Easy certificate export from IE internet options

If you were ever wondering why the export of certificates from Internet Explorer's internet options is so hard, check out this easy method with drag&drop.
btw: export as DER encoded binary is fine for Windows systems and to add a user certificate to one of your outlook contacts; base64 encoded is perfect for openssl-based applications or if you need to transfer a certificate via clipboard from your local host into a RDP-session or vice versa; export as PKCS#7 (p7b) is good if you need to export a user or machine certificate with the complete certificate chain. The exported p7b file is in binary format.
