How to enable the virtualization technology function

Today, I installed a virtual machine on my computer, but I want to install a 64-bit win7 on the virtual machine, which always prompts:

Attempting to load a 64-bit application, however this CPU is not compatible with 64-Bit mode

After checking on the internet, I found that the computer's virtualization technology function was not enabled. Just find the corresponding item in Bois and set enable.

Finally, the 64-bit win7 system was successfully built on the virtual machine.
