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?
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.
