Microsoft GS Wavetable Synth
A month ago I upgraded to Windows 10 and NWC played perfectly until yesterday. Since yesterday after starting NWC I get the message '' Microsoft GS Wavetable Synth out port falied". Now the computer doesn't play midi's of nwc files any more.
NWC is version 2.75.

May be relevant although I don't believe it has anything to do with it: Day before yesterday I brought the computer from my study to the living room where it played some music. No problem. I brought it back and then playing with NWC didnt work any more.

Any suggestions?

It smells as if your MicroSoft GS Wavetable Synth driver is corrupt.
You should be able to verify this in "Control Panel" - "Device Manager" - "Software Devices".
The driver for in Windows 10 (on my system) is "c_swdevice.inf", version: 10.0.10240.16384
If this device is not working properly, you could try to reinstall or repair it. Please refer to MicroSoft's instructions how to achieve this.

As an alternative you can always add Soundfont based midi to your pc. With this technology you can produce even better sounds than what is possible with MicroSoft. Free soundfont packs can be found under the links below or in conversations on this forum (soundfont is a good search criterium).
VirtualMidiSynth is very easy to configure and .
BassMidi is another driver but isn't as easy as VirtualMidiSynth
