A Simple Guide to Fixing Error Code 0x80070424

If you suddenly find the middle mouse button not working as you use it on your Windows 10 computer, then you’ve come to the right place as this post will provide some suggestions that can help you fix the issue. This kind of problem can affect your experience in using your computer as the middle mouse button helps you in scrolling through long web pages and screens with a lot of data. So if that stops, you will end up using your keyboard instead which is kind of a hassle compared to using the middle mouse button. It is possible that this problem could have something to do with either the hardware or software. To isolate the possibility of a hardware failure, you can try to connect the mouse to a different computer and see if it works just fine there or if it still has the same problem. If the mouse works properly on a different computer, then the issue is software-related. It is possible that a software update, especially gaming software, could have been misconfigured in a way that the middle button does not respond like it’s supposed to. To resolve the problem, you might want to try reinstalling or updating the mouse drivers or run the Hardware and Devices troubleshooter. You can also install OEM-specific mouse drivers or modify some entries in the Windows Registry.

Option 1 – Reinstall or update the Mouse driver

The problem may be caused by a corrupted or an outdated mouse driver. To fix it, you have to update or reinstall the mouse driver. How? Follow these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the Mouse and other pointing devices and right-click on the mouse driver to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, disconnect the mouse and plug it back in to reinstall the mouse driver.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 2 – Try running the Hardware Troubleshooter

The next thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to 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 3 – Try to install OEM specific mouse drivers

Aside from updating or reinstalling the mouse drivers, you might also want to try installing OEM-specific mouse drivers. When you install Windows, it will use a generic driver for all its components. The disadvantage of generic drivers for the mouse is that it limits its functionality. In fact, some also configure the middle mouse button to respond to specific action which does not work without the correct drivers. In such cases, you need to visit the website of your computer’s manufacturers to download and install the latest drivers and then open the software and configure it the way it was before. Keep in mind that some OEMs also offer gestures, so you also have to check on that.

Option 4 – Try to modify some entries in the Registry

If a Windows Update is the one that caused the problem, you could correct it by making some modifications in the Registry but before you proceed, make sure that you create a System Restore point first.

• Tap the Win + R keys to open the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERControl PanelDesktop
• After that, double click on the “WheelScrollLines” entry on the right pane to open its Properties.
• Now change its value data to “3” and exit the Registry Editor and then see if the issue with the middle mouse button is fixed or not.

California's Department of Fair Employment & Housing has widened its anti-discrimination lawsuit against Activision Blizzard and claims the publisher has been shredding vital documents relevant to the ongoing investigation. A recent report from Kotaku described the department as offering poorly paid, highly insecure positions, with a culture of hostility towards LGBTQ+ testers. The DFEH's rewording of "employees" to "workers" now hopes to take these contractors' experiences into account. "As a contract employee, I feel there's a lot of pressure to excel, impress, and move through the ranks as fast as you can before your contract ends and you're forced to go 3 months without income or find another job," Axios reports one worker saying. "I take pride in what I do, but it feels like it's never enough." Activision's contentious hiring of union-busting third-party law firm WilmerHale "directly interferes" with its own investigation, it says. By going to WilmerHale, Activision appears to be claiming that all work related to the investigation is privileged and can't be shared with DFEH. The suit also claims that Activision HR shredded documents related to "investigations and complaints", against its legal obligation to retain them during the investigation. The relevant parts of the updated lawsuit were shared by Axios reporters Stephen Totilo and Megan Farokhmanesh, the former also noting that the DFEH "fixed their misspelling of Bill Cosby's name". "DFEH is also informed and aware that documents and records have not been maintained as required by law or by the DFEH's Document Retention Notice," the complaint reads, "including but not limited to documents related to investigations and complaints were shredded by human resource personnel and emails are deleted thirty days after an employees separation."

Speculation and answer from Activision Blizzard

Blizzard employee Jessica Gonzalez suspects that the costs of fines associated with destroying these documents may have been an easier blow for Blizzard to take than any penalties drawn from their existence in helping the lawsuit go through. In an email to Kotaku, Activision denied the shredding allegations and issued a statement outlining steps it had taken to improve company culture—including the ousting of high-level executives like Blizzard president J. Allen Brack. The full statement reads: "Throughout our engagement with the DFEH, we have complied with every proper request in support of its review even as we had been implementing reforms to ensure our workplaces are welcoming and safe for every employee. Those changes continue today, and include:

•     Several high-level personnel changes
•     Revamped hiring and recruiting practices requiring diverse interview panels
•     Greater transparency on pay equity
•     Expanded and improved training and investigative capabilities for human resource and compliance staff
•     Created investigation teams outside of business units to support greater independence
•     Restructured divisions to support greater accountability
•     Enhanced review processes to include evaluation of managers by employees
•     Clear boundaries on workplace behavior with a zero-tolerance approach to harassment and other actions that diminish or marginalize.

"We strive to be a company that recognizes and celebrates the diverse talents and perspectives that lead to the creation of great, globally appealing entertainment. We have provided the DFEH with clear evidence that we do not have gender pay or promotion disparities. Our senior leadership is increasingly diverse, with a growing number of women in key leadership roles across the company. "We share DFEH’s goal of a safe, inclusive workplace that rewards employees equitably and is committed to setting an example that others can follow."

California and RIOT

Beyond Activision Blizzard, California's DFEH has also probed into League of Legends creator Riot Games, accusing the studio of dragging its heels over sexual harassment allegations dating back to 2019. Riot denied the allegations, telling us that it "will never retaliate against anyone for talking to any government agency".

The Winload.efi file is an Extensible Firmware Interface or EFI file. EFI files are executable files for the firmware of the computers that are mainly based on UEFI and execute the tasks of loading the files to the bootloader of the computer. They are used for a specific set of tasks such as turning on the computer, installing Windows, restarting the computer or resetting it, and so on. This is why the Winload.efi file is a significant file so if it gets corrupted, lost, or damaged, it would be impossible for the Windows operating system to proceed. Here are some errors you can encounter that are related to the Winload.efi file:

Option 2 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve errors related to the Winload.efi file. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.

This should launch and load Windows on your PC with the Early Anti-malware protection disabled for that session only when you try to carry out the same task and then check if the error related to the Winload.efi file is now fixed.

Cache files are temporary files that have been created by various applications and services when used.  As temporary files, they are safe to be removed and deleted from the system since the application or service will create new ones when needed but sadly will not remove old ones, this task is left to OS itself. Automatic Windows cleanups can mostly take care of these things but for top-notch performance clearing cache manually is a far better option. We will here explore various cache temporary files, where they are, and how to clean them. Sit back and let’s do some cleaning!

Clear cache using Disk Cleanup

1. Open Start menu and search Disk Cleanup
2. Click on it in search results
3. Click on the drives drop-down menu and select the drive where is Windows 11 installed
4. In the Files to Delete section enable all boxes and click on OK
5. Click on delete Files to confirm

Clear Microsoft store cache

1. Press ⊞ WINDOWS + R to open the run dialog
2. Type in WSReset.exe and press ENTER
3. Black blank windows will appear, wait for the window to close itself and you are done

Clearing location cache

1. Press ⊞ WINDOWS + I to open location history
2. Select Privacy & Security
3. In the App Permissions section click on Location
4. On-Location page click on Clear

Clear and flush DNS

1. Press Start and search for Windows Terminal
2. Click on Terminal in search results
3. Type in: ipconfig /flushdns and press ENTER

And that is that!

The third time is charm saying goes but not when we are talking about Microsoft. Print spooler is again in focus, in a bad way. This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw came to light shortly after and was subsequently patched (with mixed success). Microsoft is once again advising its customers to disable Windows print spooler after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

"An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights."

Stop this service right away or you are risking a potential attack.

1. Press ⊞ WINDOWS + X to open the hidden menu
2. Click on Power Shell (admin)
3. In Power Shell type in the following command to check if spool service is running: Get-Service -Name Spooler followed by ENTER
4. If spooler service is running type in the next command to stop it: Stop-Service -Name Spooler –Force and press ENTER
5. Then follow with this command to disable it at startup: Set-Service -Name Spooler -StartupType Disabled followed with ENTER

That’s it, we hope a patch will come soon for all the people that are using network printing and indeed need this service running in order to do work.

A very serious data breach has happened to the unfortunate GoDaddy hosting service placing a little over 1.2 million accounts affected. Security breaches sadly are not a rare occurrence but this time it is a little different. Each time when the company is breached data is stolen and that places the company in a bad light usually because its user database has been compromised and people are concerned about their data being misused. This is very rational fear and concern but this time things are a little bit different than usual, why is that, you might ask? Well, as before mentioned GoDaddy is a hosting company and the vector of attack was aimed at the part where it is hosting WordPress. Attackers were able to get their hands on the sFTP credentials of customers on that server meaning that all of the websites are also been relieved of their user base as well. This potentially means that there is a high chance that all of the hosted web site's content is also compromised, meaning that your data could also be compromised even if you were not a GoDaddy customer, all you needed to do is to be a member of any site hosted on their platform. GoDaddy has reset WordPress passwords and private keys, so it’s already taken the steps required to stock the attacker from exploiting anything with the passwords obtained. The company is in the process of generating new SSL certificates for customers. Bad thing is that the attack used a compromised password to get into systems all the way back around September 6^th, 2021, the breach was discovered on November 17^th, 2021, which is more than a 2-month active time where the attacker could harvest tons of data. The outcome of this attack will be seen in the upcoming time, until then be safe, and Just in case change your passwords.

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.

As you know, Windows 10 is equipped with a Mobile Hotspot feature that allows users to share the existing internet connections to other devices over Wi-Fi. However, one of the downsides to this feature is that it does not stay on if there are no devices connected to it for over five minutes. In other words, if there are no devices connected to the mobile hotspot for five minutes, it will turn off automatically. Thus, if you want the mobile hotspot to stay turned on, then you’ve come to the right place as this post will walk you through how to stop the Mobile Hotspot from turning off in Windows 10. There are two scenarios tackled in this post wherein the Mobile Hotspot feature turns off automatically and where the hotspot disables when there is no internet connection. To remedy these scenarios, you can try turning off the power saving feature or use a PowerShell command to change the “PeerlessTimeoutEnabled” settings or increase the Mobile Hotspot idle timeout settings. You could also increase the timeout period when a cellular connection is not available or disable the Wi-Fi and network adapter power management options. For detailed instructions, refer to each one of the given options below.

Option 1 – Try turning off the power saving feature

The first solution you can check out is to turn off the power-saving feature. To do so, follow these steps:

• Open the Settings app and go to Network & Internet and from there, click on the Mobile Hotspot option.
• Next, toggle the “Share my Internet connection with other devices” option.
• After that, toggle the “When no devices are connected, automatically turn off mobile hotspot” option.

Option 2 – Execute a command in PowerShell

The next option you can try to keep the mobile hotspot turned on is through a command in PowerShell. To get started, follow these steps:

• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option.
• Next, execute the following command to make sure that the Mobile Hotspot stays on even when no devices are connected to it:

powershell -windowstyle hidden -command "Start-Process cmd -ArgumentList '/s,/c,net stop "icssvc" & REG ADD "HKLMSYSTEMCurrentControlSetServicesicssvcSettings" /V PeerlessTimeoutEnabled /T REG_DWORD /D 0 /F & net start "icssvc"' -Verb runAs"

• After the command is executed, here is what the script is doing in the background:
  • It stops the Mobile Hotspot service (icssvc).
  • It navigates to this registry path (HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesicssvcSettings) and creates a DWORD key named “PeerlessTimeoutEnabled” which has a value of 0.

• It then restarts the Mobile Hotspot Service (icssvc).

Option 3 – Try increasing the Mobile Hotspot idle timeout settings

Another option you can try is to increase the idle timeout settings of the mobile hotspot. In case you don’t know, the default timeout when there’s no active connection is about five minutes. So if you don’t want to keep it on always but want to keep it on longer than five minutes, then this option is for you. All you have to do is change the same key (PeerlessTimeout) as mentioned above, at a different location. In fact, you can change it to a maximum of 120 minutes. To give this a try, follow these steps:

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSystemControlSet001ServicesICSSVCSettingsPeerlessTimeout
• From there, change its value to anywhere between 1 up to 120.
• Once done, exit the Registry Editor and restart your computer.

Option 4 – Try increasing the timeout period when a cellular connection is not available

There are many times when you want to connect devices so it becomes part of the network. And as pointed out, the Mobile Hotspot turns off automatically when there is no internet or mobile data but when you use a registry setting, you can change any value between 1 and 60 inclusive.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSystemControlSet001ServicesICSSVCSettingsPublicConnectionTimeout
• From there, set the value of the “Timeout” key between 1 and 60.
• After that, close the Registry Editor and restart your PC.

Option 5 – Try to disable the Wi-Fi and Network adapter in Power Management options

As you know, the Wi-Fi adapter and the network devices have properties that will turn off when on battery and when it’s not used for a long time so you can try to disable these options.

• Tap the Win + X + M keys to open the Device Manager.
• Next, expand the list of Network devices and select the Wi-Fi adapter.
• After that, go to the Power Management tab and make sure that anything related to power saving should be turned off. This will ensure that none of the network devices will turn off the Mobile Hotspot or trigger anything that will do that.
