Steam Client Service from Valve. It is the elevated install and update helper. steam.exe is the Steam client you click.

What you need to know

SteamService is the elevated service, not steam.exe.

SteamService.exe is the Steam Client Service. Valve uses it so Steam can install and update content without prompting every time. steam.exe is the store and library. Ending the service does not quit the client window.

Safe?: Yes, from Valve Steam
Is it the client?: No. steam.exe is the client
Need it?: Installs and updates in protected folders

Feex says

If Steam says Steam Service Error, I repair SteamService. I do not delete steam.exe to "remove the service."

What is SteamService.exe?

SteamService.exe is the elevated Steam Client Service, not steam.exe. The service binary often lives under Common Files\Steam. The client you launch is Program Files (x86)\Steam\steam.exe.

What does it do?

It performs privileged install and update work so the client does not stay elevated. It does not draw the store. steamwebhelper.exe is the embedded web helper, not this service.

Why is it running?

Steam is installed. The service can sit idle until an install, a redistributable, or a privileged update needs it. A "Steam Service Error" dialog means this helper, not a missing game exe.

Is it safe?

Usually safe when Valve signed

A Valve-signed SteamService under Common Files\Steam or Steam\bin is the service. A SteamService.exe in Temp is not. This is still not steam.exe.

A legitimate copy normally runs from:

C:\Program Files (x86)\Common Files\Steam\SteamService.exe

Repair copy also exists as Steam\bin\SteamService.exe
Service name: Steam Client Service
Client UI is steam.exe

Can I end it?

Privileged Steam installs can fail

Ending SteamService.exe does not quit steam.exe. The next install into Program Files can fail until the service starts again.

Can I remove it?

Uninstall Steam, do not delete the service exe

Use Steam's uninstall. Deleting SteamService.exe leaves a broken client. Ending steam.exe does not uninstall the service.

Should it start with Windows?

Windows can start Steam Client Service as a service. steam.exe still has its own "run at startup" checkbox.

Normal resource behavior

These are contextual labels, not universal averages.

CPU: Short spike during a privileged install
Memory: Small when idle
Disk: Follows the Steam content write
Network: None by itself. steam.exe downloads

Common problems

Steam Service Error on launch

The client cannot talk to this service. Repair it. Closing steam.exe only dismisses the window.

People disable the service to "save RAM"

The idle service is small. The cost shows up later as failed installs into protected folders.

Troubleshooting

Diagnose before you change anything destructive.

Repair from an elevated Command Prompt

Valve's helper accepts Steam\bin\SteamService.exe /repair. Point it at your Steam folder if it is not the default path. That is not a steam.exe switch.

Check services.msc for Steam Client Service

Start the service if it is stopped. Do not set steam.exe to Automatic in Services. steam.exe is not a service.
