What is SearchApp.exe (SearchUI.exe)? How To Remove?

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 process is now renamed to SearchApp.exe with the latest released versions of Windows10.

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.

How to disable SearchUI.exe permanently

In older Windows versions you will see SearchUI.exe running instead of the SearchApp.exe. Follow the steps below if you wanted to disable SearchUI.exe.

  1. Open command prompt by searching CMD or Open Run command by pressing the Windows key + R button and type in cmd.exe and hit enter button.
  2. Right-click and select Run as Administrator option on your command prompt window on your taskbar. Click on Yes option on the prompt window.
  3. To disable the searchui.exe from command prompt enter the below code
  4. C:\WINDOWS\System32> taskkill /f /im SearchUI.exe
  5. And hit Enter key. Now it will kill the task. Now in order to kill this task permanently, we need to rename it to something else and move it to some other directory
  6. We will append .old to the original file and move it. To do this enter the below command as a single line and hit enter.
  7. C:\WINDOWS\System32> move %windir%\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy %windir%\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy.old
  8. Now the file will be moved.

Update: On Windows 10 Version 2004, the SeachApp.exe is merged with the Windows Search Function so if you delete or remove it the search function might not work. So do it with caution or a restore point.

How To Stop SearchApp.exe Permanently

1. Run the following commands on the Command prompt window run as admin.

C:\WINDOWS\System32> taskkill /f /im SearchApp.exe

2. Then type the following commands to move the file.

For older Windows Version before Windows 10 version 2004 (19041.329) you have to move the Cortana folder instead.

C:\WINDOWS\System32> move %windir%\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy %windir%\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy.old

3. For newer Windows 10 versions above Windows 10 version 2004 (19041.329) use the following commands instead

C:\WINDOWS\System32> move %windir%\SystemApps\Microsoft.Windows.Search_cw5n1h2txyewy %windir%\SystemApps\Microsoft.Windows.Search_cw5n1h2txyewy.old

This will rename the file as shown below in the screenshot.

4. Now the Cortana SearchUI.exe or the SearchApp.exe task will not run again.

    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.
