Im looking for a cw decoding software that I can use my computer microphone to listen to the Morse code and have what is being sent, decoded on my computer screen. Does anyone know of such a software?

This is a very frequently asked question. Many of the digital mode programs will decode CW after a fashion. The best one I've found is a dedicated program called MRP40.

cwget for Windows, and fldigi for Linux.
cw skimmer is pretty good. A license costs $75.00 . HRD and fldigi are free, but don't do very well decoding cw sent with a straight key. They work fine for computer or electronic keyer generated code that is 20 db's or so over the noise level. If you want to decode most anything, cw skimmer, cw get and Mrp-40 are commercial apps that you have to buy, but they have much better decoders than hrd and fldigi. Mrp-40 is better at weak signal cw decoding than cw skimmer, but cw skimmer let's you decode everything in the passband at once.
If you are running Linux, fldigi is the only choice. On a Mac, cocoa modem is on par with fldigi, but can't decode as well as cw skimmer, cw get and mrp-40. None of the apps work well with fading signals or with interference, or noisy band conditions.
