The Steam Client Bootstrapper application should not consume much CPU resources on your computer. It is a background application that can be used to download and install updates or replace missing files. You can expect a higher CPU load when downloading or installing updates.

However users report that this process consumes CPU resources even when Steam is idle. In some cases, this happens even after a complete steam shutdown. There are several ways to solve this problem. Therefore we suggest you check them step by step below.

Reboot the PC

Windows 10 stuck on restart

PC reboot will solve 80% of problems. You may have a lot of applications running and the Steam Client Bootstrapper is not getting the bandwidth it needs to work properly. When you reboot your computer, the system will update and the Steam client loader will get enough bandwidth. To solve this problem, restart your system. Check if this solves the problem.

Reconnect the Internet

Disconnect and reconnect the Internet. When using bandwidth in the background, some adverse factors may appear. Thus, when you disconnect from the Internet, these factors are also disconnected. Now connect to the Internet again to renew your connection.

Disconnect the antivirus program

When you run the Steam application, it may not open because the antivirus is interrupted. Make sure; you do not use any third-party antivirus programs. If there is a third-party antivirus on your system, turn it off and restart the system. Now you can start Steam without displaying an error.
