Fix Hello Errors 0x801c004d or 0x80070490

The error code 0X8019019A is shown when a user fails to add his Yahoo account to the Mail app due to the outdated or corrupt installation of the Mail app.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.

A few days ago we celebrated fixing of months-long PrintNightmare vulnerability by Microsoft, sadly a new bug and issue have been found. Firstly discovered Microsoft stated:

A remote code execution 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.

A few days ago, Microsoft officially released a patch that was supposed to finally fix it. As you might recall this vulnerability was present for quite some time, Microsoft's solution after a long struggle was to elevate certain privileges to administrator account only and remove user accounts from managing printers. It complicated things a little bit but it was stated payoff was worth it. The new issue now is that on a system that already had accounts created and set, old accounts still can hijack the system, patch issues address only accounts that are created after the fix is administrated, old ones can still do whatever they want. Once again of course Microsoft has stated that until it is again resolved you should again disable the Print Spooler service as a temporary workaround.

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.

In today's time, Wi-Fi is a common occurrence, each household has it, on town squares, there are free Wi-Fi hotspots, etc. But sometimes when relaxing at home WI-Fi can fail on us and stop working. If this happens to you do not lose your mind because we have several troubleshooting help tips and ways to get it back quickly so you can continue with your browsing and using your internet.

Restart the Router and Computer

Yes, we will start with this typical cliche in IT and tech in general. Surprisingly this method still proves over and over again to be true and effective. Over time some electric components simply start working a little bit differently, electrostatic electricity can accumulate on some parts and they can cause issues. By turning off the device and leaving it for some time you are discharging accumulated electrostatics and placing it again into normal working mode.

Unplug your router and leave it for at least 30s like that, a full 1 min is recommended, and then plug it back. Turn it on and restart your computer in order to reboot addresses.

Reset DHCP

If simple have you tried unplugging it and plugging it back in did not work let us reset DHCP. Click on the start button and type in PowerShell, then click on Run as administrator. Once inside the PowerShell type in the following command followed by ENTER: ipconfig /release and after the command finishes, type in: ipconfig /renew also followed by ENTER key. Try the connection again.

Reset TCP/IP stack

The next thing that we will try if the previous one failed is to reset the TCP/IP stack to eliminate corruption of settings files. Like in the previous step, press Start and type in PowerShell and click on run as administrator. inside type in: netsh int IP reset and press ENTER key. Wait for the process to finish and reboot your PC.

Reset WinSock

WinSock is yet another part of Windows OS that is responsible for network communication and resetting it could solve the issue. Again go to PowerShell as described in previous steps and type in this time: winsock reset and press ENTER. Wait for the process to finish and restart your computer.

Other things you can try

Change TCP IP setting back to automatic if you have set manual Ip address on your computer.

Update your network driver via the manufacturer's website of your network adapter. There is a chance that somewhat updates are available to address some issues discovered.

Factory reset your router on the back by locating the reset button on it and pressing and holding it for around 10s.

Turn off your firewall and antivirus protection in order to eliminate it from blocking your internet access.

If you’ve tried resetting your Windows 10 computer using the Reset This PC option in order to restore your computer’s factory settings and the process suddenly fails for some reason and you got an error message instead stating, “There was a problem resetting your PC, No changes were made on your Windows 10 computer”, then this post might help you resolve the problem. Carefully follow each one of the options given below to resolve the “There was a problem resetting your PC error on Windows 10.

Option 1 – Try renaming the System and Software hive

• If you’re still able to boot to the desktop of your Windows 10 PC, open an elevated Command Prompt from the WinX menu.
• Now use the CD command and change the directory to Windows\System32\config folder. Simply type in the following command and hit Enter:

cd %windir%system32config

• After that, you have to rename the System and Software registry hives to “System.001” and “Software.001”, respectively. To do that, just type each one of the following commands and hit Enter after you type each of them.
  • ren system system.001
  • ren software software.001

On the other hand, if your Windows 10 PC isn’t able to boot to the desktop, you can just access Command Prompt from the Advanced Startup options or you can also boot into Sage Mode and open Command Prompt from there and then run the given commands above. Note: If you only want to use the Refresh your PC option, you must only rename System hive and not Software hive. On the other hand, if the Software hive is really corrupted, you might not be able to use the Refresh your PC option in such a case. Thus, you really need to rename the Software hive as well. Once you’ve renamed the Software hive, you won’t be able to use the Refresh your PC option but only the Reset your PC option.

• Type “exit” to close the Command Prompt and then restart your PC and try resetting your PC again.

Option 2 – Try to disable and re-enable the Windows Recovery Environment

If the first option didn’t help, you can try disabling the Windows Recovery Environment and then enable it back again. To configure a Windows Recovery Environment or Windows RE boot image and recovery options, you have to use the REAgentC.exe tool.

• Tap the Win + S key and type “REAgentC.exe” to open the REAgentC.exe tool.
• After that, type the following command and hit Enter to disable the Windows RE:

reagentc /disable

• After disabling the Windows RE, you need to enable it back by typing the following command:

reagentc /enable

Option 3 – Try to boot the USB recovery drive

If the two previous options failed, you need to try another workaround which is to boot to the USB recovery drive > Troubleshoot > Recover from a drive. From there, follow the on-screen instructions and you should be good to go.

As you know, Microsoft constantly releases new updates with the main goal of fixing bugs as well as deliver users with new and exciting features. However, there are times when the latest update comes with an unwanted bug. One of these bugs is an error message saying, “Low Disk Space. You are running out of disk space on Local Disk (G:). Click here to see if you can free space on this drive.” So if you have recently installed a Windows 10 update, then you’ll most likely see a completely new drive on your computer which will appear right after the installation of the update and you’ll also start seeing the aforementioned error message. It gets irritating as this error message keeps on popping up even if you still have a lot of free space on your other drivers. Obviously, the main reason why this error message pops up all the time is the bug brought along by the Windows Update. This bug unhides the recovery partition drive and allocates it a drive letter which is why you are seeing a new drive in your computer. Thus, you can get rid of the pesky error message by simply removing the letter of the new drive. Just remember that you must not delete anything from the recovery partition drive nor format the drive. Formatting or deleting the recovery partition drive can heavily affect the recovery of Windows since the data on the drive is used by the Windows Recovery Environment or your system’s manufacturer. A lot of users have reported that removing the drive letter has resolved the issue. And if you worry that removing the drive letter will delete the drive, you are mistaken. This solution is basically harmless and is proven effective to make the notifications go away. Carefully follow the instructions below to get rid of the Low Disk Space notification by removing the drive letter.

• Step 1: Tap the Windows key once.
• Step 2: Next. In the Windows Start Search, type in “command prompt” and right-click on Command Prompt from the search results and select the “Run as administrator” option or you could simply tap Win + R keys and then input “cmd” and hit Enter to open Command Prompt.
• Step 3: After opening Command Prompt, type in “diskpart” and tap Enter.
• Step 4: Next, type in “list volume” and tap Enter. After that, you will see a list of drives.
• Step 5: Take note of the letter associated with the newly created drive.
• Step 6: Afterwards, type in “select volume <drive letter>” and tap Enter. Take note that you must replace the <drive letter> with the drive letter you’ve found in Step 5.
• Step 7: Now type in “remove letter=<drive letter>” and then tap Enter. Once again, replace the <drive letter> with the letter you took note of in Step 5.

If you receive an error message saying, “Windows Update cannot currently check for updates because updates on this computer are controlled”, while trying to change the Windows Update preferences or manually update, then read on as this post will guide you in fixing it. You can mostly encounter this error in managed systems where an Administrator controls the permission on the operating system. The reason why you are not able to modify the Windows Update preferences or manually update your system is that a group policy prevents you from doing so and that the only user who can do these things is none other than the administrator of the system. Troubleshooting this kind of problem is the same as when you troubleshoot an error message that says, “Some settings are managed by your organization”. In such cases, you need to check both the Windows Update Group Policy and Registry settings. If you’re just a standard user, you have to contact your system administrator regarding this issue and if you are the administrator, you can make adjustments to the system settings via the Registry Editor and the Group Policy Editor. Refer to the instructions given below for detailed instructions.

Option 1 – via the Registry Editor

If you are using the Home edition of Windows 10 and you want to change the policy for non-admin users on your local computer, then you can use the Registry Editor for that. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows

• From there, look for the key named “WindowsUpdate” in the Windows folder and if it does not exist, you can just right-click on the Windows folder and select New > Key.
• Now name the new key “WindowsUpdate” and create a new sub-key under the newly created key and input “AU” as its name.
• Keep AU selected and then right-click anywhere in the right pane and select New > DWORD (32-bit) Value.
• Then name the Value as “AUOptions” and right-click on AUOptions and select Modify.
• Next, change the value of the Value data to “5” and click OK to save the changes made to the settings. Note that the Value Data of 5 refers to the policy to allow the local admin to choose the setting.
• Now restart your computer once you’re done and check if non-admin users can now modify the Windows Update settings or update Windows.

Option 2 – via Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and then type “gpedit.msc” and hit Enter to open the Group Policy Editor.
• Next, navigate to this folder: Computer Configuration > Administrative Templates > Windows Components > Windows Update.
• Now look for the “Configure Automatic Updates” policy on the right pane and double click on it to open its Properties.
• After that, shift the Radio button to “Enabled” and from the drop-down menu for Configure automatic updating, select option 5: Allow local admin to choose the setting.
• Then click on Apply and OK to save the changes made to the settings.
• Restart your computer and check if the problem’s fixed or not.

If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• 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.

• Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.
• From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. 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 following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 4 – Update the Device drivers

Updating the Device drivers can also help you fix the PFN_LIST_CORRUPT Blue Screen error. To do so, follow the steps below.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
• Then go to the Startup tab and select Microsoft OneDrive and then click Disable.
