Fix: DLLRegisterserver failed with Error 0x80070715 on Windows 10

Some Windows 10 users are reporting that they end up seeing an error prompt with the error 0x80070715 when attempting to open the Windows Security utility or when attempting to perform a certain action involving DLLRegisterserver.

Windows 10 Error 0x80070715

After investigating this particular error code, it turns out that there are several different underlying circumstances that might trigger this problem on Windows 10. Here’s a list of potential culprits that might cause this issue on Windows 10:

  • Volume Shadow Copy is Disabled – If you’re encountering this issue while attempting to use DllRegisterServer commands from a CMD or Powershell terminal, chances are the error is triggered because the Volume Shadow Copy service is disabled. If this scenario is applicable, you should be able to fix the issue by enabling the Volume Shadow copy from the Services screen.
  • Corrupted Windows Security App – In case you only see this error when attempting to initiate a scan via Windows Security, chances are you’re dealing with some kind of corruption that is affecting the application.  In this case, you should initiate a reset via the GUI Windows Menu, via Powershell, or via an elevated Command Prompt.
  • Windows Update service is disabled – If the error only appears when Windows Security attempts to download a new virus signature, chances are the service that should handle the download (Windows Update) is not reachable. In this case, you should be able to fix the problem by opening the Service screen and modifying the status type of the service.
  • Outdated Windows 10 build – As it turns out, Windows Security might also trigger this error when you attempt to open it due to a missing security update that is now a mandatory Windows 10 build. If you have blocked pending updates from installing, the only viable fix is to install every pending update until you bring your Windows 10 build up to date.

Method 1: Enabling the Volume Shadow Copy

As it turns out, if you’re encountering this issue while attempting to use a DllRegisterServer command inside a terminal, chances are you’re dealing with this issue because the main Volume Shadow Copy service is disabled.

Keep in mind that when attempting to register a DLL file via a CMD or Powershell terminal, you NEED to have the Volume Shadow Copy service enabled on your computer in order for the operation to be successful.

If you’re unsure if this service is enabled or not, follow the instructions below for step by step instructions on using the Services screen to ensure that the Volume Shadow Copy is enabled:

  1. Press Windows key + R to open up a Run dialog box. Next, type ‘services.msc‘ inside the text box and press Enter to open up the Services screen. If you are prompted by the UAC (User Account Control), click Yes to grant admin access.
    Accessing the Services screen
  2. Once you’re inside the Services screen, scroll down through the list of active services and locate the entry associated with Volume Shadow Copy.
  3. When you see it, right-click on it and choose Start from the context menu that just appeared.
    Enabling the Volume Shadow Copy
  4. After the service has been enabled, repeat the action that was previously triggering the 0x80070715 and see if the problem is now fixed.

Method 2: Resetting the Windows Security App

If you’re encountering the 0x80070715 error code when attempting to open the Windows Security app or when attempting to perform a scan using it, chances are you’re dealing with some kind of corruption that is preventing the security app from opening normally.

Note: Windows Security is the newer built-in security entity on Windows 10 that incorporates antivirus, anti-phishing, anti-ransomware, and a firewall solution.

Most commonly, this error code occurs when certain files belonging to the security suites are tainted by corruption. Several affected users that were dealing with the same issue have confirmed that the issue was finally resolved after they have successfully reset the Windows Security app.

When it comes to doing this, you have 3 available options:

  • Resetting the Windows Security App via the Start Menu
  • Resetting the Windows Security App via PowerShell
  • Resetting the Windows Security App via Command Prompt

Feel free to follow the guide that is closest to your preferred approach to doing things under Windows 10:

A. Resetting the Windows Security App via the Startup Menu

  1. Press the Start button on your keyboard, then use the search function to search for ‘Windows Security’.
  2. From the list of results, right-click on Windows Security and choose App Settings from the context menu that just appeared.
    Accessing the Windows Security tab
  3. Once you’re inside the Properties screen of Windows Security, scroll down to the reset tab and click on the Reset button.
    Resetting the Windows Security app
  4. Hit Reset once again at the confirmation prompt, then restart your computer once the operation is complete and see if you are able to open the Windows Security app once the next startup is complete.

B. Resetting the Windows Security app via Powershell

  1. Press Windows Key + R to open up a Run dialog box. Next, type ‘powershell’ inside the text box and press Ctrl + Shift + Enter to open up up an elevated Powershell prompt with admin access.
    Opening a Powershell prompt
  2. At the UAC (User Account Control) prompt, click Yes to grant admin access.
  3. Inside the elevated Powershell prompt, type the following command and press Enter to successfully reset the Windows Security app:
    Get-AppxPackage *Microsoft.Windows.SecHealthUI* | Reset-AppxPackage
  4. Once the operation is finished, restart your computer and see if the error code is fixed once the next startup is complete.

C. Resetting the Windows Security App via Command Prompt

  1. Press Windows key + R to open up a Run dialog box. Next, type ‘cmd’ inside the text box and press Ctrl + Shift + Enter to open up an elevated Command Prompts.
    Opening an elevated Command Prompt
  2. If you are prompted by the UAC (User Account Control), click Yes to grant admin access.
  3. Inside the elevated Command Prompt, type the following command and press Enter to process it successfully:
    PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage *Microsoft.Windows.SecHealthUI*).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"
  4. Restart your computer and see if the issue is fixed once the next startup is complete.

In case the issue is still not resolved even after you’ve successfully refreshed the Windows Security component, move down to the next potential fix below.

Method 3: Enabling the Windows Update Service

If you’re encountering the 0x80070715 error while attempting to initiate a scan inside Windows Security (and you’ve already tried resetting it using the method above to no avail), it’s possible to face this error due to the main Windows Update service not being enabled so new security signatures cannot be downloaded.

Several affected users that were previously encountering the same kind of issue have reported that the issue was finally resolved after they used the Services screen to force-start the Windows Update service and modify the Startup type before initiating the Windows Security scan once again.

To ensure that the Windows Update service is Enabled from the Service tab, follow the instructions below:

  1. Press Windows key + R to open up a Run dialog box. Inside the text box, type ‘service.msc’ and press Enter to open up the Services screen.
    Opening the Services screen
  2. Once you’re inside the Services screen, scroll down through the list of available services and locate the entry associated with Windows Update.
  3. After you manage to locate the correct entry, right-click on the Windows Update service and choose Properties from the context menu.
    Accessing the Properties screen
  4. Once you’re inside the Properties screen, access the General tab and modify the Startup type to Automatic before clicking on Start to force start the Windows Update service.
    Starting the Windows Update Service
  5. Once the Windows Update service is enabled again, initiate the same Windows Update scan that was previously failing with the 0x80070715 and see if the problem is now resolved.

Method 4: Install every Pending Windows Update

If you are using Windows 10 and you are encountering the 0x80070715 error when attempting to open Windows Security, it’s important to ensure that you have all the pending updates installed to ensure that you have every security dependency required installed.

Several users that were also encountering the 0x80070715 error when attempting to open the Security utility (or initiate a scan with it) have reported that the installation was finally successful after they took the time to install every pending Window 10 update from the Windows Update screen.

If you think this scenario looks like it could be applicable and you are not running in the latest version of Window 10, follow the on-screen prompts to install every pending Windows 10 update on your computer:

  1. Press Windows key + R keys to open up a Run dialog box. Once you’re inside the Run prompt, type ”ms-settings:windowsupdate’ and press Enter to open up the Windows Update tab of the Settings app.
    Opening the Windows Update screen
  2. Once you’re inside the Windows update screen, click on the Check for updates button on the right-hand side section.
  3. At the next prompts, follow the next instructions to install every Windows Update that is currently scheduled to be installed.
    Checking for New Windows Updates

    Note: It’s important to install every type of update including cumulative and security updates, not just the ones labeled as Critical or Important.

  4. In case you are prompted to restart your computer before every update is installed do so, but make sure to return to this screen at the next startup and finish the installation of the rest of the updates.
  5. After every pending update is successfully installed, reboot your computer again and repeat the action that was previously failing with the 0x80070715 error code.
