How to Enable Bitlocker for Windows 8 without TPM

BitLocker is probably one of the most important single advances in computing security. It is the requirement now for all the serious enterprises using windows systems. Read this post to understand more about BitLocker.
If you have windows 8, you will notice it will try to enable BitLocker with TPM, which is a property of the processor. The possibility to marry a software security encryption and a processor dispositive is perfect.
But what if your tablet/notebook does not have a processor TPM-enabled? If one try, it might see this message.
this device can't use a trusted platform module. your administrator must set allow bitlocker without a compatible tpm option in the require additional authentication at startup policy for OS volumes.
Here’s how to enable BitLocker for windows 8 in these cases.
In your windows 8, call the gpedit.msc.
in the group policy manager navigate to Computer Configuration/Administrative Templates/Windows Components/BitLocker Drive Encryption/Operating System Drives. Once there, double-click the option Require additional authentication at startup
Choose the option Enabled and in the options pane select the checkbox Allow BitLocker without a compatible TPM.
That’s it. Your device is now ready to be encrypted with BitLocker. Right-click your disk and the option to Turn on BitLocker will be available.
You will need to keep a USB memory stick to save your BitLocked credentials. Additionally you can save to a file and upload this file to your preferred storage location.
