Summary of "Solved : Virtualized Intel VT-X/EPT is not supported on this platform"

Fix: “Virtualized Intel VT-x/EPT is not supported on this platform” (VMware Workstation)

Problem

VMware shows the error and the VM won’t start because the Windows hypervisor (Hyper‑V) is active on the host. Even if Hyper‑V appears unchecked in Windows Features, the hypervisor can still be detected by the system.

Example detection message: “Hyper-V has been detected” or “Hypervisor has been detected”

Quick checklist / steps (in order)

  1. Check whether Hyper‑V is active

    • Run: cmd systeminfo

      • Look for a line such as “Hyper-V has been detected”.

        • Or run: cmd msinfo32

      • Check the “Hypervisor has been detected” message in System Information.

  2. Switch off Hyper‑V using an elevated command prompt

    • Open Command Prompt as Administrator and run: cmd bcdedit /set hypervisorlaunchtype off

    • Note: this must be run as Administrator. If successful it will say “The operation completed successfully.”

  3. If the VM still shows the error, disable Hyper‑V via PowerShell

    • Open PowerShell as Administrator and run: powershell Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

    • This command will request a restart to complete the change.

  4. Restart Windows

    • Reboot the host machine after running the commands (either when prompted or manually).

  5. Start the VM in VMware Workstation

    • After the restart, the VM should start normally.
