I have implemented windows service:
class AppService(win32serviceutil.ServiceFramework):
and

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

in this service I call a function to take a screenshot, if I run this function not from the service its works but from the service I get this error:
ERROR: Error taking screenshot: screen grab failed
this is the function:

def share_screen(server_api, logger):
    # take screenshot and save to file
    try:
        logger.info("Taking screenshot")
        screenshot = ImageGrab.grab()
        screenshot.save(os.path.join(os.path.dirname(os.path.abspath(__file__)), 'screenshot.png'))
        logger.info("Screenshot saved")
    except Exception as e:
        logger.error("Error taking screenshot: %s", e)

I have understood that its could be failing because the service is not running on an interactive session, how can I make it run on interactive session or how could i resolve the problem in other way?

I have tried using the windows task scheduler but I couldnt schedule the task to run every 2 seconds from when i schedule it.
