DLLRegisterserver failed with error code 0x80070715″ usually occurs when users try to access Windows Security or System Restore, among other tasks on Windows 10. This indicates that the “DLL” file is either corrupt or completely missing. There are several other reasons for this error, depending on the program or function that is causing it.

The details of the error may seem a bit complicated, but the solutions are very simple and easy to implement. Follow the fixes mentioned in the article in the order given until the error is fixed.

What causes the error 0x80070715?

Damaged Windows Security application: If you only see this error when trying to run a scan through Windows Security, you may be dealing with some kind of corruption that affects the application. If this is the case, you should run a reset via the Windows GUI menu, Powershell, or the extended command line.

Volume Shadow Copy is disabled: If this problem occurs when you try to use the DllRegisterServer commands from the CMD terminal or Powershell, the error may be due to the Volume Shadow Copy service being disabled. If this script applies, you may be able to resolve the problem by enabling Volume Shadow Copy on the Services screen.

Outdated Windows 10: It has been found that Windows Security can also cause this error if you try to open it because of a missing security update, which is now a mandatory Windows 10 build. If you have blocked the installation of pending updates, the only acceptable solution is to install all pending updates until you update your Windows 10 build.

Windows Update service not working: If the error occurs only when Windows Security tries to download a new virus signature, the service that is supposed to perform the download (Windows Update) is probably not working. In this case, you can solve the problem by opening the service screen and changing the service status type.

When regsvr32 registers a DLL file, information about related program files is added to the Windows registry. Other programs can refer to these registry references to understand where these programs are located and how to interact with them.

A DLL is a library that contains code and data that can be used by several programs at the same time. For example, in Windows operating systems, the DLL Comdlg32 performs common dialog box functions. Each module can be loaded into the main program at runtime if that module is installed.
