HOW TO LOCK DRIVE WITH PASSWORD
Enable BitLocker
Overview
BitLocker Drive Encryption is a native security feature that is available in some versions of Windows.
It is a whole disk encryption solution; it encrypts everything on the drive that Windows is installed on.
When you enable BitLocker, you create a personal identification number (PIN), which you need to enter
every time you start up your computer. A recovery key is also generated. You can use the recovery key
to gain access to your computer if your forget your password. You should print the recovery key and store
it in a safe place., apart from your computer. After the recovery key is generated you will be prompted to
restart your computer. The encryption process starts when the computer reboots.
BitLocker is used in conjunction with a hardware component called a Trusted Platform Module (TPM).
The TPM is a smartcard-like module on the motherboard that is installed in many newer computers by
the computer manufacturers. BitLocker stores its recovery key in the TPM (version 1.2 or higher).
Requirements
To use BitLocker, your computer must satisfy certain requirements:
- Supported operating systems:
- Windows 8 — Professional or Enterprise edition
- Windows 7 — Enterprise or Ultimate edition

Additional requirements:
