Hello @Yeshi Tshering , to find your bitlocker recover key using your student account follow the steps detailed in View or copy BitLocker keys. If none is found there's the chance somebody else enabled bitlocker and saved the recovery keys in his account or that it was not saved to the cloud in the first place. If you're still able to log into Windows then you can try disabling bitlocker on all data disks and finally on the OS disk.
