Users not experiencing any issues at the moment with Windows 10 might want to hold off installing the optional KB4512941 (August 30th) update until Microsoft fixes the issue.Windows Latest said that numerous people have complained about high CPU usage problems after installing the update, however, purportedly because of an issue with Cortana. The virtual assistant's SearchUI.exe process has reportedly used 30-40% of the CPU as well as 150-200MB of memory since the installation of the KB4512941 update. But those resources are being totally wasted--the Cortana window opened from the Taskbar fails to load.
It's not clear why Cortana decided to be a processor hog with the KB4512941 update. What is clear, however, was the fact that members of the Windows Insider Program reported these problems to Microsoft via the Feedback Hub before the update was made available to the public. Those reports appear to have slipped through the cracks; now people who install the optional update are sacrificing a significant portion of their CPU to Cortana.
