How to Uninstall SCCM Client

The System Center Configuration Manager (SCCM) client plays a crucial role in managing devices in enterprise environments. However, there may be scenarios where you need to uninstall the SCCM client, such as troubleshooting, preparing for a reinstallation, or removing it from a system. This comprehensive guide walks you through various methods to safely uninstall the SCCM client from Windows devices.

Why Uninstall the SCCM Client?

Before diving into the uninstallation steps, it’s essential to understand the common reasons for removing the SCCM client:

• Resolving client-side issues or errors.
• Reinstalling the client to fix corrupted files.
• Transitioning to another device management solution.
• Removing SCCM management from decommissioned devices.

Prerequisites

• Administrator Access: Ensure you have administrative privileges on the system.
• Backup Important Data: While the uninstallation process doesn’t delete user data, it’s a good practice to back up critical files.
• Check Dependencies: Verify that the device is no longer actively managed by SCCM.

How to Uninstall the SCCM Client

Method 1: Uninstall Using Command Prompt

The quickest way to remove the SCCM client is through the command line.

1. Open Command Prompt:
   • Press Windows + R, type cmd, and hit Enter.
   • Run the Command Prompt as an Administrator.
2. Execute the Uninstall Command:
   CCMSetup.exe /uninstall
   By default, the CCMSetup.exe file is located in the C:\Windows\ccmsetup directory. If it's in a different location, navigate to that directory before running the command.

   The uninstallation may take a few minutes. You can monitor progress in the logs located at: C:\Windows\CCMSetup\Logs
4. Verify Removal:
   Open the Control Panel or check C:\Windows to ensure the CCM and ccmsetup folders are gone.

Method 2: Remove SCCM Client Using PowerShell

PowerShell provides another straightforward approach to uninstall the SCCM client.

1. Launch PowerShell:
   Press Windows + X and select Windows PowerShell (Admin).
2. Run the Uninstallation Command:
   Invoke-Command {C:\Windows\ccmsetup\CCMSetup.exe /uninstall}
3. Confirm Uninstallation:
   Once the command completes, verify that the SCCM client has been removed.

Method 3: Manually Remove SCCM Client

If the automated methods fail, you can manually remove the SCCM client.

1. Stop Related Services:
   Open Services.msc and stop the SMS Agent Host service (CcmExec).
2. Delete SCCM Folders:
   Remove the following directories:
   • C:\Windows\CCM
   • C:\Windows\ccmsetup
   • C:\Windows\System32\CCM
3. Remove Registry Entries:
   Open the Registry Editor (regedit) and delete these keys:
   • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CCMSetup
   • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS
4. Restart Your Computer:
   Reboot to ensure all changes are applied.

Method 4: Use SCCM Cleanup Tools

For a more streamlined process, you can use tools designed to cleanly uninstall the SCCM client:

Things to Consider After Uninstallation
