SearchUI.exe goes from Suspended to Running to Not Responding
The cause could either be missing system files or an issue with the Cortana application itself. In case you are facing this problem, try rebooting the system and check if it helps. If not, proceed with the following solutions:
1] Run the Search and Indexing Troubleshooter
Click on the Start button and select Settings > Updates and Security > Troubleshoot. Select the Search and Indexing Troubleshooter from the list and run it. Restart the system once done. Windows 7/8 users may download the Windows Search Troubleshooter and run it.
2] Run the DISM Tool
The DISM tool repairs a potentially corrupted system image. You could consider running it to fix your problem.
3] Restart the Cortana process in the Task Manager
Press CTRL + ALT + DEL to open the Security Options window. Select and open Task Manager from the list. Locate the Cortana process, right-click on it and select End Task. The Cortana process will restart on its own and re-initialize itself.
4] Reinstall Cortana
If nothing else works, you could consider reinstalling Cortana itself. Right-click on the Start button and select Windows PowerShell (Admin). Type the following command in the elevated PowerShell window and press Enter to execute it: Restart the system.
5] Troubleshoot in Clean Boot State
You can troubleshoot further manually by performing a Clean Boot. A Clean Boot starts a system with minimal drivers and startup programs. When you start the computer in clean boot, the computer starts by using a pre-selected minimal set of drivers and startup programs, and because the computer starts with a minimal set of drivers, some programs may not work as you expected. Clean-boot troubleshooting is designed to isolate a performance problem. To perform clean-boot troubleshooting, you must disable or enable one process at a time, and then restart the computer after each action. If the problem goes away, you know that it was the last process which was creating the problem. All the best!
