Python Win32 Process

The Win32 process is essentially a Python procedure. This program provides access to advanced Win32 process creation and management features. Process objects are created through the Create method (the constructor). Further techniques may be used to stop, pause, restart, and set the prioritization of programs running on objects.

WMI plugins for the Windows Driver Model and Windows Management Intelligence (WMI; previously WBEM) are the basis for administration in Windows 2019/2016/2012/2008 and Windows 10/7/XP (WDM).

ActiveXperts Network Monitor gives users the option to develop WMI-based monitor test routines. ActiveXperts has accumulated more than a hundred WMI tests. You may use these cases as a springboard to develop brand-new check procedures with your own.

Your servers are monitored by ActiveXperts Network Interface using the Win32 Process WMI class.

The Win32 Process WMI class represents a sequence of actions on an operating system like Windows. A descendant of this class is a loop that result the interaction of one or more processing units some program files, and a set of items, including a user application running on a Windows computer.

The question of what Python win32 has now been emerges.

Therefore, by utilising PyWin32 library of modules for Windows, the Python win32 and Win32 API functionalities may be utilised with Python.

Win32api Package

The win32api package provides a number of additional ways for managing processes. These enable you to do the majority of the common actions required to start new procedures, but they fall short of providing the greatest amount of low-level control.

The WinExec function, in opposition to the os.system function that was described earlier, provides a number of GUI program-specific features. As an illustration, no console is created, as well as the function does not wait for the new procedure to finish.

Following two inputs are needed by the function:

  • The directive to act
  • Alternatively, the initial state of the application's window

Win32api ShellExecute

The win32api package also provides additional helpful capability for beginning new procedures. The major use of the ShellExecute function is opening files, not initiating arbitrary procedures. For example, you can tell ShellExecute to "open MyDocument.doc". To open.doc files, Windows decides which procedure to start on your side. An a.doc file may be opened in Windows Explorer by clicking (or double-clicking) on it.

The term "process" refers to an active programme. It's not necessary for a process to be one that the client initiates; alternatively, it may be a computer programme that the operating system launches. Any operating system software that want to execute must first create a distinct process in order to do so. In a conventional OS installation, background applications and operating system utilities are employed to maintain the functionality of the hardware, software, and operating system.

The win32process Module provides the best process control

One of most comprehensive procedure level control is offered by the win32process package, which makes the majority of the real Windows API for initiating, halting, controlling, and awaiting for different options available. But first, a few definitions are necessary until we dig into the win32process package.

Handles and IDs

A Windows address and an integer ID may be used to identify each task and operation in the system. An assigned process or thread ID is a special number that is valid throughout the whole system and is specific to that operation or task. An ID only helps to clearly define the thread or process while it is active and is unchangeable during that time. Since IDs are repeated, even though two threads or operations will never exchange an ID while they are active, the computer may utilize the same ID after a task or function has ended. IDs are also not safe. The ID for a thread or process can be acquired by any customer.

Since the ID is insufficient to manage the task or operation, this is not a safety concern.

A handle gives the thread or manage more controllable options. One can await for a program to end, force the closure of a process, or modify the properties of an active process by utilising a handle.

A process could have multiple handles if it is allowed to just have one ID. The freedoms a user has to conduct activities on a procedure or task are determined by the handle of the activity.

Using a unique Id as input, the win32api function. You may get a handle with OpenProcess(). The privacy parameters for both the process itself as well as the potential customer govern who is permitted to use this handle.

Creating Processes

CreateProcess() and CreateProcessAsUser() are two methods in the win32process package that may be used to launch new operations. The only difference between both procedures is that CreateProcessAsUser() takes an extra parameter specifying the client under whom the process must be generated.

CreateProcess() supports a vast number of parameters that provide the new mechanism with a great deal of flexibility:

  • The application to run
  • Alternative command-line options
  • The new process's safety properties, or None
  • Risk characteristics for the incoming process's original thread or None
  • A flag specifying whether handles will be passed down to the new process.
  • Flags indicate the creation of the new process.
  • No atmosphere for the present environment or a new situation for the new procedure
  • The new process's current repository
  • Specifications on where and how to display the new window

Provides a tuple with four members as a result:

  • A control for the new procedure
  • This a reference to the new process's main thread
  • A number designating the new procedure
  • A number designating the new process's primary thread

Terminating Processes

The win32process can be used to end a process. The method of terminating the process() is utilised. This method requires two inputs:

  • A handle for the process that has to be stopped
  • The termination code to use in conjunction with the procedure

If you first established the new mechanism, getting the handle to it is pretty simple; all you have to do is recall the win32process output. Call to CreateProcess().

But what if the user didn't design the procedure? The win32api.OpenProcess() method may be used to get a reference if you understand the process ID. How can you locate the process ID, though? Such inquiry doesn't have a simple solution. One technique of retrieving the process ID provided the process name is demonstrated in the document included with the Python for Windows Extensions. This event demonstrates how to acquire a procedure handle that may be terminated using the win32api.OpenProcess() method.

Controlling Processes

The priority and the affinity mask are two input parameters that can be changed after a procedure has started to run. The windows arrange the threads in the process according to the relevance of the process. The importance may be set using the win32process.SetPriorityClass() method.

A multiprocessor computer is the only one where the affinity mask of a process is important since it specifies which processor the process is functioning on.

To determine this behaviour, use the win32process.SetProcessAffinityMask() method.

Putting it all together

The CreateProcess API and process credentials are used in this segment through a straightforward example. This instance won't really accomplish anything very helpful in order to make the important concepts clear; rather, it is limited to the following features:

  • Makes two copies of Notepad, each with a precisely planned out window location.
  • Delays the end of these occurrences by 10 seconds.
  • Kills the examples if they haven't ended by then.

The win32process is shown via this capability. How to utilise the CreateProcess() method in win32process.

Module win32process

An interface to the win32 Process and Thread APIs


  • STARTUPINFO: A new STARTUPINFO object is created.
  • Beginthreadex: A new thread is created
  • CreateProcess: Establishes a new process and the main thread for it. The newly created process runs the designated executable file.
  • CreateProcessAsUser: Generates a new process with the provided user as its surroundings.
  • GetCurrentProcess: Obtains a fictitious handle for the active process.
  • GetProcessVersion: Reveals the system's main and minor version numbers that are needed to conduct a certain process.
  • GetCurrentProcessId: Reveals the caller process's unique process identification.
  • GetStartupInfo: Reveals the STARTUPINFO structure's entries, which were supplied whenever the caller process was established. 
  • SetProcessPriorityBoost: Allows or inhibits a process's dynamic scheduling modification.
  • GetThreadPriorityBoost: Decides whether a thread's dynamic scheduling modification is allowed.
