High hard disk usage by SedLauncher

There are many reports from a large number of users complaining about the high use of the hard drive by ‘SedLauncher’ and ‘SedSvc.exe’. High disk usage can sometimes occur when the service/launcher downloads or installs an extensive feature update. The question may also arise if the service encounters a problem during the process. The only solution for high disk usage is to stop the service and process or wait for the high disk usage to disappear automatically.

Uninstall Service

Since the service is installed on the computer as an application, we will completely uninstall it in this step. For this:

  1. Press “Windows” + “I” to open the settings.
  2. Click on the “Apps” button and select “Apps & Features” in the left pane.
  3. Scroll down and click the “Windows Setup Remediation” or “Update for Windows 10” option.
  4. Note: One of these is available depending on the type of update.
  5. Click Uninstall and follow the instructions on the screen to completely remove it.

Disable the service

There are two ways to disable the sedlauncher.exe service on your PC. The easiest way is to open the Task Manager ” Right click on the sedlauncher.exe process and select the Finish task option. This way you can stop the process if it leads to an unnecessary use of the /pu hard disk at 100%.

Note that disabling the service is (no longer) sufficient to disable the dreaded Windows Remediation Service: At one point, Microsoft added a scheduled task that starts the “sedlauncher”. To disable it:

  1. Click Win + R and type “taskschd.msc”.
  2. Go to Task Scheduler (Local) > Task Scheduler Library > Microsoft > Windows > Fill
  3. Right-click on the Shell task and select Disable.
  4. To be sure, open the Task Manager, locate and exit the Sedlauncher.
