BitLocker® feature in Windows® 7
Microsoft has markedly improved Windows Vista BitLocker in its latest operating system, Windows 7, to be released officially on October 22.
The tool, which is the best solution for Drive Encryption, is available in the Ultimate edition that helps the user by encrypting the entire data. Once you turn on the BitLocker, any file on the drive will be automatically encrypted.
BitLocker feature in Windows Vista was too complex as the user first needed to shrink the partition to create the partition for BitLocker which took a lot of energy from the user, but this is quite simplified in Windows 7. You simply have to go to System and Security in the control Panel, turn on the BitLocker and the rest will be done by Drive Preparation tool.
Unlike Windows Vista, BitLocker partition is already available in Windows 7. The tool can easily boot up. It takes only 30 seconds in encryption process for 1 GB.
However, there are some system requirements to use BitLocker. Your computer should be provided with Trusted Platform Module running version 1.2 otherwise you need to save a start up key on a removable device. Primary Partition, at least of 1.5 GB, should be available which needs to be marked as active partition as it is used as boot manager to boot the system. And for data storage, you need another primary partition.
You can boot up Windows 7 once the system drive is encrypted, but USB stick should be present. If the system drive is not available, then you should know the Recovery Key or Recovery Password. Windows 7 selects 48 digits Recovery Password. New Group Policy settings has also been included in Windows 7 unlike Windows Vista. Moreover, the new operating system also supports New Recovery option, the Data Recovery Agent.
BitLocker To Go is a new feature of Windows 7 that gives lockdown treatment to the portable devices that can be easily misplaced.
