Windows 10: August 30 Cumulative Update, raises CPU usage to 30-40% due to Cortana

New cumulative update for Windows 10, released on August 30, causes 30-40% CPU usage in the voice assistant Cortana.

The last update cumulative Windows 10 is causing problems. As usual, the latest update released by the company, which is cumulative, is causing many performance problems. Last Saturday Windows 10 Build 18362.329 was released, the cumulative KB4512941 generates high loads on the CPU. It poses a serious problem, because it is inefficient CPU usage for nothing.

KB4512941 began to be distributed on August 30, although it was yesterday when its distribution began to spread. Microsoft advertised it as an update that should fix remote desktop, Windows Sandbox, and other issues. Additionally, the note highlights that Edge would support ePUB files that use e-books in the coming months.

Cumulative update of Windows 10 generates excessive CPU usage

Windows Latest Medium said that many users report that they have high CPU usage after the update. It appears that this additional processor usage is due to a problem in Cortana. They report that the SearchUI.exe process of the virtual assistant uses 30-40% of the CPU, as well as 150-200MB of RAM. Logically these resources do not do useful work.

It is not clear why the Cortana process consumes so many resources after KB4512941. Members of Windows Insiders would have already reported the issue before the update came out. Therefore, we recommend not installing this update, as we are wasting processor power like hell.

We see how the Windows 10 updates from a few months ago, end up generating serious problems. It is best to let the unsuspecting update and report issues. The previous cumulative one prevented us from synchronizing peripherals via Bluetooth, something that was a major problem. We don't know what Microsoft is doing, but this is a very serious bungling for such a large company.
