Fix Lost internet connection in Windows 10

As of late, a number of users reported experiencing a problem where their Windows 10 computers get stuck on Airplane mode for some unknown reason. According to the affected users, they were unable to turn off the Airplane mode which means that their computers are also not able to connect to the internet. One of the possible reasons why this kind of issue occurs is that there could be a bug with the airplane mode or it could also be the doing of faulty network drivers or physical switch that’s turned on, and so on. If you are one of the few users who experience the same issue, then read on as this post will guide you on what to do if your Windows 10 computer gets stuck on Airplane mode. There are a couple of suggestions you can check out to resolve the problem. You can try to check the status of the Radio Management service, flush the DNS cache or you could turn off the airplane mode via system settings. You could also update the network drivers or turn off the physical switch for airplane mode or make some adjustments in the Windows Registry. For more details, refer to each one of the suggestions provided below.

Option 1 – Try to check the Radio Management Service status

• First, tap the Win + R keys to open the Run dialog box and type “services.msc” in the field, and hit Enter to open the Windows Services Manager.
• Next, look for the Radio Management service and select Properties.
• From there, change its Startup type to Disabled and click on the Apply and OK buttons to save the changes made.
• Once done, restart your computer and check if you can now turn off the airplane mode.

Option 2 – Flush the DNS cache

You could also try to flush the DNS cache to fix the “ERR_ICAN_NAME_COLLISION” error. All you have to do is open Command Prompt as an administrator and then execute each one of the following commands sequentially to flush the DNS cache:

• ipconfig/release
• ipconfig/renew
• ipconfig/flushdns

Option 3 – Try turning off the airplane mode via System settings

If flushing the DNS cache did not help in fixing the problem, then you might want to turn off airplane mode via system settings.

• In the Windows Search bar, type “airplane mode”.
• From the search results that appear, click on Airplane mode.
• After that, a window will appear where you have to turn off the toggle button for Airplane mode.

Option 4 – Try to update, rollback or reinstall the Network adapter drivers

The next thing you can do to resolve the problem is to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
• Look for the Broadcom Network Adapter and right-click on it, as well as other network adapters that have an exclamation icon, and update them all.
• Restart your PC and see if it helped in fixing the problem.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to roll back the very same drivers from their previous versions and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly. To reinstall the network adapter drivers, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them 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, restart your computer. It will just reinstall the device drivers automatically.

Option 5 – Try to turn off the physical switch for Airplane mode

If your computer has a physical switch to turn on or off the airplane mode, then you might want to check that switch if you have one. Chances are, it could be the reason why you’re unable to turn off Airplane mode on your computer.

Option 6 – Try to make some adjustments in the Registry

• Tap the Win + R keys to launch the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESystemCurrentControlSetControlClass
• From there, edit the registry value of “RadioEnable” to “1”.
• Exit the Registry Editor once done, and restart your computer.

If you like to schedule different tasks on your Windows 10 computer and automate them, then you would find the Windows Task Scheduler very useful. It is commonly used by a lot of users to schedule various tasks like scheduling periodic execution of scripts and some programs to make sure that the intended tasks are automatically carried out. Apart from being a preinstalled application, the Task Scheduler is already available on your computer. However, there are times when you might encounter some errors while using it. One of these errors is error 0xFFFD0000. You can encounter this error while executing some PowerShell scripts. It can occur to any tasks as well especially to the ones that have a file executed using a particular program. And just like the PowerShell script, files also use PowerShell to be executed. To fix Error 0xFFFD0000, you need to follow the instructions provided below carefully. Step 1: In the Start Search, type “task scheduler” and click on Task Scheduler from the results to open it. Step 2: After opening Task Scheduler, right-click on the task that’s giving you the error and then click on Properties. Step 3: After that, navigate to the Actions tab in the new mini window that appears. Step 4: From there, select the action for the task and click on the Edit button which will open another mini window. Step 5: Next, make sure that the path to the executing program is properly typed inside the field of Program/script. Note that it should be set to the executable file for that particular program. For instance, you have to set it to “C:WindowsSystem32WindowsPowerShellv1.0powershell.exe” for the Windows PowerShell program. Step 6: You can also utilize the Browse button and navigate through Windows Explorer to locate that particular executable file for the program. Step 7: Now make sure to use the file argument in the Add arguments field followed by the path of the file to be executed. It should look like this:

-file "C:/Users/Ayush/Desktop/Powershell Script Sample.ps1"

Step 8: Once done, click on OK to save the changes made and see if the task is still giving you an error or not. On the other hand, if you are still getting the same error, you can try to repair the Task Scheduler by deleting corrupted tasks. Note that a single corrupted file can cause big problems so this option is quite important. And for you to delete a corrupted task or any task from the Task Scheduler, you have to use the Registry Editor if you are not able to use the Task Scheduler interface. To do so, follow these steps:

• Tap the Win + R keys to open the dialog box for Run.
• Next, type in regedit and click on OK or tap Enter to open the Registry Editor.
• Then navigate to this path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTree

Note: In this path, you can see all the tasks that are currently set in the Task Scheduler. And since it would be hard to tell which one of them is corrupted, you have to delete the latest one in Task Scheduler last. But before you do so, make sure that you take a note of the ID of the tasks. And for you to get the ID, you have to select the task you wish to delete and double click on the ID string located on your right-hand side, and then copy it in the Notepad.

• Right-click on the task name and then delete it.
• After that, delete the very same GUID which you have copied earlier from these folders:
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheBoot
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheLogon
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheMaintenance
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCachePlain
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTasks

Note: You might not see the same GUID from these folders but if you see it, delete it right away.

• Next, navigate to this location: C:WindowsSystem32Tasks
• Delete the very same tasks you just deleted from the Registry Editor.
• Restart your PC and check if the Task Scheduler is back to its normal state or not.

Error Code 0x80070004 on Windows 10 – What Is It?

Some users trying to upgrade from Windows 7 or Windows 8/8.1 reported experiencing installation rollback with error code 0x80070004. This error normally appears when the Computer Name is set to names that can’t be used for the computer. It’s also possible this error occurs if users or program files folder were redirected to a different partition.

Solution

Error Causes

The Error code 0x80070004 on Windows 10 is normally caused if any of the following were used as the Computer Name and the user tried to upgrade to Windows 10:

• System (or SYSTEM)
• SELF
• LOCAL
• Network

Failure to fix this error message might result in others, including error code  0xc0000001. 

Further Information and Manual Repair

If you don’t solve this error, you won’t be able to upgrade from Windows 7 or Windows 8/8.1 to Windows 10. Note that this error will continuously bring you back to the original OS unless fixed.

Please note that if you’re not confident in doing these steps, you might want to consider seeking the help of an expert or using an automated tool that will help fix this.

Here are a few methods to try.

Method 1: Check and Change the Computer Name

The most common cause of this error is if your computer uses any of the following reserved names:

• LOCAL
• System (or SYSTEM)
• Network
• SELF

These reserved names are not meant to be used as computer names. If this is what your computer uses and you try to upgrade to Windows 10, you will surely get this error. Check your computer name and if you see any of the reserved names, change it right away.

Changing Computer Name in Windows 8.1

If you’re trying to upgrade from Windows 8.1, you can change the name of the computer by following these steps:

• Step 1: Open the Start menu then simply type “rename computer”. After that, choose “Rename this computer”
• Step 2: A dialog box will open. Just click the “Change” button
• Step 3: A new dialog box will open. Type the new name. Click Apply then Ok.

Changing Computer Name in Windows 7

If you’re trying to upgrade from Windows, you can follow the steps below to change the name of your computer.

• Step 1: Go to the Start menu then on the Computer section, right-click the mouse and choose “Properties”.
• Step 2: A new dialog box will appear. Go to “Computer name, domain, and workgroup settings” then click “Change settings”. In case you’re asked for administrative access, make sure to grant it.
• Step 3: Find the “Computer Name” tab then click “Change”
• Step 4: Change the computer name and click Ok.

Method 2: Fix the “Users” directory issue

If the first method doesn't work, it probably means the computer name isn’t the cause of this error. Another reason why users experience Error code 0x80070004 when upgrading to Windows 10 is if the “Users” directory was relocated. So, when you try upgrading to Windows 10, the installer wasn’t able to find the user profiles on the “%systemdrive%”, where the current operating system is installed.

If you changed or moved any of the Users, Program Data, or Program Files folders, this will cause the error. Before you upgrade to Windows 10, you might be required to reset or reinstall your current operating system (Windows 7 or Windows 8.1).

If you haven’t made any changes or haven’t moved any of the mentioned folders, there’s a great chance that your users' profiles are corrupted. You can also reinstall your current operating system. However, you might want to check for the corrupter user profile first. To do this, follow the steps below:

• Step 1: Go to the Start menu and type System
• Step 2: Click System  then go to the Advanced tab
• Step 3: Go to Settings, which you’ll find under User Profiles

On the Users Profiles, make a copy of all the accounts somewhere. Sign out from the current user account then try logging in back using the accounts you’ve copied. For each account, you get an error, delete it. However, make sure that you don’t delete the UpdateUser and Administrator account ever.

After this is done, try upgrading your operating system to windows 10 again.

Method 3: Try a trusted and secured Automated Tool

If the above methods still not useful, you might want to rely on an automated tool. Find a secured and trusted tool. It will help fix this issue.

Error Code 0xC004C4AE - What is it?

Activation errors in Windows 10 can interfere with your ability to fully use the system. When Error Code 0xC004C4AE appears on your computer, you may see a message that shows that the validation process has been stalled due to binaries that appear to have been tampered with.

The Windows 10 operating system utilizes a variety of measures in order to track your app launches so that it can boost both your start and search results. It can personalize the start menu based on the apps that you use the most on the Start menu as well as the search results. This way, the App Launch Tracking is definitely useful especially when you want to access your favorite and frequently used apps quickly in the Start menu and search results on your Windows 10 computer. On the other hand, Windows 10 provides users with the ability to control their privacy settings in order to protect the privacy of users. Windows 10 users can either opt to enable the app launch tracking to improve the start menu and search menu or opt to disable the app launch tracking in order to prevent the Windows operating system from tracking that you open if you really value your privacy that much.

In any Windows operating system, Safe Mode is definitely a special environment used for troubleshooting issues as well as system diagnostics. Safe Mode allows you to remove any malware in your computer and troubleshoot issues that can’t be fixed when you’re in desktop mode. This is why Microsoft made sure that the Safe Mode option is not available directly and can only be accessed by pressing function keys such as F2, F8 (depends on what PC you are using) or via MSConfig. To make it easier for you to access Safe Mode, this post will guide you on how you can add Safe Mode to the Boot Menu options in Windows 10. As you know, Windows 10 now has Advanced Startup options that allow you to boot directly into Safe Mode without having to restart your PC and then tapping the special key a couple of times. However, if you really have to always use Safe Mode, it’s best to add it in the Boot Menu options. To do that, simply follow the steps below.

• Select Command Prompt (Admin) option from the WinX menu to open Command Prompt with administrator privileges.
• After opening Command Prompt, type the bcdedit /copy {current} /d "Safe Mode" command and hit Enter.
• Once the command is executed, you will see a message saying, “The entry was successfully copied to {74a93982-9486-11e8-99df-00270e0f0e59}”. This message indicates that Safe Mode was successfully added in the Boot menu option which means that you can now directly access it and boot your Windows 10 PC in that mode.

To check if Safe Mode was really added in the Boot menu options, you have to open Msconfig. From there, you will also have to use it to configure the boot settings for the Safe Mode entry. To do so, follow the given steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “MSConfig” in the field and click OK.
• Next, go to the Boot tab and find the Safe Mode option which should be located under the default Windows 10 mode.
• Afterward, you need to select the Sage boot option and Minimal. You also have to select the Make all boot settings permanent option.
• Make sure to increase the timeout to at least 10 seconds which will ensure that the menu does not disappear right away.

Note: In similar steps as above, you can add the Safe Mode with Networking and Safe Mode with Command Prompt entries as well. Just simply select “Network” for Safe Mode with Networking and “Alternate Shell” for Safe Mode with Command Prompt. Once you’re done adding any of them, click on Apply and restart your PC. In addition, if you wish to remove the entry, you just have to open MSConfig again and select the entry you want to remove, and then click Delete.

The error code 0X8019019A is shown when a user fails to add his Yahoo account to the Mail app due to the outdated or corrupt installation of the Mail app. Not using an App-specific but a normal Yahoo account password may also result in the error at hand. In this guide, we will show you how to effectively fix this error so you can set up Yahoo mail.

1. Reboot PC

   Perform a restart of your system to rule out a temporary glitch in the system. Also, check if you can successfully access your email through a web browser using the same credentials as you are using with the Mail app. Additionally, make sure that no VPN or proxy server is being used to access the internet (VPN/proxy may work fine with the web version of Yahoo mail but may hinder the access through a mail client).

2. Update Windows and the Mail App to the Latest Build

   If your system is not updated to the latest build it can create incompatibility between the OS modules. Updating the Windows and Mail app of your system to the latest build may solve the problem.

3. Re-add the Yahoo Account to the Mail App

   The Yahoo account issue could be a result of a temporary glitch in the communication modules of the system. The glitch may get cleared if you remove and then re-add the Yahoo account to the Mail app.

4. Reset the Mail App to the Defaults

   You may fail to add the Yahoo account to the Mail app if the installation of Mail itself is corrupt. In this scenario, resetting the Mail app to the defaults may solve the problem.

5. Generate an App Password and Use it to Add the Yahoo Account to the Mail App

   Yahoo has implemented tons of security features to its accounts. One such feature is the use of app-specific passwords for less secure apps like the Mail app. If your Yahoo username or password is not working with the Mail app, then using the App-specific password may solve the problem.
