I believed that a service running - like any other process - locks its executable file (as in use).

In fact I need to stop the service when I build a new version of it in Visual Studio and then I start it again.

I don't understand how they updated the executable without stopping the service (during a deploy) and then - afterwards - they just restarted the service for the changes to take effect.

Anyone has an explanation to this?

  • Use SC command. Stop service: sc stop service_name then change executable: sc create service_name binPath= abc.exe then start the service sc start service_name – Biswapriyo Sep 1 '17 at 9:26

Actually the file cannot be deleted (or similarly you can't overwrite the very same file), but can be renamed or moved.

So, in this way, it can be replaced.
