Write a Python Windows service

1. Installing Pywin32 and Pyinstaller

pip install pywin32pip install pyinstaller

2. Write a service Demo

Preparetohostsingle (MyService) ServiceManager. StartServiceCtrlDispatcher () Else:win32serviceutil. Handlecommandline (MyService)

3. Freezing the binary

pyinstaller -F MyService.py --hidden-import=win32timezone

4. Running the service

dist\MyService.exe installsc start MyService
