BitLocker is the Windows encryption technology that protects your device from unauthorised access by encrypting your drive. BitLocker uses your Windows login to secure your data. When you are logged in, your files look just like they would otherwise, and when you log out, everything is secured. BitLocker will not affect the performance of your computer. 

When would I require the BitLocker key?

You may be prompted to provide a BitLocker recovery key when you make changes in hardware, firmware, or software which BitLocker cannot distinguish from a possible attack. In these cases, BitLocker may prompt for the recovery key even if the user is an authorised owner of the device. Such activities might be:

  • Updating the system’s UEFI/BIOS
  • Changing Secure Boot settings
  • Significant hardware modification (removal or addition of hardware)
  • Installing a Windows update that updates UEFI or TPM settings on device

How do I know if BitLocker is enabled on my device?

You can determine if Bitlocker is enabled by launching Explorer and checking if your drive has a padlock as shown in this diagram:BitLockerEnabled.png
