Thread Status allows you to inspect information about each running thread in an application.
Processes
Processes are shown in the top grid. The process id and the process name are shown. You can sort the grid by clicking the appropriate column header.
By default only user processes are shown.
System processes (executables in the Windows systems directory) and services can be shown if you want to monitor one of those.
Use the three check boxes to control which types of process are shown.
Threads
Threads are shown in the bottom grid. The thread id, thread name and thread statistics are shown. You can sort the grid by clicking the appropriate column header.
Information that is displayed about each thread:
Thread id
This is the numeric identifer assigned to the thread by the Windows operating system.
Name
This is the name of the thread if the thread has been given a name using the SetThreadDescription() API. This is only available on Windows 10.
If a thread description is not available we attempt to provide a name for this thread by querying the thread's start address, and if successful we try to turn this start address into a useful symbolic name. Depending on the process and the operating system these operations may success, in which we display a name, or they may fail in which case we display nothing.
