When Microsoft launched Windows 10, everyone was excited about the new features, including Siri Killer Cortana. But Cortana did not turn out to be what people expected from all this hype. It uses too much CPU power and interferes with the daily activities of the user. Even when you disable Cortana in the configuration, it continues to run “SearchUI.exe” in the background, further reducing the available RAM in the system. And they designed the process so that it never stops and automatically restarts, even when trying to remove it using the Windows Task Manager or Process Explorer.

But there is a way to stop and prevent SearchUI.exe from running on Windows 10. If you do not really need Cortana and the various processes running on your system all the time, you can use this method to disable SearchUI. . .exe also:

Methods to stop searchui.exe

Method 1:

Start the command prompt. To do this, press the Win + X key combination, then choose Command Prompt (Admin) from the on-screen menu.
In the command window, type these commands one by one, pressing Enter after each one (and be very quick):


taskkill / f / im SearchUI.exe
move% windir% \ systemApps \ Microsoft.Windows.Cortana_cw5n1h2txyewy% windir% \ systemApps \ Microsoft.Windows.Cortana_cw5n1h2txyewy.000
If the commands fail simultaneously, repeat them until the directory is moved correctly.

Method 2:

1.Open the Windows Registry Editor. You can get there by typing “reged” into the search box. Keep in mind that editing the registry can be risky so we recommend making sure that you back up your system

2. Navigate to the Registry key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

3. Create a new key named “Windows Search”  Right-click and select New->Key then renaming the folder it creates to “Windows Search.” If Windows Search already exists, navigate to it

4.Create a new DWORD (32-bit) Value named “AllowCortana” in the Windows Search Key. You can do this by right-clicking and selecting New->DWORD (32-bit) value, then renaming it to “AllowCortana”.

 5. Reboot your computer. You should see a “Type here to search” box where Cortana’s box used to be. You can use this box to search your  files and apps, as well as the web (via Bing)
