Microsoft fixed IME High CPU usage and Start menu and Windows Desktop Search bug

Previously, Microsoft mentioned that the latest cumulative update of Windows 10 Version 1903 may cause the Start menu and Windows Desktop Search to be corrupted and some Input Method Editor to be abnormal. The start menu damage means that when the user clicks the start menu, the system automatically pops up a prompt saying that a serious error has occurred, requiring the user to log off and repair. After receiving some feedback from users, Microsoft will start troubleshooting. The Chinese input method problem is mainly due to the IMEs include Chinese Simplified (ChsIME.EXE) and Chinese Traditional (ChtIME.EXE) with Changjie/Quick keyboard. The main process abnormally occupies a large number of processor resources.

Microsoft’s explanation of the start menu corruption in the status dashboard is that the company has not yet discovered that the latest cumulative update has caused a large number of users’ start menus to fail to open. Although Microsoft has marked this issue as a solution, it is actually Microsoft has not found a problem, or Microsoft has not confirmed the existence of this problem. Microsoft also said it will continue to closely monitor the operation of the telemetry data to ensure that users can get a high-quality interactive experience when using features such as the Start Menu. As for the current user who does not have the normal start menu prompts and can’t open normally, Microsoft wants users to submit feedback in the Windows 10 Feedback Center. Microsoft wrote:

At this time, Microsoft has not found a Search or Start issue significantly impacting users originating from KB4515384. We will continue monitoring to ensure users have a high-quality experience when interacting with these areas. If you are currently having issues, we recommend you to take a moment to report it in via the Feedback Hub (Windows + F) then try the Windows 10 Troubleshoot settings (found in Settings). If you are having an issue with search, see Fix problems in Windows Search.

The Chinese input method process exception is actually caused by Microsoft’s security improvements, Microsoft said this is related to the latest cumulative update KB4515384 security improvements. Chinese users affected by this can solve the problem by manually modifying the service item.

To resolve the issue, perform the following steps:

1. Select the Start button and type Services.
2. Locate Touch Keyboard and Handwriting Panel Service and double click on it or long press and select Properties.
3. Locate Startup type: and change it to Manual
4. Select Ok
5. The TabletInputService service is now in the default configuration and IME should work as expected.
