  1. This feature is only available for Windows 10 Pro or Enterprise.
  2. To get the high-quality results to link yours with Trusted Platform Module (TPM) chip. This is a special microchip that enables your device to support advanced security features.
  3. It can be used without a TPM chip, but it might need extra authentication steps.
  4. Your computer’s BIOS must support TPM or USB devices.
  5. Two partitions must be present on your computer containing necessary files to start Windows and the partition with the operating system.
