Enabling BitLocker to Secure Microsoft Windows

Enabling BitLocker in your Microsoft Windows OS is a good step to secure it especially if it’s installed on laptop or other portable devices that is easily to be stolen. Once you have enabled it, it will encrypt all files stored on the drive Windows is installed on, so that all these files and drives cannot be accessible by unauthorized users if your laptop is stolen. This is important security feature which you should enable especially if you store important and sensitive files on your laptop.


Once you have enabled it, you can log on and work with your files normally, but BitLocker can help block hackers from accessing the system files they rely on to discover your password or from accessing your drive by removing it from your computer and using it on other computers.

BitLocker uses a TPM (Trusted Platform Module) to provide this full disk encryption protection for your data, and so your laptop must support TPM in order to use this advanced security feature. Please note BitLocker can only be enabled in Windows Vista Ultimate or Enterprise editions, Windows 7 Ultimate or Enterprise editions and Windows 8 Pro or Enterprise editions.
