After the cumulative update of Windows 10 1903 KB4512941 was published, users began complaining about Windows Desktop Search problems, as well as problems with heavy CPU use in Cortana.
High CPU usage in Cortana While the Cortana bug was resolved in the cumulative update for KB4515384, users still complained about the blankness of Windows Desktop Search and/or Start Menus when they tried to use it. This resulted Microsoft to publish a guide to how Windows Search problems can be resolved. Apart from the start menu and the searches, cumulative users of Chinese Simplified (ChsIME.EXE) and Chinese Traditional (ChtIME.EXE) IMEs experienced a high level of CPU use with the release of the Windows 10 1903 KB4516058. As of yesterday, Microsoft now considers these two problems as addressed, but one of them is likely not attractive to everyone.
Search and Start Menu problems solved in Windows Desktop
Microsoft has defined these as settled for the Windows Desktop Search and Start menu problems because they did not discover that search and start problems substantially affect the user in comparison to the KB4515384 update. If you still have problems with these Windows 10 functions, Microsoft proposes that you report them through the Feedback Hub or attempt the Windows Search Tips. We are also curious if you still experience this problem, so kindly let us know in your remarks.
Resolved elevated CPU use of Chinese IME
Contrary to the search and start menu problems, Microsoft has verified and recognized the elevated use of the Chinese IME CPU. Microsoft says that this issue has been caused by the safety changes in KB4515384, which have led to the elevated CPU use of this issue.
