How to Fix Corrupted CBS.log in Windows 11

Component-Based Servicing, or CBS, is the name of a file that keeps track of the Windows Update components that have been installed and removed.

The System File Checker (SFC) also writes to the CBS.log file, which is where information about your Windows Update is saved.

The CBS.log file keeps track of changes made when an update is installed and when the SFC scan is run. It helps when figuring out what’s wrong with the computer and how to fix it.

This article will guide you on how to fix corrupted CBS.log.
