OpenFOAM® Installation on Windows 10
From OpenFOAM-v1706, users can now run OpenFOAM using Bash on Ubuntu on Windows. This utility, referred to as the Windows Subsystem for Linux (WSL) uses the genuine Ubuntu image provided by Canonical, the group behind Ubuntu Linux. Bash on Ubuntu on Windows does not support graphics directly. For GUI-based processing users are recommended to download and use the ParaView Windows native build.
Activate Ubuntu Bash and create a user account. Note: this will require a computer reboot. Additional guidance can be found in https://msdn.microsoft.com/en-us/commandline/wsl/install_guide
