Need to find and delete the duplicate older machine certificates

Question

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

Answer 1

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

Answer 2

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
