How Can You Encrypt Files and Folders in Windows 10, 8 or 7?
You can encrypt files and folders in Windows (vers. 7-10) using BitLocker. This Vista operating system extension has on-disk encryption as well as key management capability. It’s protected by two-factor authentication, so anyone who wants to crack the code needs a hardware key and your specified long passphrase.
Through its trusted platform module (TPM) hardware, BitLocker provides advanced security features. For instance, when encryption is only at the software level, access may be vulnerable to dictionary attacks. Hardware-level protection safeguards your system from guessing or automated attacks.
What Steps Let You Check For a TPM Chip?
Follow these steps to see if your computer has a TPM chip:
- Select the Windows key + X and choose Device Manager.
- Expand on Security devices.

BitLocker is typically available on these platforms:
- Windows 10 on Enterprise, Pro, and Education
- Windows Vista and Windows 7 on Ultimate and Enterprise
- Windows 8 and 8.1 on Enterprise and Pro
- Windows Server 2008 and later
