NoSteamWebHelper

A program that disables Steam's CEF/Chromium Embedded Framework.

Aim

This program was created with the intent of replacing of Steam's command-line parameter -no-browser which was removed.

How does NoSteamWebHelper kill or disable the CEF/Chromium Embedded Framework?

The dynamic link library toggles the CEF depending if an is app running or not.

• If an app is running then the CEF is disabled.

• If an app is not running then the CEF is enabled.

This way, Steam is still accessible to use.

Usage

1. Download the latest release from GitHub Releases.

2. Place umpdc.dll in your Steam installation directory where steam.exe is located.

3. Make sure Steam is fully closed and launch a new instance of Steam.

4. Start up an app and the CEF will be toggled accordingly.

Note

• You may also manually toggle the CEF via a tray icon.
• To prevent the CEF from automatically showing when restored, pass -silent to Steam.
