Windows 10: Cannot delete certificate [certmgr.msc]

    Cannot delete certificate [certmgr.msc]


    I have a certificate that I want to delete from the Windows Certificate Manager [certmgr.msc]; the certificate is called "User" as you can see from the screenshot.

    When I right click on it I don't see 'Delete'. If I right click on the other certificates I have the option to delete those.

    I know that I can safely delete this certificate but I don't know how. I've:


    • Launched certmgr.msc via Run
    • Launched certmgr.msc via the MMC
    • Elevated certmgr.msc to admin via my limited user account
    • Logged into my admin account to open certmgr.msc
    • Used certutil.exe to try and delete the certificate


    The option to delete is never available.

    I read on this thread that

    "Status = "R" if the Certificate Store is Read Only or if the certificate cannot be deleted."

    Does anybody know how I can delete this certificate from my system?

    Why do you want to delete it for? It looks like it is for EFS.

    You're right, it is for EFS.

    I don't use EFS as it's a nuisance and can lead to data loss and all sorts of complications. This certificate was generated very recently after I downloaded a program which activated EFS for its files.

    Anyway I've checked my hard drive and no files are encrypted by EFS and I therefore want to delete this certificate. I've done it before with no problems; I don't know why I can't now.

    I don't want to be hammered for this but, read up on Attrib -r.

    It's a dos level attribute changer, exact command for your situation would require my access to Windows.

    That won't happen for @ least 3 days, on vacay and bored with iPhone.

    I'm familiar with the attrib command but it does not help in this situation. The certificates are not accessible, as far as I can tell, via DOS. It's been locked by the OS and I need to unlock it. I've a sneaky suspicion they may be held in the TPM or registry.

    I know it may be quite a technical question outside of the scope of this forum (and more suited to TechNet) but I'd be interested in hearing if anybody else has suffered from this problem?

    I've only deleted, when logged in with CAC smart card.

    You should in theory be allowed to lose it, if logged in as administrator.

    Answer is not only technet, also superuserCannot delete certificate [certmgr.msc]

    Because it's a personal computer I'm not using a CAC. But the way CACs work is by authorising you against the central domain, which is effectively what I'm doing anyway (because I'm not on a domain-managed system).

    I've elevated to Admin but the certificate disappears: this is an intended behaviour. It's clearing the 'R' attribute that I need help with.

    I may try SuperUser unless anybody has any suggestions?
