On Windows 10 Operating system, even when you disable Cortana assistant on Windows settings, the SearchUI.exe or SearchApp.exe will still run in the background. This SearchUI process is now renamed to SearchApp.exe with the latest released versions of Windows 10.
Let’s learn how to disable SearchUI.exe or SearchApp.exe on your Windows Computer.
What is SearchApp.exe?
The SearchApp.exe executable file is related to the search function inside windows 10 and Cortana in previous windows 10 builds.
Even if you open the task manager and end the searchui.exe process on Windows 10, it will automatically restart that service again when you restart your Windows 10 PC.
So how can we stop the searchui.exe or SearchUi.exe from running permanently? Let’s learn how.
Note: I have used the Microsoft Process Explorer application to view running applications with detailed info which you can download here. Here you can see the SearchApp.exe ( Search Application ) on the latest Windows 10 version running permanently.

Thank you, Gowtham, for your tutorial to remove Cortana.
In Windows 10 version 2004 (19041.329, at least), the directory to rename is not
\Microsoft.Windows.Cortana_cw5n1h2txyewy
It is
Microsoft.Windows.Search_cw5n1h2txyewy
to rename with .old.
You can do the rename with the explorer.
At first time before the kill. Il will be rejected (because the task is running), but leave the error window opened.
In CMD, write the taskkill command. Immediately after the Return, click, in the Error window, on Redo to do the rename. It’s necessary to do very quickly because the task SearchApp.exe runs again quickly.
Very wrong. In the 2004 version of Windows, the Cortana was separated from the search (google it for more info). Cortana can be completely uninstalled by powershell with the following command:
Get-AppxPackage -allusers Microsoft.549981C3F5F10 | Remove-AppxPackage
If SearchApp.exe is blocked / removed, search from the start menu will not work in version 2004.
Worked for me after big update in 2020. Copy the kill and rename commands to the clipboard and paste them into the command prompt again and again until the timing is right. Stops the cpu from overheating and makes the laptop fan quiet.
for anyone who disabled it and wants their search bar back, you can do the following:
move %windir%\SystemApps\Microsoft.Windows.Search_cw5n1h2txyewy.old %windir%\SystemApps\Microsoft.Windows.Search_cw5n1h2txyewy
Does it work?
Or no?
Yes it works.
