[TODO]: Create cleaner for Korg driver uninstall as it (potentially?) messes up other WinMM ports #602
Description
The Korg driver uninstallation appears to create a "midi0" entry. "midi0" is invalid, it should be "midi".
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
Mididiag output: Note the "midi0" entry. This should be "midi"
reg_drivers32_entry : MidisrvTransferComplete = 1
reg_drivers32_entry : midi0 = wdmaud2.drv
reg_drivers32_entry : midi1 = wdmaud.drv
reg_drivers32_entry : midi2 = wdmaud.drv
reg_drivers32_entry : midi3 = wdmaud.drv
reg_drivers32_entry : midi4 = wdmaud.drv
reg_drivers32_entry : midi5 = wdmaud.drv
reg_drivers32_entry : midi6 = wdmaud.drv
As a result, it can cause wdmaud2.drv to not be seen by Windows, and the WinMM endpoints will not work.
A correct restoration of properties would have midi set to wdmaud.drv and midi1 set to wdmaud2.drv. Doing that restores WinMM functionality.

Recording this here as I'll likely need to create a cleanup tool for this, and other customers should be aware.
