  1. Worked for me, since this addresses the cause of the issue.
    Note that the ‘Cryptographic Services’ needs to be stopped before and that the Windows security reorder dialog shows only after selecting Permissions… and trying to allow full permissions to the current user for the ProtectedRoots folder.

  2. To allow delete you may need to add Full Control permission to your account at HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\Root\ProtectedRoots
