All sorts of problems can occur when trying to record sound. At times, the problems can be isolated with some software, yet, at other times, they occur across the board. Nevertheless, a good place to test microphone recording problems with Windows is through viewing what options are available in the ‘Sounds and Devices’ located in the Control Panel. You can check to see the volume levels and what recording/playback options are selected. For example, selecting ‘Mic in Volume’ and setting the volume slider to the appropriate position could get the sound working again.
