I have successfully used Audacity in an education setting for many years. We have just upgraded to Win7 on new pcs. On trying to record on Audacity 2.0.0 all I get is a slightly wobbly blue line that is really static. I am using headset/mic to record my voice and have set preferences as recommended in the manual.

Describe the headset. Logitech? USB? Analog?
Your graphic cuts off the right-hand edge where we get to see what Audacity things it’s recording.
