Si votre PC est li\u00e9 \u00e0 un compte Microsoft (que ce soit une version Pro ou non), Windows active automatiquement le chiffrement du disque. La cl\u00e9 de d\u00e9chiffrement est alors stock\u00e9e dans votre compte Microsoft.<\/p>\n\n\n\n
Nous rencontrons r\u00e9guli\u00e8rement des utilisateurs dont les informations de r\u00e9cup\u00e9ration (adresse e-mail ou num\u00e9ro de t\u00e9l\u00e9phone de secours) sont obsol\u00e8tes. Si vous ne pouvez plus acc\u00e9der \u00e0 votre compte Microsoft depuis un autre appareil, vous perdrez l\u2019acc\u00e8s \u00e0 votre cl\u00e9 de d\u00e9chiffrement\u2026 et donc \u00e0 toutes vos donn\u00e9es.<\/p>\n\n\n\n
Ces derni\u00e8res semaines, plusieurs utilisateurs nous ont contact\u00e9s apr\u00e8s avoir \u00e9t\u00e9 invit\u00e9s \u00e0 saisir leur cl\u00e9 de d\u00e9chiffrement suite \u00e0 une mise \u00e0 jour de Windows. L\u2019\u00e9cran bleu qui s\u2019affiche peut provoquer une vraie panique.
En entreprise, l\u2019administrateur peut r\u00e9cup\u00e9rer toutes les cl\u00e9s BitLocker via l\u2019interface d\u2019administration. Mais pour les particuliers, seul le propri\u00e9taire du compte Microsoft peut y acc\u00e9der.
Probl\u00e8me : beaucoup d\u2019utilisateurs cr\u00e9ent un compte Microsoft lors de la premi\u00e8re utilisation de leur PC\u2026 et l\u2019oublient compl\u00e8tement des ann\u00e9es plus tard.<\/p>\n","protected":false},"excerpt":{"rendered":"
