How to fix Sedlauncher.exe high CPU usage on Windows 10

Find out how to Fix Sedlauncher.exe High CPU Usage Issue On Windows 10

Windows 10 is Microsoft’s best operating system to date. It’s very well optimized and runs smoothly on even old low-spec computers. Microsoft continuously updates Windows 10 to improve its performance and security. With the KB4023057 update package, Microsoft included Windows Remediation Service, which was designed to improve the update speed and reliability of the Windows Update Service.

Ironically, this update might do the opposite. Some Windows 10 users have attested that after installing the KB4023057 update, the PC’s CPU utilization shoots up to nearly 100%. Others have reported high Disk usage. Consequently, the whole system gets overloaded, so even non-resource intensive tasks take a long time.

How to fix sedlauncher.exe high cpu usage

The culprits for this unreasonable amount of CPU or Disk utilization are the “SedSvc.exe” service and the “SedLauncher.exe” launcher (stored in the “Rempl” folder in “Program Files”). Note that a file named rempl.exe also plays a role in this issue. All three files are part of the Windows Remediation Service, which is an update for specific Windows 10 build versions to handle the Windows update process smoothly.

The Windows Remediation Service is part of the KB4023057 Windows update package for 1507, 1511, 1607, 1703, 1709, and 1803 versions of Windows 10. It’s installed as an application and can be found in Apps and Features as “Update for Windows 10 for x64-based systems (KB4023057)” or “Windows Setup Remediations (x64) (KB4023057)”.

High CPU or Disk utilization can occur when SedLauncher.exe and SedSvc.exe are in the process of downloading or installing large feature updates. It can also happen if the service encounters a problem during this process. The solution to Windows Remediation Service’s high CPU or Disk utilization is to wait for it to finish installing updates or stop the process. You can also choose to remove the service from your system entirely.

Now, if you want to get the latest updates installed on your Windows 10 PC, you should keep Windows Remediation Service. However, if you don’t care about the updates, you can temporarily stop the service from running and resume it when you want or remove it from your PC altogether.

If you want to disable the Windows Remediation Service temporarily, we compiled three different guides on how to prevent the process from working that should accommodate your needs.
