I installed my windows service via (name of the service: Testing Service)
InstallUtil.exe present in .NET Framework (:\\Windows\\Microsoft.NET\\Fram
There is a Microsoft Visual Studio 2017 Installer available via Tools->Extensions and Updates
This official Microsoft Extension provides support for Visual Studio Installer Projects in VS2017
Installutil.exe (Installer Tool)
The Installer tool is a command-line utility that allows you to install and uninstall server resources by executing the installer components in specified assemblies.
Its job in life is to do exactly that,
To fill in your knowledge you should read through this
Chapter 2. Install/Uninstall
You will notice this is an entirely different concept, and actually has all the information you need (albeit in a very verbose manner)
There are various ways to achieve what you are after, one of them is using out of the box installation software, MSI, click once, or many others. or you could roll your own by using the above resources
InstallUtil only performs actions exposed by your .Net Installer classes, such as registering a service.
It does not perform the "standard" application installation which results in the entries being added into add/remove programs.
To do this, you will need to look at various install builders such as Wix, Installshield, etc.
InstallUtil.exe: As others have stated, InstallUtil.exe is intended for development use only, not for final distribution of your service.
MSI: The normal way to deploy services in the fashion you describe (with a proper entry in add/remove programs) would be to use an MSI installer created using a tool designed to help you do so (it is not advisable to "roll your own" tool to do this).
Ad-Hoc: The ad-hoc description of deployment tools below was written in a hurry, and has sort of been re-purposed as a general description of such tools. Not too relevant for the question asked, but it sort of "happened" and here it is.
How can I compare the content of two (or more) MSI files? (towards bottom) - (most of) these are not full-featured tools to make setups, but great to inspect MSI files and to create transforms.
There are many tools you can use for MSI-creation, for example (arbitrary order - links to Stefan Kruger's installsite.org below will show further tools, these are just the most common ones):
Free, open source framework - excellent, but with a learning curve, hence a few more links.
IsWiX - quick download
What are the above tools like in actual use? Here are some pragmatic observations and summaries:
There are many further tools available to create create installers / setup.exe files of various kinds (not just MSI tools, but general purpose, legacy tools, multi-platform tools, etc...):

Other Links:
Cross-Platform Installers: Does an universal cross-platform installer exists? (non-MSI tools).
dotNetInstaller: There is also the dotNetInstaller Setup Bootstrapper - which I have never used.
Some General Links: And there are various other ways to deploy - for example with self-extracting zip archives and stuff like that. Not recommended, but some links:
