Known Issues

1. Quiet sound in games and loss of sound effects

Microsoft has received user reports of unexpectedly quiet sound levels in certain computer games. Redmond added sound play changes in the latest update that “allow some games to request support and rendering of multi-channel audio”.

Microsoft plans to roll back these changes because “the rendering of multi-channel audio in some games and on some devices does not meet expectations”.

Temporary solution

Microsoft suggests disabling multichannel audio support in the game settings, if available in the affected game. An alternative is suggested to open Control Panel on Windows and forcibly disable multichannel sound or virtual surround sound for these games (if the manufacturer added such a function to the control panel).

2. Chinese IME input method may cause increased processor load

The Chinese IME input method (there may be other IMEs) may lose responsiveness and cause increased CPU utilization on Windows 10 May 2019 Update (1903) systems. Microsoft notes that the problem affects CHS (Chinese Simplified) and CHT (Chinese Traditional) with Changjie / Quick keyboards.

Temporary solution

Microsoft offers the following solution:

  • Click Start
  • Enter services.msc and press Enter
  • Find a record Touch Keyboard and Handwriting Panel Service and double click on it
  • In field Launch type select option Manually
  • Click ОК
