Let’s get started on making your Windows 11 PC run smoother by controlling the sedlauncher.exe process.

Quick Note: What to Check Before Starting

• Check your Windows version: Make sure your system is up to date. Sometimes, outdated software causes unnecessary CPU usage.
• Restart your PC: A simple reboot can sometimes clear temporary glitches causing high CPU usage.
• Note the CPU usage: Open Task Manager (Ctrl + Shift + Esc) and confirm that sedlauncher.exe is indeed using a lot of CPU before making changes.

Step 1: Temporarily Disable Sedlauncher.exe Using Task Manager

Disabling sedlauncher.exe temporarily helps to quickly reduce CPU usage. Here’s how to do it:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click on the Processes tab.
3. Look for sedlauncher.exe or Windows Remediation Service in the list.
4. Right-click on it and select End task.

This stops the process for the current session, but it may restart after reboot. Use this method if you need an immediate but temporary fix.

Step 2: Disable Sedlauncher.exe Permanently via Services

To prevent sedlauncher.exe from running and consuming CPU resources every time you start your PC, disable its related service:

1. Press Windows + R to open the Run dialog box.
2. Type services.msc and press Enter.
3. In the Services window, scroll down and find Windows Remediation Service.
4. Right-click on it and choose Properties.
5. Under the Startup type dropdown, select Disabled.
6. Click Stop if the service is running, then click OK.

This action stops the service from starting automatically, which reduces CPU usage caused by sedlauncher.exe.

Step 3: Remove Sedlauncher.exe by Uninstalling Windows Update Remediation Package

sedlauncher.exe is part of the Windows Update Remediation component. If you want to completely remove it, follow these steps:

1. Open Settings by pressing Windows + I.
2. Go to Apps > Installed apps.
3. In the search box, type Update Stack Package or Windows Update Remediation.
4. If found, click on the entry and select Uninstall.

Uninstalling this package stops sedlauncher.exe from running but may affect Windows Update functionality. Only proceed if you are comfortable managing updates manually.

Step 4: Use Command Prompt to Disable Sedlauncher.exe

For users comfortable with command-line tools, this method disables the service quickly:

1. Press Windows + X and choose Windows Terminal (Admin) or Command Prompt (Admin).
2. Type the following command and press Enter:

sc config sedlauncher start= disabled

3. Next, stop the service by typing:

sc stop sedlauncher

This command disables and stops the service, preventing it from running on startup.

Sometimes, high CPU usage related to sedlauncher.exe may be caused by malware disguising as this legitimate process. To be safe:

• Run a full system scan using Windows Defender or your preferred antivirus software.
• Make sure your antivirus definitions are up to date before scanning.
• Remove any threats found to ensure your system is clean.
