Fix error 0x80070015 on Windows 10


Before you begin, Restart the computer and try again and see if that helps. If not, then proceed with the respective fixes for Microsoft Store, Windows Update, or Windows Defender :

  • Windows Updates.

  • Run Windows Update Troubleshooter.

  • Microsoft Store.

  • Kill the processes related to PowerISO.

  • Reregister Microsoft Store apps

  • Reset the Microsoft Store.

  • Windows Defender.

1] Windows Updates

[i] Run Windows Update troubleshooter


Use the Windows Update Troubleshooter or Microsoft’s Online Windows Update Troubleshooter to detect and fix any conflicts for Windows Updates automatically.


[ii] Manually reset Windows Update files & folders


You need to delete the contents of the Software Distribution folder & reset the Coatroom folder to fix your issues. They contain some temporary system files that are responsible for applying updates to a computer. They include data that support Windows Updates as well as installers for new components.


You may also reset Windows Update components and the Windows Update Agent manually.


[i] Kill the processes related to PowerISO


  • Open the Windows Task Manager. Select More details.

  • Look for each process for the PowerISO software.

  • Right click on it and select End process tree.

[ii] Reregister Microsoft Store apps


  • Run the following command in an elevated PowerShell window to reregister Microsoft Store apps:

powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml
  • Restart your PC and check.

[iii] Reset the Microsoft Store

  • Reset the Microsoft Store by using the wsreset command. Make sure to execute this on PowerShell or Command Prompt as an Administrator. If not that, you could reset the Microsoft Store app from the Settings app.


3] Windows Defender


[i] Removal of any third party antivirus installed

  • You can try to uninstall AVG Antivirus or any other third party antivirus installed on your computer. This is because these installations of third-party antivirus can often interrupt the scanning process for Windows Defender. The most famous culprits, in this case, are the antiviruses by Norton and McAfee.
