On September 10, Microsoft released another update, KB4515384 (OS Build 18362.356), to solve the high CPU usage caused by SearchUI.exe. In addition, this update also included protections against security vulnerabilities and security updates for the Microsoft Edge browser and other applications.
Unfortunately, this update also triggered some problems. For example, it caused new search problems, broke the Start menu, Action Center and USB connections, and also caused audio problems.
On August 30, Microsoft released an update, KB4512941 (OS Build 18362.329), which aims to resolve problems such as high CPU usage caused by switching applications, an issue that certain games are prevented from leveraging Spatial Audio capabilities, blank tiles appearing in the Start menu, etc.
High CPU usage is a common problem that happens to PCs. The latest Windows 10 KB4512941 update also leads to this issue, but you can find solutions to fix it.
However, this update also triggered two problems. The one is that the resulting images may have an unnatural orange tint when you create screenshots or use similar tools, which is caused by the Eye Care mode feature of Lenovo Vantage.
The other problem is that a small number of users may not receive results when using Windows Desktop Search and may see high CPU usage from SearchUI.exe. This issue only occurs on devices that have disabled searching the web using Windows Desktop Search.
