One of the interesting features of Windows 7 is new improved BitLocker Windows Disk Encryption Tool. The exclusive feature is a part of Windows 7 Ultimate and Windows 7 Enterprise editions.

The purpose of BitLocker Windows 7 is to encrypt the drives of the computer so that their data can only be accessed after providing the correct password that can decrypt the data. If you have encrypted the drives of your system, there is no chance that your data is lost to unauthorized people. No one can access your data (unless they know the password), even if your laptop or removable drives are stolen.

BitLocker was introduced with Windows Vista (the previous Operating system of Windows) but it was not much liked by users because of its complicated procedure to use; while new Windows 7 BitLocker is quite easy and straight-forward. It provides a covering security to the users’ files. It can be used not only to protect files on computer disks but also to secure data by encrypting files on removable devices like SD Cards, Pen drives, etc; so in case of theft or lost, your data is not in the hands of strangers.

You can encrypt your files using BitLocker within minutes. Open My Computer and Right-click on the drive that you want to encrypt. Select Turn on BitLocker. Once BitLocker has initialized the flash drive, you will be prompted to enter a password. This password will be required later in order to unlock the drive.  You also have a choice set up a Smartcard.

After that you will need to store the recovery key which can be used in the event of forgetting your password or losing your smartcard.  In case, you store it as a file, ensure that you do not save it on the drive you are encrypting.

You will get a confirmation message after which your system will be ready to start encrypting the drive. You simply need to click the Start Encrypting button. Progress screen will be displayed on screen till the process goes on.

Although Microsoft has truly enhanced BitLocker, the main problem with this security application is its restricted reach. BitLocker is only included in two out of the six Windows 7 version. Only those two versions will be able to encrypt drives and portable devices, although decryption can be done in any of the edition. Overall, it is a very helpful application that will benefit thousands of users.
