Issue: How to fix Windows Update Troubleshooter error 0x803c0103?

Hello. I couldn't update Windows since a few days ago. I decided to run an update troubleshooter, but I received an error 0x803c0103, so now I'm stuck. Is there anything else I can do to update my PC properly? I'm using Windows 10.

Solved Answer

Many users have reported receiving the 0x803c0103 error while using the Windows update troubleshooter. In this article, we explore the reasons why it's happening and how to fix it, finally allowing you to update your PC.

Windows updates are crucial for any system's security and stability, and applying them can also improve user experience thanks to new features, bug[1] fixes, and other improvements. Unfortunately, users who do want to keep their systems in the best condition can sometimes be stopped by the update process not working properly.

While Microsoft servers can indeed go down for a short period of time (which would prevent people from downloading the appropriate files), they usually come back up very quickly. The main issue due to which users are unable to update their systems are various errors, e.g., 0x8007371c, 0x800f0984, or 0x8024ce0e.

Many of such issues can be fixed with the help of the automated, built-in Windows component – a troubleshooter. Usually, this is the first method that people employ to tackle problems with Windows updates. The tool scans the system, finds the malfunctions within it, and either fixes them automatically or provides instructions on how to do that in case it can't be done automatically.
