Can I Delete CBS Log Files In Windows ? [RESOLVED]

The SFC.exe program record the information of each repair operation to the CBS.log file. The CBS.persist.log is a file generated when the CBS gets to be around 50 meg in size. CBS.log is copied to cbs.persist.log and a new cbs.log file is started.

This file is useful to troubleshoot some issues. If you’re not experiencing issues with the performance of your device, you may delete this file.

SFC.exe will create a new one, next time it is run. Here’s how:

1.    Disable/stop the trusted installer service (Windows Modules Installer) via windows services.

2.    Delete/move all of the current CBS log files from the \Windows\CBS\Logs directory.

3.    Restart the Windows Modules Installer service.
