What is dbus-daemon.exe?

The genuine dbus-daemon.exe file is a software component of D-Bus by Red Hat.
Dbus-daemon.exe is an executable file that is part of D-Bus, a communication framework between multiple applications. This is not a critical Windows component and should be removed if known to cause problems. D-Bus makes it possible to launch multiple applications and daemons by coding a "single instance" application. D-Bus is built on the libdbus library which multiple applications can connect to. The D-Bus protocol finds implementations in languages like C#, Java, and Ruby. D-Bus is being replaced at the moment with kdbus which seeks to improve overall performance. Red Hat is an American company that is best known for developing open-source software, most notably Red Hat Enterprise Linux. Since 2013, Red Hat has been the largest contributor to the development of Linux. Red Hat was founded by Marc Ewing in October 1994. Bob Young of the ACC Corporation later bought Ewing's company but the two later merged to form Red Hat Software. Red Hat is headquartered in Raleigh, North Carolina, USA.
