Are your worried about your data loss, theft or hackers? Windows 7 can help you to protect data on your PC and portable storage devices against loss or theft with BitLocker. BitLocker a new feature of Windows 7 helps keep everything from documents to passwords safer by encrypting the entire drive where your data resides. You can use BitLocker Drive Encryption to help protect all files stored on the drive where Windows is installed and on fixed data drives (such as internal hard drives). You can even protect all files stored on removable data drives such as external hard drives or USB flash drives.
If you encrypt the operating system drive, BitLocker checks your computer during startup for any conditions that could represent a security risk. If it detects potential security risk, BitLocker will lock the operating system drive and require a special BitLocker recovery key (which you can create when you turn on BitLocker for the first time) to unlock it. Unlike file system encryption which enables you to encrypt individual files, BitLocker encrypts the entire drive. This means even if you hard drive is stolen; nobody can access the data inside the drive.
BitLocker is only available in the Ultimate and Enterprise editions of Windows 7. To setup,
1) Open BitLocker Drive Encryption by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Security and then clicking BitLocker Drive Encryption.
2) Click Turn On BitLocker. This opens the BitLocker setup wizard. Administrator permission required If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
