Enable VT (Virtual Technology) on Your Computer

VT is the abbreviation of Virtualization Technology. Formerly known as Vanderpool, this technology enables a CPU to act as you have several independent computers, in order to enable several operating systems to run at the same time on the same machine.


The Android system of the Android emulator is not the same as the Windows system we use. The Android system on the emulator is run on a virtual "computer". Therefore, turning on the VT will better make use of the resources of the CPU on your computer. This technology does not have a bad influence on your computer equipment.


1. Check Whether VT is Supported or Enabled on Your PC.

Does your computer support VT? Or has your computer already enabled VT and you don’t know? It won’t be a concern if you download LeoMoon-CPU-V to check your computer. It is the only application on the Internet that will help you to detect if your CPU supports Hardware Virtualization. This program is 100% clean. It should work like the following

In the BIOS, VT section is usually named Intel(R) Virtualization Technology, Virtualization, Virtual, VT-X or SVM. Generally, you can find it in the “Processor Configuration” of the “Advanced” option.
