What to do to fix error 0x80070015?

Next, in this new post we will talk about everything you need to do in order to fix error 0x80070015 in Windows Update, Defender and Store. Depending on where the error appears, we will have to follow a completely different set of steps to fix it.

However, it is not such a difficult task, as here we have taken it upon ourselves to explain it in the simplest way possible.

Windows update

If you get this error when trying to download the latest updating from the Windows Update Agent, it means that some of its services are malfunctioning.

Now, to fix this error, you have to open the Windows Update troubleshooter, which will perform a thorough analysis of the application and then show us both errors and possible solutions.

Typically, we won't have to download anything additional, as this tool applies the fixes the program needs to function normally.

On the other hand, you can try to delete a folder called “SoftwareDistribution”. Which is also a useful alternative in case the Windows Update Troubleshooter cannot find the error for this application.

Windows Store

Now it is also common for this error message to appear in the Windows app store. There is no single reason why this error occurs, as it could be due to incompatible software or simply because there are errors in the applications we are trying to download.

So, first of all you have to uninstall the PowerISO app, as it is one of the main causes of this error message appearing on the screen. However, if you haven't installed this app on your computer before, the error may be caused by other Microsoft apps that have a problem in the registry.

To fix this, you have to open the console window or "power shell" with administrator permissions and enter the command line that we will show you below: "powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $ Env: SystemRootWinStoreAppxManifest.xml"

Next you have to restart your computer, wait a few minutes and then go back to the Windows archive to make sure everything is working correctly.

If that doesn't work, you need to go back to the window “Power Shell” to restore the initial settings with the “wreset” command. With this last method the error message in the Windows store should disappear permanently.

Windows Defender

When this error appare in Windows Defender, it is a sign that while activating the Windows Defender antivirus, an error occurs in some of its modules and therefore cannot function properly.

One of the common causes of this error is that the user recently decided to install a free antivirus on their computer or failed to uninstall it completely and there are still some databases of this third party app.

As for the solution, first you need to make sure that there is no antivirus on your computer (NOD32, Avast, AVG, Kaspersky, among others). In case one of these antivirus is installed on your computer, proceed to the correct uninstallation and then restart your computer. After doing all this, Windows Defender should work fine.

Now, if you've had an antivirus for a while but uninstalled it at the time. What you need to do is to install it again and then safely remove it. The idea is that the traces of this antivirus that are generating the Windows Defender error message are completely erased.
