If Windows\Temp fills up with CAB files

See
http://www.infoworld.com/article/3112358/microsoft-windows/windows-7-log-file-compression-bug-can-fill-up-your-hard-drive.html

It has to do with CBS log files passing 2GB and a compression bug running amuck.

Stop:
  Windows Modules Installer service

Move/Ren/Del files in
   C:\Windows\Logs\CBS

Restart
