keys.express und keys.discount sind Webplattformen für Product Keys. Die in unseren Shops erhältlichen Product Keys für Windows sowie weitere Software sind günstig, sicher, legal und mit Aktivierungsgarantie.
Nachfolgend finden Sie die wichtigsten rechtlichen Informationen zu unseren Produkten.
Wir bieten ausschließlich unbenutzte und nicht aktivierte Product Keys an. Die Keys wurden noch nie zur Aktivierung eingelöst und stehen dem Erwerber vollständig zur erstmaligen Aktivierung des jeweiligen Produkts zur Verfügung. Ein bereits eingelöster Key wäre für eine neue Aktivierung nicht mehr verwendbar und wird von uns deshalb nicht angeboten.
Der Handel mit diesen Product Keys ist in der Europäischen Union sowie in der Schweiz nach aktueller Rechtsprechung zulässig, sofern die notwendigen Voraussetzungen erfüllt sind. Diese lauten wie folgt:
Dieser Handel ist rechtlich zulässig, weil die zugrunde liegende Lizenz bereits mit Zustimmung des Rechteinhabers im EU-/EWR-Raum bzw. in der Schweiz gegen eine angemessene Vergütung in den Verkehr gebracht wurde. Damit ist der sogenannte Erschöpfungsgrundsatz eingetreten, der den Weiterverkauf einzelner Product Keys – insbesondere aus Volumenlizenzverträgen – erlaubt. Microsoft bzw. der jeweilige Softwareanbieter hat hierfür bereits eine angemessene Vergütung erhalten.
keys.express und keys.discount achten darauf, dass die vorgenannten Voraussetzungen erfüllt sind und ein legaler Gebrauch der Software sichergestellt ist. Die Voraussetzungen aus der europäischen Gesetzgebung werden auch in der Schweiz eingehalten.
Wichtiger Hinweis: Der Erwerb eines Product Keys durch Übermittlung einer Zahlen-/Buchstabenkombination in digitaler Form stellt für sich genommen noch keine Lizenz zur rechtmäßigen Nutzung des Programms dar. Die Lizenz bildet sich erst aus der jeweiligen Installation und der damit verbundenen Akzeptierung der Nutzungsbedingungen des Herstellers.
