Public Key Infrastructure (PKI) certificates are digital credentials that bind a public key to an identity. They are used to verify the identity of a website, server, or user. Over time, old PKI certificates can accumulate and become a security risk. Deleting old PKI certificates can help to improve security and reduce the risk of a data breach.
There are a few different ways to delete old PKI certificates. One way is to use the Certificate Manager in Windows Server. Another way is to use the command line tool Certmgr.exe. You can also use a third-party tool to delete old PKI certificates.
