Windows Update Improvements
Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.
Known issues in this update
|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:
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.
To mitigate this issue, set the keyboard language to English during user creation or use a Microsoft Account to complete OOBE. You can set the keyboard language back to your preferred language after user creation. Once the OOBE is done and you are at the desktop, you can rename the current user using these instructions. If you prefer to create a new local user, see KB4026923.
Microsoft is working on a resolution and will provide an update in an upcoming release.
