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 in KB4517211.

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:

  1. Select the Start button and type “services”.

  2. Open the Services app and locate Touch Keyboard and Handwriting Panel Service.

  3. Double-click Touch Keyboard and Handwriting Panel Service and select Properties.

  4. Locate Startup type: and change it to Manual.

  5. Select OK.

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 in KB4524147.

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 in KB4530684.

How to get this update

Before installing this update

Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU and applying Microsoft security fixes. For more information, see Servicing stack updates.

If you are using Windows Update, the latest SSU (KB4515383) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog.
