Hello,we had the same problem. Deleting the cab_xxxx files only resulted in regeneration every 30min.Checking LogsCBS folder I found lots of .log and (some) .cab filesIt seems, that windows wasn't able to zip (makecab.exe) one of the .log files.Solution was:in LogsCBS folder delete the oldest .log file (you can also delete them all)in temp folder delete every cab_xxxxin the following regeneration process, the remaining (CBS) logs where zipped correctly, and temp was left clean
