The error code 0X8019019A is shown when a user fails to add his Yahoo account to the Mail app due to the outdated or corrupt installation of the Mail app.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

If you encounter an error saying, “error accessing the registry” when you try to merge a registry key on your Windows 10 computer, you’re not alone as some users also experienced the same problem. According to these users, they encounter the error after they’ve re-installed their Windows version and tried to open a .reg file. Based on the reports, this error could occur if the registry file does not have administrative privileges. Meaning to say, the program does not have the necessary permission to merge the .reg file. This is common with fresh installs as well as reinstalls. Moreover, this kind of issue could also occur due to system file corruption. Whichever the case may be, here are some troubleshooting tips you can check out to resolve the error.

Option 1 – Try to import the .reg file with admin privileges

As pointed out, the error may be due to a lack of admin privileges. It could be that the Registry Editor does not have admin privileges to merge the registry file. This is common with new Windows installations especially since the Registry Editor hasn’t been opened before. So you need to import the .reg file again and this time, with admin privileges.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and tap the Ctrl + Shift + Enter keys to open the Registry Editor with admin privileges.
• A User Account Control or UAC prompt will appear where you have to click Yes to proceed.
• After opening the Registry Editor, go to File > Import using the ribbon bar at the top.
• Next, use the import menu to go to the location of the file you were trying to merge. Once you’ve found it, click Open to merge it with your current registry. This should fix the problem. If not, refer to the next options below.

Option 2 – Try performing a System Restore

Running System Restore can also help you fix the error when accessing the Registry. 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.
• Once the next startup is complete, you have to merge or import the file again and see if the error is now fixed or not.

Option 3 – Try to perform repair install by creating a Windows 10 installation media

• Click this link and then click the Download Tool Now button.
• Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
• Now select the ISO file option in step 5.
• After that, you should now have an ISO file.
• Next, go to the location where you’ve downloaded the ISO file.
• Then right-click on the Windows 10 ISO file and select the Open with option and then select File Explorer.
• Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

Option 4 – Try running the System File Checker Scan

As mentioned, the error when accessing the Registry might be caused by file corruption. And that’s where the SFC scan comes in. The SFC or System File Checker scan could detect and automatically repair damaged system files. 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 with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.

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.

• Now restart your computer.

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, from the list of services, look for the following services in the given order:

• After you find the aforementioned services, make sure to check if they are enabled or not and then restart each one of them.
• Once done, try to open the Windows Sandbox again and see if the error is fixed or not.
