Windows 10: How to get access to the account on encrypted laptop

I have a problem with access to my account. I use Lenovo Thinkpad running Microsoft 10, which I received from another person. The laptop is encrypted but everything had worked without problems until I decided to add another user account on the same machine. I logged in this new account, then I switched users to log in my old account but it is no longer available because it requires the password, which I don’t know. I tried my Microsoft account credentials, my local user name and local password. No effect. My old account is an administrator account so I cannot change anything from the other user account. Please help to get my account back.

Software encryption

read this:
The Encrypting File System (EFS) is a file system driver with filesystem-level encryption available in Microsoft Windows (2000 and later) operating systems, except Windows XP Home Edition, Windows Vista Basic, and Windows Vista Home Premium. The technology transparently allows files to be encrypted on NTFS file systems to protect confidential data from attackers with physical access to the computer.

User authentication and access control lists can protect files from unauthorized access while the operating system is running, but are easily circumvented if an attacker gains physical access to the computer. One solution is to store the files encrypted on the disks of the computer. EFS does this using public key cryptography, and aims to ensure that decrypting the files is in theory impossible without the correct key. However, EFS is in practice susceptible to brute-force attacks against the user account passwords. In other words, encryption of files is only as strong as the password to unlock the decryption key.

Partial Encryption of Laptop


Hi all.

I use to use TrueCrypt so that I could have only part of my laptop encrypted, and now TrueCrypt is no more *Sad.

Any help really appreciated!
