Hi,
It's part of rempl v2 (forced update hijackers) installed by KB4023057 and KB4295110 to force update any version of Windows 10 to 1803.
KB4023057 and KB4295110
create "Service name: sedsvc" "Display name: Windows Remediation Service" which runs "%ProgramFiles%\rempl\sedsvc.exe"
creates "\Microsoft\Windows\rempl\shell" task and runs "%ProgramFiles%\rempl\sedlauncher.exe" (which has replaced "%ProgramFiles%\rempl\rempl.exe") every 23 hours.
So, delete the %ProgramFiles%\rempl folder or use a script to disable it. One such script is the WUMT Wrapper Script. The latest version is always on Major Geeks.
