In addition to the requirements above that are needed to run Windows, some features have additional requirements. In some cases, features included with updated versions of Windows 10 will be best experienced with newer processors. For specific hardware support please refer to your Original Equipment Manufacturer (OEM). Below are some additional details regarding requirements for key features:
- BitLocker Drive Encryption (available with Windows 10 Pro or Windows 10 Enterprise only) requires a Trusted Platform Module (TPM) 1.2 or higher and Trusted Computing Group (TCG)-compliant BIOS or UEFI. BitLocker can be used on devices without TPM, but you will need to save a startup key on a removable device such as a USB flash drive. TPM 2.0 and InstantGo support is required when you want to automatically encrypt the local drive when joining a device to Azure Active Directory (AAD). Check with your PC manufacturer to confirm if your device supports the correct TPM version and InstantGo for the scenario you want to enable.
- BitLocker To Go requires a USB flash drive (available in Windows 10 Pro and Windows 10 Enterprise only).
- Client Hyper-V requires a 64-bit system with second level address translation (SLAT) capabilities and additional 2 GB of RAM (available in Windows 10 Pro and Windows 10 Enterprise only).
- Cortana is only currently available on Windows 10 for the United States, United Kingdom, China, France, Italy, Germany, Brazil, Mexico, Japan, Canada, Spain, Australia and India.
- Microsoft account is required for some features.
