//      as the initial tab. Setting this flag only displays the

//   WT_TRUSTDBDIALOG_WRITE_LEGACY_REG_FLAG

//              WinTrust\Trust Providers\Software Publishing\Trust Database\0"

//      of any previous publisher values.

//      location:
//          "HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\
