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.

Windows has tendencies to remember WIFI passwords so it can reconnect automatically to them. But from time to time we change passwords and Windows does not let us change it since he has network remembered. In this case, we will not be able to connect to the internet. In this helpful guide, we will let you know which steps you will need to take in order to solve this issue and to be able to connect to the internet again.

1. Restart Modem

   First thing first, restart your modem. Windows might see it as a new network and offer you to type in the password for it.

2. Update driver

   Sometimes the issue could be due to driver problems, open device manager and update WIFI driver or reinstall it.

3. Reset WIFI password

   Press ⊞ Windows + R type “Control” > hit Enter. Now click Network and Internet > Network and Sharing Center > Change adapter settings. Right-click on the connected Wifi and select Status. Click Wireless Properties, change the password from the Network security key section, and then click OK to reset your WiFi password.

4. Forget the network

   Click on Start > Settings > Network & Internet > Wi-Fi. Click the Manage known networks link Select the network you are looking for Select Forget.

5. Delete your WIFI profile

   Press ⊞ Windows + X to open the secret menu and click on Command prompt (admin) In command prompt windows type: netsh wlan show profile netsh wlan delete profile name=<profile name> Reboot

Device drivers are needed in order for the hardware and software to communicate in an operating system. Some of these drivers are digitally signed. These kinds of drivers are drivers that are signed by their issuing authority in a way that the end-user or any third party won’t be able to modify them. And there are times when you encounter an error that says, “Windows requires a digitally signed driver” when you try to install or update device drivers. Driver Signing is the process of associating a digital signature with a driver package. Digital signatures are used in Windows device installations to verify the identity of the vendor providing the driver packages as well as to verify the integrity of the driver packages. All the drivers you usually install on your PC from Windows Update, Original Equipment Manufacturers, or some other third-party driver download software and so on must be verified digitally by Microsoft through the digital signature. A digital signature is an electronic security mark that verifies the publisher for the driver and all the relevant information related to it. That’s why Windows won’t run a driver if it isn’t certified by Microsoft, be it a 32-bit or 64-bit system – this is called the Driver Signature Enforcement. The only Kernel-mode drivers that Windows 10 will load are the ones that are digitally signed by the Dev Portal. However, the changes only affect the new installations of the operating system with Secure Boot on while the non-upgraded fresh installations would require drivers that are signed by Microsoft. The “Windows requires a digitally signed driver” error indicates that the driver you are trying to update or install hasn’t been signed digitally by the issuing authority, preventing you from installing or updating it. To resolve this issue, you can try to update the drivers directly from the manufacturer’s site. You could also disable driver signing via Group Policy Editor.

Option 1 – Update the device drivers directly from the manufacturer’s site

The reason why you’re getting the “Windows requires a digitally signed driver” error in the first place is that you might have downloaded the drivers from external media. It could also be that the drivers didn’t update for some time now and the issuing authority changed its policies. Thus, you can try to update the drivers straight from the manufacturer’s website and install them. If this option didn’t work, then you’ll have to disable the driver signing or its recognition in Windows 10. Keep in mind that doing so is not advisable if you have to use the concerned driver.

Option 2 – Disable driver signing via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: User configuration > Administrative templates > System > Driver installation
• Next, double click on the “Code signing for device drivers” entry located on the right pane to open its properties where you’ll see the following description:

“This setting determines how the system responds when a user tries to install device driver files that are not digitally signed. It establishes the least secure response permitted on the systems of users in the group. Users can use the System in Control Panel to select a more secure setting, but when this setting is enabled, the system does not implement any setting less secure than the one the setting established. When you enable this setting, use the drop-down box to specify the desired response. “Ignore” directs the system to proceed with the installation even if it includes unsigned files. “Warn” notifies the user that files are not digitally signed and lets the user decide whether to stop or to proceed with the installation and whether to permit unsigned files to be installed. “Warn” is the default. “Block” directs the system to refuse to install unsigned files. As a result, the installation stops, and none of the files in the driver package are installed. To change driver file security without specifying a setting, use System in Control Panel. Right-click My Computer, click Properties, click the Hardware tab, and then click the Driver Signing button.”

• Now select the radio button for “Enabled” and select Ignore from the drop-down menu under “When Windows detects a driver file without a digital signature”.
• Then click on the Apply and OK buttons to save the changes made. This will get rid of the “Windows requires a digitally signed driver” error but take note that this will also make your system less secure.

DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files. In this post, we will be discussing one DLL file called ntdll.dll. It is described as “NT Layer DLL” which means that it contains some Kernel functions that help in the normal functioning of the Windows operating system. It is created by Windows in the System32 folder when the OS gets installed. This file can serve different programs simultaneously by providing them with different Kernel functions which support the programs’ performance. However, if you encounter the ntdll.dll file error on your Windows 10 computer, read on as this post will guide you in fixing the problem.

Option 1 – Try to re-register the ntdll.dll file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and un-register the OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /u ntdll.dll
  • exe ntdll.dll
• You should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Disable problematic Internet Explorer add-ons

There are instances when some add-ons in the Internet Explorer browser can cause the ntdll.dll file crash error. Thus, you need to disable some add-ons in Internet Explorer and then check if it fixes the problem.

Option 3 – Try running the DISM tool

You might want to repair potentially corrupted files in your system as having them could also trigger the ntdll.dll file crash error. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the DCOM error is now fixed.

Option 4 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

Option 5 – Try to replace the DLL file with a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:WindowsSystem32
  • x64: This PC > C:WindowsSysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 6 – Try scanning your computer using Windows Defender

The ntdll.dll file crash error might also be infected with malware or virus and to eliminate it, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

As you know, Microsoft’s consumer cloud storage platform is none other than OneDrive. It is where users can save any of their files albeit it’s mostly used to store common files like documents and photos. However, there are times when you might encounter some problems when saving these files. Recently, some users reported that they had problems saving Word documents to OneDrive and if you experience the same issue, then you’ve come to the right place as this post will guide you on how to resolve it. According to users who encountered the problem, when they try to save Word documents on OneDrive, an error message appears instead stating, “This is not a valid file name”. This kind of error only occurs when the file is opened from within OneDrive for saving in a different folder. In other words, if the file is saved in the same folder, the error won’t pop up but if it is saved in a separate folder, that’s when the error appears. Worry not though for fixing this error is not complicated and won’t take too long. It seems that this error is due to the 259-character limitation when creating and saving files as far as the Office products are concerned. To resolve it, there are several workarounds you can check out. Before you proceed with these workarounds, make sure that you have a stable internet connection.

Option 1 – Try renaming the file with a shorter name

The first thing you can do to fix the problem is to rename the file with a shorter name. Just right-click on the file and select the Rename option from the menu and then type in the new name and click OK or tap Enter to rename the file.

Option 2 – Try renaming the folders where the file is located

Like what you did in the first given option, all it takes is a right-click but this time on a folder. Rename the folder with a different name and save the changes made and then check if you can now save the Word document on OneDrive.

Option 3 – Try moving the file to a folder with a shorter path

If the first two options didn’t work, you can try moving the file to a folder with a shorter path. Note that it is not the same as doing it locally on a Windows 10 computer so you have to right-click on the file and select the “Move to” option. After that, locate the folder where you want to move the file and select it and then click on the Move button to complete the task.

Option 4 – Try making some changes in the document

You could also try to make some modifications to the document. Once you’ve done that, click the File tab and select the Save As option and then go to the folder where you want to save the file and tap enter.

Upgrading your Windows computer may not always go as expected as you could end up getting some error messages along the way. One of the error messages you can encounter is the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. This error indicates that is some security issue within the Windows operating system. It could be that the system files have an issue and they have been modified incorrectly. Although this does not necessarily mean that malware is behind the modification, one of the applications you installed recently might have something to do with the problem. The application might have modified or corrupted some of the core system files. When you encounter this error, you will see a blue screen along with the following error message:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete) If you’d like to know more, you can search online later for this error: 0xc000021a”

This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.

Option 1 – Uninstall programs you installed lately

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Perform System Restore

Performing System Restore can also help you fix the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. 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.

Option 3 – Run the System File Checker or SFC scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why you’re getting the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Rebuild the BCD and fix MBR

Rebuilding the BCD can help you in fixing the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• Next, select Command Prompt and type in the commands below one by one, and tap Enter right after you do so.
• exe /FixMbr
• exe /FixBoot
  • exe /RebuildBcd

The commands you entered should rebuild the BCD and repair MBR.

Option 5 – Run the CHKDSK utility

You can also run the Chkdsk utility to resolve the problem. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them.
• chkntfs /t
• chkntfs /t:10

If you are facing a missing sechost.dll error in your Windows 10, welcome, you have come to the right place to solve it and get back your computer in working order. Sechost.dll is a file that allows other programs to function and complete their tasks as well as control and change the behavior of other programs. The file is found in Windows subfolder System32, it is a completely safe file and should not be deleted. Sometimes however various other reasons can corrupt it or delete it. This guide will lead you to common solutions on how to get file back up and running.

1. Update device driver

   Have you installed a new device and all of a sudden you get the error message that Sechost is missing? Update device driver, it is possible that the file has been corrupted or replaced with an older version and therefore reported as missing. Update device driver to lastest version and issue should run away.

2. Re-register file via command prompt

   If Sechost got corrupted re-registering will solve the issue, press ⊞ WINDOWS + X and choose Command prompt (administrator), click on it. type regsvr32 sechost.dll and press ENTER Reboot your PC

3. Reinstall application

   Usually, Sechost gone bad or missing is due to the installation of another application that corrupts the file. Reinstall the application to try to solve errors. In order to properly reinstall the application first use the control panel to remove it completely from the system and then install it again, hopefully, this time correct version of Sechost.dll will be installed in the system.

4. Check your hard drive

   In some cases, a hard drive malfunction can cause several files to be corrupted or gone missing. To eliminate hard drive malfunction run check disk from Windows on C drive to check it and find if there are any errors.

5. Uninstall Windows update

   Same as with some application, even Windows update could corrupt some files due to update not being properly downloaded. Try uninstalling the latest update and revert to the previous Windows state, then update it again.

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.

There are a lot of reasons to ban or block different websites in your Windows. From wanting to limit yourself from distraction to block certain sites for sake of kids not going into them. Whatever your reason might be, keep reading in order to find out how you can block any website inside Windows for all browsers. The technique I am going to share with you is universal and not tied to Windows versions, they will work in any Windows from XP onward. Also, the technique will block desired websites on any browser, already installed or even ones that will be installed after doing the trick. And we will also be looking at applications that can help you in this task if you do not wish to do it manually.

Block websites using dedicated software

A small free application called Focal Filter which can be found here: https://www.focalfilter.com/ is a software solution for your needs. It is a pretty straightforward and easy-to-understand application and not really much can be said here about it. You simply download and install it, set your websites, and you are done, the app does rest.

Blocking manually via host file

Another method besides mentioned one using the dedicating application is to manually set site addresses inside the Windows host file. The first thing, of course, is to open the host file, run a notepad with administrator privileges, go to file open, and navigate to c:\windows\system32\drivers\etc\hosts. Once the file is opened go all the way down and add: 127.0.0.1 SITENAME For example: 127.0.0.1 www.youtube.com or 127.0.0.1 www.facebook.com This way each time user on a PC tries to access a listed website computer will reroute it to the given address which is your PC's local address and asked website will not be able to load.

Windows 11 comes with glass and transparency effects by default once it is installed. The transparency effect looks really good but if in any case, you do not like them, you can easily turn them off very easily

1. Open settings inside Windows 11
2. Inside settings click on Accessibility in the sidebar
3. Click on Visual Effects on far-right
4. Inside Visual effects, settings click on the switch beside Transparency effects to OFF

Windows will automatically save settings and apply changes right away. Just close your settings application and continue with work. You can always turn it back ON if you change your mind.
