Symptom:
Large amount of space used by the Windows Temp directory.
Specifically it seems a log file under `C:\windows\Logs\CBS` becomes corrupt, after which small but numerous `cab_xxxx` files start to appear in the `C:\windows\temp` directory.
Incident Resolution:
The incident is easily fixed:
- Delete the largest/oldest log file from `C:\windows\Logs\CBS`
- Delete all `cab_xxxx` files from the `C:\windows\temp`
(some posts suggest stopping & starting the windows update service / regenerating the cab files after performing the above).
Problem Prevention:
NB: It seems that the root cause is known: makecab.exe
utility
cannot handle files over 2GB.
Question: Is there a hotfix to correct this bug? If not, is there anything in the pipeline?
