"After installing KB4512941 (OS Build 18362.329) the pop-out window with the search results stays blank, SearchUI.exe is constantly using CPU and ~200MB of memory", a user documented the problem on Microsoft's Feedback Hub.
With high-speed internet now becoming more widely available, users would be able to download a clean copy of Windows 10 in no time.
Microsoft has been drip-feeding new updates into Windows 10 for years but one feature, the Snip & Sketch tool, has been neglected for far too long.
Some recent reports suggest that the installation of this update causes a high CPU usage for many users.

According to Net Applications, in August, Windows 7 dropped to 30.34%, a loss of 1.49%. Additionally, Feedback Hub reports mirror complaints that the Search button next to the Start Menu isn't working. The first is to simply uninstall KB4512941, but as the update addresses a number of other issues, this is probably not the best idea.
You can resolve the problem by enabling Bing search and by replacing Cortana Cache folder with an older version.
To rectify the problem, you can enable BingSearch by configuring the BingSearchEnabled value to 1 under the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search Registry key.
Why did Microsoft release the update anyway? To do so, open up Settings (WIN + I), select Update & Security, hit View update history, hit Uninstall updates and select KB4512941 to rid of it. All you need is either an external or local backup of the operating system and you're set.
