Issue: How to fix "BITS service failed to start. Error 0x80004015" in Windows?

Hello. I can't manage to install any Windows updates because the system is giving me the “BITS service failed to start. Error 0x80004015”. Is there a solution to this?

Solved Answer

The “BITS service failed to start. Error 0x80004015” is an issue that can occur on Windows operating systems, affecting the Background Intelligent Transfer Service (BITS). BITS is a critical component of the Windows operating system that allows for asynchronous, prioritized, and throttled file transfers between clients and servers. It is particularly useful for background processes such as downloading Windows updates, software installations, and file transfers without severely reducing system performance.

The BITS service works by dividing huge files into smaller segments, allowing it to download files more efficiently and effectively. This is especially beneficial when downloading data over untrustworthy connections or when users want to prevent overburdening network bandwidth. However, difficulties such as the “BITS service failed to start” error can obstruct the proper operation of this service, affecting different parts of the user experience.

The disruption in Windows Update operations is one of the most noticeable consequences of the BITS service failing to start. Because the BITS service is so important in obtaining and installing updates, a faulty BITS service can result in failed updates. As a result, the system may be open to security attacks and may lack critical improvements to existing functionalities.

There are various potential solutions to the “BITS service failed to start. Error 0x80004015”. To begin, restarting the BITS service may help to resolve any temporary issues. It is recommended to test network connectivity because network issues can affect BITS operation. A System File Checker (SFC) scan can also discover and fix any corrupted system files that may be causing the problem. Another precaution is to run a virus scan, as unwanted software can affect different system components, including BITS. Finally, users can use the built-in Windows Troubleshooter, which is designed to automatically diagnose and cure a wide range of system issues, including BITS issues.
