Known issues in this update

Symptom	Workaround
Microsoft has received reports that audio in certain games is quieter or different than expected after installing this update. At the request of some of our audio partners, we implemented a compatibility change that enabled certain games to query support and render multi-channel audio. Due to customer feedback, we are reverting this change as some games and some devices are not rendering multi-channel audio as expected. This may result in games sounding different than customers are used to and may have missing channels.	This issue is resolved inKB4517211.
Some Input Method Editor (IME) may become unresponsive or may have high CPU usage. Affected IMEs include Chinese Simplified (ChsIME.EXE) and Chinese Traditional (ChtIME.EXE) with Changjie/Quick keyboard.	Due to security related changes in this update, this issue may occur when the Touch Keyboard and Handwriting Panel Service is not configured to its default startup type of Manual. To resolve the issue, perform the following steps: Select theStartbutton and type “services”. Open the Services app and locateTouch Keyboard and Handwriting Panel Service. Double-clickTouch Keyboard and Handwriting Panel Serviceand selectProperties. LocateStartup type: and change it toManual. SelectOK. The TabletInputService service is now in the default configuration and IME should work as expected.
The print spooler service may intermittently have issues completing a print job and may result in a print job being canceled or failing. Some apps may close or generate errors when the print spooler fails and you may receive a remote procedure call error (RPC error) from some printing utility or printing apps.	This issue is resolved inKB4524147.
When setting up a new Windows device during the Out of Box Experience (OOBE), you might be unable to create a local user when using Input Method Editor (IME). This issue might affect you if you are using the IME for Chinese, Japanese, or Korean languages. Note This issue does not affect using a Microsoft Account during OOBE.	This issue is resolved inKB4530684.
