Windows 7 SP1 doing unexpected language pack operations, filling up CBS log

Posted on 2015-01-19
Last Modified: 2015-01-27

I have an Asus Windows 7 SP1 Laptop.

I have noticed that the CBS log grows by about 20Gb a week, quickly filling the hard drive.

On closer inspection the CBS persist file timestamps match with log entires such as the one at the bottom of this post.

The log contains a lot of similar entries, with many different language pack codes.

The computer has no need of langauge packs other than UK English, so I have no idea what is triggering these events. Additionally, lpksetup only shows UK English as installed!

Did you install the Chinese language pack or are you trying to remove it?

I swear I participated in a thread with the exact same problem not too long ago, but I can't find it.

Anyway, the CBS.log file is part of the Windows Resource Protection.

Running System File checker may help:

The problem may be with Windows Update. You can run the System Update Readiness Tool, or CheckSUR

No, I have neither installed or tried to remove a language pack ever on this laptop!
