Hardware devices installed for use with a Windows 7-based computer must have a specific driver to work properly. Drivers are sets of files that allow a device to interact with the motherboard and other components of the PC. If you recently uninstalled a microphone and desire to use it again, reinstall the computer drivers. The device manager utility within Windows 7 allows for easy installation of the most up-to-date drivers for a microphone to ensure the device is transmitting your voice clearly once again.
Click the "Start" button in the lower left hand corner of the Windows 7 desktop. Click the "Control Panel" option when the start menu appears. The control panel comes into view.
