Help protect your files using BitLocker Drive Encryption - Microsoft Windows Help. You've used an alpha numeric password with other characters to prevent access to your notebook's hard drive - check. You use password and two step authentication on your major banking, social media, and other web sites on which you discuss personal or confidential data - check. You keep your tablet, phone and notebook computer within reach at all times - you don't? Uh oh. A thief could walk away with your device and steal your data. Solution? Use Android Device Manager to allow for remote location and wiping of the the device. After all that, you need a deadbolt lock for your data. That involves encrypting it, which you believe is complicated. But, wait. Windows 8, which I have been trying to get you to upgrade to, has built in drive encryption by BitLocker. Use it. Or lose it.
