cab_xxxx files found in WINDOWS\TEMP folder

Does anyone know what program can create files in the Windows\Temp folder that begin with cab_xxxx (four digits typically)? these files are building up; one of every four is 41MB in size; the rest are usually 0 bytes. Any ideas?

Hello,

we had the same problem. Deleting the cab_xxxx files only resulted in regeneration every 30min.

Checking <windows>\Logs\CBS folder I found lots of .log and (some) .cab files

It seems, that windows wasn't able to zip (makecab.exe) one of the .log files.

Solution was:

in <windows>\Logs\CBS folder delete the oldest .log file (you can also delete them all)

in <windows>\temp folder delete every cab_xxxx

in the following regeneration process, the remaining (CBS) logs where zipped correctly, and <windows>\temp was left clean

Hi,

 

The CAB-xxxx files that you see in the C:\Windows\Temp\ folder are some temporary files created by different Windows Operations, like installing Updates. You can safely delete these files off from that folder. Alternatively, you can also run Disc Cleanup to delete the temporary files from your computer.

 

I would suggest you to try the Methods mentioned below and check if it helps:
