Hi Guys, Is it possible using certutil or (other commandline operator) to delete all certificate in the "My" store from a specified issuer? I can easily delete by name or serial number but by issuer is seeming a little more difficult. Thanks

Hi, As far as I know, we can use PowerShell to delete certificate by Issuer. Try the following command: get-item cert:\CurrentUser\My\* | foreach{if($_.issuer -eq "ISSUER_NAME") remove-item $_} For more information, please refer to the following article. Certificate Provider http://technet.microsoft.com/en-us/library/dd347615.aspx Thanks. This posting is provided "AS IS" with no warranties, and confers no rights.

As a reminder, I'd like to state that making alterations in the registry are dangerous by nature and not supported by m$. Information is the most valuable commodity I know off.

Sorry for the delay in getting this post in, its been a while since I could address this topic. Thanks for the assistance Mervyn, however does this process remove the certs from the Computer\Personal store? Or does this remove from the User\Personal store? Im looking at removing from the computer store if that makes a difference. Thanks again

Acutally, just figured it out... Simply Replace CurrentUser with LocalMachine and there she be. Thanks again.

The certificate provider does not support Remove-Item - it's effectively a ReadOnly view. I used the following to delete certificates which uses a combination of what is listed here and on the following article: http://www.leeholmes.com/blog/2007/08/23/removing-certificates-from-the-certificate-store/ $storeNames = "My", "TrustedPeople" $storeLocation = "LocalMachine" "CN=Cert1", "CN=Cert2" | %{ $certCommonName = $_ $storeNames | %{ $storeName = $_ $location = "cert:\" + $storeLocation + "\" + $storeName Get-ChildItem $location | ?{ $_.Subject -eq "$certCommonName"} | %{ $cert = $_ $store = New-Object System.Security.Cryptography.X509Certificates.X509Store $storeName, $storeLocation $store.Open(ReadWrite) $store.Remove($cert) $store.Close() } } }
