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!
