/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.








If you want to confirm that, launch one or all of your WinBoat apps. While they are running, run
pidof windows. If that gave some pids, runpstree -sp <pid>. That command shows the parent processes, with their pids, of the<pid>. WinBoat probably should be among the parents of the “windows” process.
