How to Fix Steam Client Bootstrapper High CPU Usage

Fix Steam Client Bootstrapper High CPU Usage

The Steam Client Bootstrapper is a background application for downloading and installing updates and replacing missing files. The problem with this app is that it may cause high CPU usage when it's not downloading anything. This article will explain the causes of this behavior and provide you with several ways to fix it.

Steam Client Bootstrapper High CPU Usage

Under normal circumstances, when Steam Client Bootstrapper performs its dedicated tasks, it uses some CPU resources, but not much. However, the issue with Steam Client Bootstrapper is that it uses a lot of CPU resources when Steam is idle. It's also common for it to use many CPU resources even when Steam is completely closed.

What Causes Client Bootstrapper High CPU Usage?

  • Red Shell spyware used to be installed alongside Steam games, but this issue has since been resolved. However, it's possible that Red Shell spyware is still on your PC and continues gathering data and causing high CPU usage.
  • The Steam Overlay may also cause Steam Client Bootstrapper to use more CPU resources than normal. The Steam Overlay causes many games to become unstable. Moreover, the Steam client often has a hard time on account of the overlay, so it's a good idea to disable it.
  • Steam allows users to set custom skins for your Steam client, but changing to a custom skin may cause Steam Client Bootstrapper to use a lot of your CPU's processing power. Therefore, it's recommended to revert back to the default Steam skin.
  • You may experience Steam Client Bootstrapper high CPU usage if you've set your Steam homepage to the Store. Setting the homepage back to Library often fixes the high CPU usage problem.
