SilentRun

SilentRun is a small and handy system software utility for Windows that allows you to easily run multiple programs silently in the background. It can hide windows and program interfaces and increase or decrease the priority of background processes. For some programs with sound output, SilentRun can also mute them and then run them silently in the background.

In addition to the visual GUI interface, SilentRun also provides a command line mode that allows you to run other visual programs via the command line. It automatically hides the interface of these programs and places them in the background to run silently. Command line mode also supports providing parameters to invoked programs and EXEs.

In addition, it has a portable ZIP version and several language packs.
