I want to try out Windows 10s new file system ReFS. I have the latest Windows 10 Pro installed and created 2 vhdx virtual drives, as listed below:
ReFS is almost more than a decade old if you consider the fact Windows 8 was the first version of Windows to support it.
Unless you are running Windows 10 Enterprise or Windows 10 Professional for Workstations you won’t be able to create a new ReFS volume. Supported versions of Windows Server obviously also natively support the creation of ReFS volumes.
Does anyone know how I can activate this?
You must be using Windows 10 Professional for Workstations
Creation ability will be available in the following editions only: Windows 10 Enterprise and Windows 10 Pro for Workstations. Creation ability will be removed from all other editions. All other editions will have Read and Write ability.
An alternative solution to upgrading would be to format the virtual VHDXs as ReFS on a supported edition and simply attach them on an Windows edition that doesn’t directly fully support it.
