On OSX or linux, it is rather trivial to view CPU capabilities in the terminal. Is there a way to access the CPU information, specifically the hardware assisted virtualization capabilities, on Windows?
I only found Microsoft's tool: http://www.microsoft.com/en-us/download/details.aspx?id=592
but would like something that doesn't require additional binaries.

Visit the product specification site (ark.intel.com). Enter the number of the processor in the search box located on the right side. On the processor product page, and under Security & Reliability, check to see if Intel® Virtualization Technology (VT-x) is supported.
To check if Virtualization is enabled/disabled on your desktop/laptop, simply press Ctrl + Shift + Esc keys to open the Task Manager. Click on the Performance tab and under CPU, you will find information about Virtualization on your desktop/laptop. If it says Enabled, then Virtualization is turned on.
Solution: Using Task Manager Check the CPU details that are shown by-default as you open the Performance tab. Under CPU details on the right-side of the screen check the Virtualization section. It will show if it's Enabled or Disabled. Here, we can see it's Enabled.
Go to the download location and double-click the file to open it. Once open, click the CPU Technologies tab. See if the “Intel Virtualization Technology” box is marked. If it is, then Intel Virtualization Technology is enabled on your computer.
I believe the best bet to check if virtualisation is enabled is by using WMI and check the Win32_Processor class. The value of the "VirtualizationFirmwareEnabled" field should give you if it is enabled.
I have tested on my machine by enabling and disabling in the BIOS and this value appears correct.

For checking what is supported I believe you will need to use the __cpuid() intrinsic function with an Information type of 0x1 and 0x80000001 to query the CPU features. Examples can be found on the following links.
