Does bitlocker work on Windows 7 professional?

I need to encrypt my hard drive.  I have Win 7 pro 64 bit.  Microsoft web site says bitlocker is in the control panel, and can be used in Win 7 ultimate and enterprise, not pro.  However, I see it under services.msc and it says I can use it to encrypt the OS and hard drives. Is this correct?  How do I encrypt it with this service?

Bitlocker does not work in Pro.  It does in Win8 Pro, but not Win7 Pro.  If using Windows 7, you need Enterprise or Ultimate.

So even though Win 7 pro has BitLocker Drive Encryption service, it can't encrypt using Bitlocker, is that correct?

Hi Maharlika,

Yes, You are correct. Windows 7 pro can't encrypt using Bitlocker.

BitLocker is unavailable for Windows 7 Professional and it cannot be downloaded and installed. Applies to these editions of Windows 7  Ultimate and Windows 7 Enterprise.

Thank You.
