Any way to stop "Epic games Unreal launcher " to be launched on editor's start up?

Each time I lunch unreal editor it auto starts "Epic games Unreal launcher " .
this is annoying to me.
Is there any way to stop that?

solved.
i have removed “\Engine\Extras\UnrealEngineLauncher”.
and then renamed “EpicGamesLauncher.exe” to something else.
that is it.
some other alternatives can be found:

At this point in time most people already know that Epic has no intention of adding this feature and rejected the pull request that implemented this as a configuration setting in the editor. I believe this is a useful addition to the editor so I went ahead and refactored pull 1427 and attached the diff so that one can apply it to the 4.19-release branch.

This requires that one obtain the Unreal Engine source code from Github, apply the attached patch, and compile.

It is important to note that the launcher will NOT start up by default anymore, but this behavior can be enabled under the Editor Preferences under General->Loading and Saving->Startup if desired.

May it be useful to someone down the road.

  1. Create an empty “PerforceBuild.txt” file.
  2. Copy it into “C:\Program Files\Epic Games\UE_4.19\Engine\Build”.

It works, but also has the side effect of disabling the In-Editor Compile button.

I’d be happy if in-editor compile stopped to work, unfortunately for me this workaround didn’t helped at all. :frowning:
