Microsoft GS Wavetable Synth not available in Windows 8.1

Question

Hi,
Where should I go to ask the following question?
I'm writing a Web MIDI application (in Javascript) using the Web MIDI API.
Neither Jazz nor the Chrome Web MIDI implementation are finding the Microsoft GS Wavetable Synth on my Windows 8.1 laptop. Using the same web page, there's no problem on my Windows 7 machine.
Other users of Jazz and the Chrome Web MIDI implementation say that they are correctly finding the MS GS Synth on Windows 8.1, so the problem seems local.
I'm told (ultimately by a Yamaha engineer) that the probable cause is that the MS GS Synth has been locked by another program first.
Windows Media Player is playing MIDI files okay, so the MS GS Synth is there somewhere.
Suspecting that the problem lay in the direction of WMP, I tried disabling it and restarting without it. But the problem persists.
I've tried disabling all the startup processes in the Task Manager, and restarting, but this also does not help.
Where do I go from here?
