Programmatically determine if VT-x or AMD-v is enabled on Windows

Question

On OSX or Linux, it’s pretty trivial to look at the CPU capabilities in the terminal. Is there a way to access information about the processor, in particular, the capabilities of hardware support for virtualization, in Windows?

I found the Microsoft tool: http://www.microsoft.com/en-us/download/details.aspx?id=592

but would like something that does not require additional binaries.

Answer 1

I find it best to check if virtualization is allowed using WMI and checking the Win32_Processor class. The value of the "VirtualizationFirmwareEnabled" field should provide you, if enabled.
