in this article, there are so many tools online that you can download to help you out. It also helps to contact Microsoft or consult a technician to ensure that you are doing the correct procedure.

It has been some time since the release of Diablo 2 resurrected and overall reception was pretty good. People are enjoying the old classic game in hi-def. resolution and with new and improved visuals. Sadly some server issues are present still until this day and somewhat spoil the experience for players. The greatest lag and server crashes are pinpointed to game-creating events. When a player creates a new online game, the server needs to pull a lot of details from the database and make a game, due to some legacy code present this process takes some time and it is demanding a bit on the server-side, and although code was optimized to cater to more modern approach some legacy code still remains. Another thing that was spotted to affect performance itself is player behavior, to be more specific, modern gamer behavior. Where players find good builds and runs on the internet and then go to farm-specific areas or bosses for loot or experience points, which in return boils down to making plenty and short runs that are made by creating games and after run eliminating them. Now pair that with the previous statement about legacy server and database code and you can add 1 and 1 and see how this might be an issue. A lot of short games over legacy code are placing games in a state it was not designed for back in 2001 and therefore we have issues. Sadly solutions without completely rewriting the whole code are not very promising and they include rate limiting, which will prevent players to create many games in succession in a short period of time and maybe even login queues to drop a load on servers. Blizzard reached to people in the whole company, even old diablo 2 developers to ask for advice and they say that they are working on solutions so they could lift limitations and have everything running fine.

The Google Chrome browser checks the SSL Security Certificate of the website that you are trying to open. However, if Chrome is not able to check the certificate then you might encounter an error related to the SSL Certificates which you might face when browsing the web. This particular error is the ERR BAD SSL CLIENT AUTH CERT error which is caused by many factors such as the computer’s Time, Cached Data is corrupt, Date is out of sync, as well as third party software installed in your computer is the one that’s blocking the site and many more. The ERR_BAD_SSL_CLIENT_AUTH_CERT error might also be coming from the website’s end. It could be that the server is rejecting the certificate the client website is sending. The certificate might have already expired or the server may not trust its issuer – whichever the case may be, here are some options you can check out to fix the error.

Option 1 – Sync Date and Time

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the ERR_BAD_SSL_CLIENT_AUTH_CERT error. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.

• Right-click on the Taskbar and click on the Adjust Date and Time option.
• Next, click on the Sync Now button to synchronize the Date and Time with the Microsoft Servers.
• Now make sure that the Time Zone that’s set on the same page is correct.

Option 2 – Try clearing the browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BAD_SSL_CLIENT_AUTH_CERT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.

Option 3 – Try to check and fix any possible conflicts with third-party programs

Third-party programs like internet protection software could be interrupting the connection and causing the error. For some unknown reason, your antivirus program or firewall might be detecting the webpage you are trying to open as malicious or with less credibility which is why it is blocking the browser from opening the website. To fix that, if you have third-party programs installed like VPN, security software, or any add-on, or firewall, you can disable them temporarily and see if it fixes the problem and you’re able to pull up the website. After a while, you have to enable them back and configure their settings so that the website won’t get blocked again.

Option 4 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR_BAD_SSL_CLIENT_AUTH_CERT error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
• Restart the browser.

On the other hand, if you were using Firefox when you go the error, here’s what you have to do.

• Open Firefox and in the address bar, type “about:config” and hit Enter.
• If a warning appears, just click on the “I accept the risk!” button to proceed.
• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

Option 5 – Try to update Google Chrome

You might also want to try updating your browser to its latest version and have it installed in your computer. After you install the update, check if you can now open the website you were trying to open earlier.

Option 6 – Get rid of any conflicting browser extensions

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.
• To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.
