If you no longer use virtualization-based security (VBS) with a virtual machine, you can deactivate VBS. When you deactivate VBS for the virtual machine, the Windows VBS options remain unchanged but might induce performance issues. Before deactivating VBS on the virtual machine, deactivate VBS options within Windows.


Ensure that the virtual machine is powered off.


  1. In the vSphere Client, browse to the virtual machine that is using VBS.
    See Identify VBS-Enabled Virtual Machines for help in locating virtual machines that use VBS.
  2. Right-click the virtual machine and select Edit Settings.
  3. Click VM Options.
  4. Deselect the Enable check box for Virtualization Based Security.
    A message reminds you to deactivate VBS in the guest OS.
  5. Click OK.
  6. Verify that the virtual machine's Summary tab no longer displays "VBS true" in the Guest OS description.
