What is SearchUI.exe and All You Need to Know About It

Permanently Stop SearchUI.exe from Running in Windows 10

Did you know that searchui.exe is the program that runs Windows Cortana? Here’s how to disable this feature temporarily or permanently on your PC…..

What is searchui.exe?

By definition, searchui.exe is an executable background process that allows the PC’s taskbar to function properly.

It used to be part of Cortana, the Windows 10 personal assistant, until the Windows 19 19H1 update in April 2019 when it was removed from Cortana and renamed SearchApp.exe.

The dissociation of searchui.exe (now searchApp.exe) from Cortana has made it considerably low on resource utilization, thus allowing for faster browsing of your PC files, apps, the web, among a host of other computer operations.

It's important to note that searchApp.exe uses other windows processes to manage web searches and file indexing. That makes for very easy file access during searches.

  • Tip! It’s possible to disable Seachui.exe (or SearchApp.exe) temporarily or permanently.

Hiding the search bar utility feature on your PC ensures the Searchui.exe (SearchApp.exe) is paused but enabled. Windows search features will remain active and available; only the search bar will be hidden.

Follow these steps to hide the search bar on Windows 10.

Step 1: Right-click on the search bar (or taskbar) on your PC.

Step 2: On the menu options, hover over the Search option, select Hidden on the right-hand menu.

To enable the Search Bar, right-click on the Task View icon, then on the menu options, select Search then on the next menu, select Show Search Box.

Searchui.exe high CPU usage

A major problem associated with the latest Windows 10 update is Searchui.exe high CPU usage. Sometimes Cortana uses upwards of 45% of a computer’s CPU when the PC is idle. That’s not only disturbing but also worrying, considering that not many people use this Windows 10 feature anyway.

Luckily, fixing this problem is very easy. Follow the steps below to get it done….

Step 1: Open the Windows Run function by pressing Windows key + R. On the Run screen, type Regedit then Enter, or click OK to open the registry editor window.

Windows key + R

Step 2: Next, locate this file path:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search

HKEY

Step 3: Find the “BingSearchEnabled” value, then set the value data to zero, i.e., 0.

Step 4: Restart your PC for the changes to be effected.

You may want to check the CPU usage of Cortana or Searchui.exe via the Task Manager utility to see whether or not the problem was fixed.

  • Tip! If the issue isn’t fixed by setting the value of the “BingSearchEnabled” to 0, consider changing it to 1.

Conclusion

While the Searchui.exe feature makes for easy browsing of the web and searching for files within your PC, the fact is that this Windows 10 utility feature also slows down certain functions of the computer.

With that being said, it is possible to disable Cortana on your PC so that you use a lighter and faster third-party search tool that won’t affect your computer’s performance.
