The genuine SearchUI.exe file is a software component of Microsoft Windows Operating System by Microsoft Corporation.
"SearchUI.exe" is a Microsoft process created for Windows 10. It runs as a service under "svchost.exe" in a privileged mode: if stopped by the user it restarts itself in 2 seconds. Its location is "C:\Windows\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy\SearchUI.exe" and it maintains configuration files in "C:\Users\<username>\AppData\Local\Packages", so the Microsoft Cortana search assistant is a Modern UI App. (It has used the same "random" hash string "_cw5n1h2txyewy" since creation.) "SearchUI.exe" is Cortana's main process, activating its Search User Interface. It is tightly integrated with Windows 10 and successive updates keep making it harder to deactivate, which some users want to do because it uploads user data onto Microsoft servers, which the user can supposedly edit or clear, but it can be used to target ads. It prefers Microsoft Edge to implement user browsing requests and Microsoft Bing for search and Microsoft has tried to allow no other browser or search engine with it, causing criticism.
