What is sedlauncher.exe and How to Fix High Disk Usage

When Windows released the update KB4023057 for Windows 10, the sedlauncher.exe process primarily served the function of improving the speed of the Window Update Service.  The executable is a part of the Windows Remediation Service and it is a digitally signed software of the Windows Operating System.
