    Today I started getting this CertificateServicesClient-AutoEnrollment event id 64 on my desktop PC. I was able to track it down using MMC > Add/Remove Snap-in > Certificates. It was a certificate under Certificates > Personal > which was set to expire on 7-1-2018. No clue what this certificate is or where it came from, so I exported it, then deleted it and on reboot event id 64 warning disappeared.

    Does anyone know what the certificate ( is or what it's for ???

    1. I'm not recommending this as fix, just what I found and did.
    2. If you have this certificate it probably won't have the same prefix number as mine.
    3. I checked my Laptop PC and it didn't have this certificate.

    Removing this key did not gave me any troubles, so far ..........
