Quick Note: Prerequisites and Initial Checks

Before you begin troubleshooting, ensure your Windows 10 system is up to date. Microsoft regularly releases updates that fix bugs and improve system stability, which may resolve the SearchUI.exe error automatically.

Check your internet connection to download updates if needed.
Restart your computer once before starting the troubleshooting process to refresh system processes.
Close any unnecessary programs to avoid conflicts during fixes.

With these basics covered, you can now proceed to fix the SearchUI.exe not working error.

Step 1: Restart Windows Search Service

The SearchUI.exe process is part of Windows Search. Sometimes, simply restarting the related service can solve temporary glitches.

Press Windows Key + R to open the Run dialog box.
Type services.msc and press Enter to open the Services window.
Scroll down and find Windows Search in the list.
Right-click on Windows Search and select Restart.
If the service is not running, click Start instead.

Restarting this service helps refresh Windows Search and often resolves issues with SearchUI.exe.

Step 2: Run the Search and Indexing Troubleshooter

Windows 10 has a built-in troubleshooter specifically designed to detect and fix search-related problems.

Click on the Start menu and select Settings (gear icon).
Go to Update & Security and then click Troubleshoot in the left panel.
Scroll down and click on Search and Indexing.
Press the Run the troubleshooter button.
Follow the on-screen instructions to detect and fix problems.

This tool performs automated checks and repairs for issues affecting the search functionality.

Step 3: Re-register SearchUI.exe Using PowerShell

If SearchUI.exe files are corrupted or unregistered, re-registering them can help. This process refreshes the system’s connection to the search component.

Click the Start menu, type PowerShell.
Right-click on Windows PowerShell and select Run as administrator.
In the PowerShell window, copy and paste the following command and press Enter:

Get-AppXPackage -Name Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

This command re-registers Cortana and SearchUI components, which are tightly linked.

Step 4: Check for Corrupted System Files

Corrupt or missing system files can cause SearchUI.exe errors. Windows has tools to scan and repair these files automatically.

Open Command Prompt as an administrator (search for cmd, right-click, and select Run as administrator).
Type the following command and press Enter:

sfc /scannow

The System File Checker (SFC) will scan your system and fix any corrupted files. This process may take some time, so be patient.

Step 5: Restart Windows Explorer

Sometimes the graphical interface can cause issues with the search bar. Restarting Windows Explorer can refresh the desktop environment without rebooting.

Press Ctrl + Shift + Esc to open Task Manager.
Find Windows Explorer in the list of processes.
Right-click it and select Restart.

This quick action can resolve minor glitches affecting SearchUI.exe.

Alternative Method: Create a New User Account

If the problem persists, it might be linked to your user profile. Creating a new user account can help identify if the issue is profile-specific.

Open Settings and go to Accounts.
Select Family & other users from the left menu.
Click on Add someone else to this PC.
Follow the prompts to create a new user account.
Log out and sign in with the new account to see if SearchUI.exe works correctly.

If the search works in the new account, consider transferring your files and settings, or continue troubleshooting your original profile.
