Check out the list of free SoundFonts on the Coolsoft VirtualMIDISynth webpage. VirtualMIDISynth is an excellent replacement for the Microsoft GS Wavetable Synth (no longer installed with Windows). I use the Arachno SoundFont. Good sound quality without being huge. SoundFonts load into RAM. Depending on how much RAM you have, that may or may not be a problem. I'd be careful choosing a SoundFont if you have less than 32 GB of RAM.
