tldr Python 3.5 Windows Service build with pyinstaller : gist

Here a simple Windows Service with python :

WindowsService.py

import servicemanager
import socket
import sys
import win32event
import win32service
import win32serviceutil


class TestService(win32serviceutil.ServiceFramework):
    _svc_name_ = "TestService"
    _svc_display_name_ = "Test Service"

    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
        socket.setdefaulttimeout(60)

    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        win32event.SetEvent(self.hWaitStop)

    def SvcDoRun(self):
        rc = None
        while rc != win32event.WAIT_OBJECT_0:
            with open('C:\\TestService.log', 'a') as f:
                f.write('test service running...\n')
            rc = win32event.WaitForSingleObject(self.hWaitStop, 5000)


if __name__ == '__main__':
    if len(sys.argv) == 1:
        servicemanager.Initialize()
        servicemanager.PrepareToHostSingle(TestService)
        servicemanager.StartServiceCtrlDispatcher()
    else:
        win32serviceutil.HandleCommandLine(TestService)

Create an exe with pyinstaller (pip install pyinstaller) and python 3.5 :

(env)$ python -V
Python 3.5.2

(env)$ pip freeze
PyInstaller==3.2

(env)$ pyinstaller -F --hidden-import=win32timezone WindowsService.py

Install and run the service

(env) dist\WindowsService.exe install
Installing service TestService
Service installed

(env) dist\WindowsService.exe start
Starting service TestService

Check C:\\TestService.log file.

Stop and clean

(env) dist\WindowsService.exe stop
(env) dist\WindowsService.exe remove
