If you are having trouble downloading an update, a game or an add-on, this guide will help you repair the Steam client. The easiest way to repair Steam is to reinstall it. However, we don't want to spend hours redownloading all our games, so our first step is to back up our game installation. Now, simply reinstalling the Steam client should take a matter of minutes.

Step 1 - Backup Game Installations

  1. Fully Exit Steam and ensure it is not running by checking Task Manager.
