Windows 10 receives another update. The KB4515384 patch package is primarily a monthly set of security patches, but Microsoft has also released an important performance related update.
After installing KB4515384, users of Windows 10 1903 should no longer experience problems with unreasonable CPU usage. It is worth recalling that as a result of a malfunction and incorrect operation SearchUI.exe, the computer processor may have been unnaturally loaded, which could be felt as a decrease in system performance. By the way, the taskbar search engine was not able to provide relevant results.
Thus, previous assumptions that the correction of the described error will appear together with the September security updates have been confirmed. Previously, Microsoft did not provide a specific date when the patch will be released – it was only said about "mid-September".
