What is Sedlauncher.exe on my Windows 10 PC?

  • Rest assure you are not infected with any virus or malware.

After the KB4023057 update package, Microsoft has included Windows Remediation Service in Windows 10 OS. The Sedlauncher.exe is a part of this update.

This service is designed to improve the update speed and reliability of the Windows Update Service. This service helps you install the latest security patches and additional features so to keep your PC updated.

All Windows 10 build versions i.e. 1507, 1511, 1607, 1703, 1709, and 1803 have sedsvc.exe and rempl.exe files on them.

The SedLauncher.exe only starts consuming High CPU or Disk usage on Windows 10 when it downloads and installs large feature updates from Microsoft. During this process your PC may get slower but once it finishes you are good to go.

If this process keeps coming back you can temporarily remove or disable Sedlauncher.exe to prevent high disk usage on Windows 10. In both cases, you won’t automatically get the latest updates instead you have to resume Windows remediation service or manually download from Microsoft.
