Microsoft To Fix Windows 10 “High CPU Usage” Bug

Written by Valdis Koks

Microsoft’s September patch set not only eliminated 79 vulnerabilities, 17 of which were critical, but also resolved the problem of sudden CPU load when using Cortana’s voice assistant.

This bug has annoyed Windows 10 version 1903 users for the past two weeks. Fortunately, Microsoft has acknowledged the problem. The cause of the atypical hopping load was the process of SearchUI.exe.

Complaints about the use of excessive CPU resources began to crumble literally after the KB4512941 patch was installed.

Recall that the problematic update was released on August 30.

It’s funny that with KB4512941, Microsoft initially wanted to fix a number of other bugs, but in fact created new ones.

Earlier, the corporation had promised to cope with the excessive consumption of CPU resources in mid-September. In fact, developers have done this even before – the 10th.
