VMware Workstation 12.5.9 Pro represents the final build in the v12 series before the architecture shift to version 14 (which dropped support for older host CPUs). It is stable, reliable for legacy guest operating systems (Windows XP through 10 v1703, older Linux kernels), but suffers from critical security vulnerabilities and zero modern OS support. Its usage today is restricted to air-gapped legacy development environments or offline lab scenarios. Summary VMware Workstation Pro 12
