For many years I run a particular python script as a service on my Windows XP machine. I used Microsoft Resource Kit tool srvany to “host” my script as as service. Recently, I replaced my XP machine at workplace with new one, running Windows 7 x64. Unfortunately, Microsoft stopped developing this tool, I heard that it still works, even on Windows 7 x64, but nevertheless I consider srvany as being dead.
Fortunately, there is good alternative, NSSM – Non Sucking Service Manager, free replacement for srvany with a bonus – it’s build for both, 32-bit and 64-bit OS.
Download and simply unzip nssm archive, then open elevated command prompt and install the service with the command nssm install [], in my case:

cmd> nssm install PyLogDirWatch
