I would like to ask a question, that is, Windows 7, if not my notebook TPM hardware, how do I start it BitLocker encryption? I have seen in Vista Group Policy on the need to close a number of options, but I did not find a Windows 7-related settings.

Hi ZhenXuan, To enable Bit Locker without a TPM chip, please do the following: gpedit.msc > Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives > Require Additional Authentication at Startup > Enable Hope this helps.Jabez Gan [MVP] - http://www.msblog.org Contributing Author for: (Sybex) MCTS: Windows Server 2008 Applications Infrastructure Configuration Study Guide: Exam 70-643
