Recently we have dozens of computers to remove the SCCM client. I don't want to manually uninstall it one by one. Could you please share a method to auto uninstall it?

    Hi, @QdPooler-5995

    Thank you for posting in Microsoft Q&A forum.

    An easy way to uninstall the client is run the script for a device collection you want to uninstall the client:

    C:\Windows\ccmsetup\ccmsetup.exe /uninstall  


    If we want to uninstall the client completely, we need to delete the related folders and registry with another script:

    # Delete the folder of the SCCM Client installation: "C:\Windows\CCM"  
    Remove-Item -Path "$($Env:WinDir)\CCM" -Force -Recurse -Confirm:$false -Verbose  
    # Delete the folder of the SCCM Client Cache of all the packages and Applications that were downloaded and installed on the Computer: "C:\Windows\ccmcache"  
    Remove-Item -Path "$($Env:WinDir)\CCMSetup" -Force -Recurse -Confirm:$false -Verbose  
    # Delete the folder of the SCCM Client Setup files that were used to install the client: "C:\Windows\ccmsetup"  
    Remove-Item -Path "$($Env:WinDir)\CCMCache" -Force -Recurse -Confirm:$false -Verbose  
    # Delete the file with the certificate GUID and SMS GUID that current Client was registered with  
    Remove-Item -Path "$($Env:WinDir)\smscfg.ini" -Force -Confirm:$false -Verbose  
    # Delete the certificate itself  
    Remove-Item -Path 'HKLM:\Software\Microsoft\SystemCertificates\SMS\Certificates\*' -Force -Confirm:$false -Verbose  
    # Remove all the registry keys associated with the SCCM Client that might not be removed by ccmsetup.exe  
    Remove-Item -Path 'HKLM:\SOFTWARE\Microsoft\CCM' -Force -Recurse -Verbose  
    Remove-Item -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\CCM' -Force -Recurse -Confirm:$false -Verbose  
    Remove-Item -Path 'HKLM:\SOFTWARE\Microsoft\SMS' -Force -Recurse -Confirm:$false -Verbose  
    Remove-Item -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\SMS' -Force -Recurse -Confirm:$false -Verbose  
    Remove-Item -Path 'HKLM:\Software\Microsoft\CCMSetup' -Force -Recurse -Confirm:$false -Verbose  
    Remove-Item -Path 'HKLM:\Software\Wow6432Node\Microsoft\CCMSetup' -Force -Confirm:$false -Recurse -Verbose  
    # Remove the service from "Services"  
    Remove-Item -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\CcmExec' -Force -Recurse -Confirm:$false -Verbose  
    Remove-Item -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\ccmsetup' -Force -Recurse -Confirm:$false -Verbose  
    # Remove the Namespaces from the WMI repository  
    Get-CimInstance -query "Select * From __Namespace Where Name='CCM'" -Namespace "root" | Remove-CimInstance -Verbose -Confirm:$false  
    Get-CimInstance -query "Select * From __Namespace Where Name='CCMVDI'" -Namespace "root" | Remove-CimInstance -Verbose -Confirm:$false  
    Get-CimInstance -query "Select * From __Namespace Where Name='SmsDm'" -Namespace "root" | Remove-CimInstance -Verbose -Confirm:$false  
    Get-CimInstance -query "Select * From __Namespace Where Name='sms'" -Namespace "root\cimv2" | Remove-CimInstance -Verbose -Confirm:$false  
    # Alternative command for WMI Removal in case of something goes wrong with the above.  
    # Get-WmiObject -query "Select * From __Namespace Where Name='CCM'" -Namespace "root" | Remove-WmiObject -Verbose | Out-Host  
    # Get-WmiObject -query "Select * From __Namespace Where Name='CCMVDI'" -Namespace "root" | Remove-WmiObject -Verbose | Out-Host  
    # Get-WmiObject -query "Select * From __Namespace Where Name='SmsDm'" -Namespace "root" | Remove-WmiObject -Verbose | Out-Host  
    # Get-WmiObject -query "Select * From __Namespace Where Name='sms'" -Namespace "root\cimv2" | Remove-WmiObject -Verbose | Out-Host
