Download "NSSM" from here:
https://nssm.cc/release/nssm-2.24.zip
Unzip the “nssm” folder in the directory:
C:\Users\ashish\Desktop\Workspace\Jupyter\(Installations)
Add the following path to the “PATH” variable:
C:\Users\ashish\Desktop\Workspace\Jupyter\(Installations)\nssm-2.24\win64
To create a service:
C:\windows\system32>nssm install Del_temp_files
Service
"Del_temp_files" installed successfully!
Python scripts do get installed but they do not run:
C:\windows\system32>nssm install Py_log_timeService "Py_log_time" installed successfully!
|
import
time
while
True:
with
open('C:/Users/ashish/Desktop/Log.log',
'a')
as
f:
time.sleep(3)
f.write(str(time.time()) + "\n")
|
Even if you try to launch it using a BAT file:
Contents of “Script.bat”:
|
python C:\Users\ashish\Desktop\Script.py
|
To create a Python based service using NSSM (Note: the
Python program above did not work with this method):

URL:
https://stackoverflow.com/questions/32404/how-do-you-run-a-python-script-as-a-service-in-windows
The simplest way is to use the: NSSM - the
Non-Sucking
Service Manager:
1: Make download on
https://nssm.cc/download
2: Install the python program as a service: Win
prompt
as admin.
C:\>nssm install My_Win_Service
3: On NSSM´s console:
Path:
C:\Users\ashish\AppData\Local\Continuum\anaconda3\python.exe
Startup directory:
C:\Users\ashish\AppData\Local\Continuum\anaconda3
Arguments:
C:\Users\ashish\Desktop\Script.py
You can find out the value for “Path” using
command
“where python” in the Windows CMD.
4: Check the created services on
“services.msc”
|
To remove a service:
C:\windows\system32>nssm remove Del_temp_files
Service
"Del_temp_files" removed successfully!
The above command disables the service but does not
delete it.
To delete a service that has not been automatically
removed by a software uninstall you need to edit the registry:
1.
Start the registry editor
(regedit.exe)
2.
Move to the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services key
3.
Select the key of the service you
want to delete.
4.
From the Edit menu select
"Delete"
5.
You will be prompted "Are you sure
you want
to delete this Key" click ‘Yes’
6.
Exit the registry editor.
Another attempt to create a Windows service using
‘pyinstaller’:
If you are using conda (and not ‘pip’) then you will have
to use the following commands instead:
conda install -c conda-forge pyinstaller
conda install -c anaconda pywin32
To create an “exe” for your Python program:
(base)
C:\Users\ashish\Desktop>pyinstaller --onefile
Script.py
39041 INFO: Appending
archive to EXE C:\Users\ashish\Desktop\dist\Script.exe
39057 INFO:
Building EXE from EXE-00.toc completed successfully.
Now, create a Windows service as follows:
1: Install the python program as a service: Win prompt as
admin.
C:\>nssm install My_Win_Service_2
2: On NSSM´s console:
Path: C:\Users\ashish\Desktop\dist\Script.exe
