Can't Get Right Opengl Version

To get the compatibility profile context supported by the driver, I used something like this:

initializeOpenGLFunctions();
QString qVer = QString::fromLocal8Bit((char *)glGetString(GL_VERSION));

But on some machines(Windows 10)，I always get "OpenGL ES 2.0" by Qt while the real version is "1.0.0" or "4.3.0" by OpenGL Extensions Viewer.

Is there some other way I can get it?Thanks!
