For example, it appears when a specific library cannot be found or when one of the modules of a certain program is not loaded.

If this error has appeared on several occasions and you have no idea how to solve it, keep reading this post to show you what you should do to correct the error 0x80070015 in Windows Update, Store, or Defender.

What to do to fix error 0x80070015?

Next, we will talk about everything you need to do to correct the windows 10 error code 0x80070015 in Windows Update, Defender, and Store. Depending on where the error appears, we will have to follow a completely different series of steps to solve it.

However, it is not such a difficult task since we have taken the task of explaining it in the simplest way possible. Let's get to it!

Windows update

If this error appears when you are trying to download the latest update from the Windows Update agent, this means that some of its services are having problems running properly.

To solve this error, you have to open the Windows Update troubleshooter, which will do a deep analysis of the application and then show us both the errors and the possible solutions.

Generally, we will not have to download anything additional since this tool applies the corrections that the program needs to function normally.

On the other hand, you can try deleting a folder called "SoftwareDistribution." This is also a useful alternative if the Windows Update troubleshooter cannot find the error for this app.

Windows Store

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

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. If you have not installed this app before on your computer, then the error may be caused by other Microsoft apps having a registry problem.

To solve this, you must 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 store to ensure everything works fine.

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

Windows Defender

When this error appears in Windows Defender, it is a sign that a failure occurs in some of its modules when activating the Windows Defender antivirus. Therefore, it cannot function correctly.

One of the most common causes of this error is that the user recently decided to install a free antivirus on the computer or that could not completely uninstall it. There are still some databases of this third-party app.

Regarding the solution, first, you have to make sure that there is no antivirus on your computer (NOD32, Avast, AVG, Kaspersky, among others). In case you have any of these antivirus installed on your computer, then proceed to uninstall them correctly and then restart the computer. After doing all this, Windows Defender should work correctly.
