From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

/proc/4212but its gone after I killed the process./proc is a special directory that is populated by procfs, a special kind of filesystem. It contains information about running processes. Each sub-directory contains information for one process. When you launch an application, it's assigned some process id. Every time you launch the application, it gets a different process id.
You can try and find the application by running
which windows. If the application is in your PATH, that tells where it is.Use
ps -efto find the source of the file.
