Windows 7 new features: BitLocker

If you've got information on your PC that you need to protect, you can help prevent theft or loss by using BitLocker data encryption to put a virtual lock on your files.

How can you help protect your data from loss, theft, or hackers? The answer: BitLocker. If you've got information on your PC that you need to protect, you can help prevent theft or loss by using BitLocker data encryption to put a virtual lock on your files.

Improved for Windows 7 and available in the Ultimate edition, BitLocker helps keep everything from documents to passwords safer by encrypting the entire drive that Windows and your data reside on. Once BitLocker is turned on, any file you save on that drive is encrypted automatically.

BitLocker To Go—a new feature of Windows 7—gives the lockdown treatment to easily-misplaced portable storage devices like USB flash drives and external hard drives.

 BitLocker locks down all your drives, so your data is safe from prying eyes.
