Hi,

I want to know if there is a PowerShell command that can find and delete duplicate old machine certificates from the local machine store.

I want to know if there is a query to find devices with duplicate certificates in "Cert:\LocalMachine\My" location.

Thanks,
Muja

    Hi @Mujahith Muzamil ,

    You can filter out the subjects of duplicate values like this

    $certs = Get-ChildItem -Path "Cert:\LocalMachine\My"  
    $certs.subject | Where-Object { ($certs.subject -eq $_).Count -gt 1}  
    

    Hope this helps.

    Best Regards,
    Ian Xue

    Hi Ian Xue,

    Thanks for the quick update.

    I also want to know whether i could use this command to collect the device names with duplicate certificates using a SCCM Query.

    Thanks
