FileBeat as a service. After rebooting the system it starts automatically

hi @TUSHAR_Sinha, sorry for the late reply, in the install file the service's startup type should be automatic (delayed) so it should restart each time.
I was interested above in the startup type of the service, can you run
GET-Service filebeat | select -property name,starttype
and let me know what is the result?
I wonder if tries starting but it's being stopped, can you check the logs and let us know if you see anything suspicious (was filebeat starting but had to stop?, any exceptions)?
Also, I mentioned the msi above, did you give that one a try instead, it would be interesting to see if the behavior changed if it has been installed through the msi.
