File extension pythonw.exe is part of the software for Python programming language. The file provides users with a process known as ActiveState ActivePython. What the file does is to enable users to create scripts without having to go to the Windows console, or what is more commonly known as the DOS prompt window. The file launches a Graphical User Interface that allows programmers to work around the usual issues encountered when creating Python scripts in Windows console, i.e. being directed to DOS prompt when Python is launched, instead of being allowed to write scripts in normal Windows interface. The file pythonw.exe allows users to work on their scripts outside of Windows console. The file automatically creates programs using the file extension, .pyw so the program can execute directly from Windows Explorer, instead of having to once again use the DOS window, as is the normal way for programs with a .py extension. The file is located in the Program Files folder.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. pythonw.exe. is used by ActiveState ActivePython, If you shut down pythonw.exe, it will likely start again at a later time either after you restart your computer or after an application start. To stop pythonw.exe, permanently you need to uninstall the application that runs this process which in this case is ActiveState ActivePython, from your system.

After uninstalling applications it is a good idea to scan you Windows registry for any left over traces of applications. Registry Reviver by ReviverSoft is a great tool for doing this.

A process usually a part of an installed application such as ActiveState ActivePython, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.
