Problem

In this post I'll show you how to fix an issue with Windows 10 Search disappearing.

While trying to use the Windows 10 Search I noticed that after I entered a few characters the Search Box would crash and clear out the text I had entered. No search results were being displayed.

Upon further investigation I found the following error message logged in the Windows Event Viewer:

Faulting application name: SearchUI.exe, version: 10.0.18362.752, time stamp: 0x5e7049d9

Solution

It turns out that the Registry entries for Windows Search had become corrupt during a recent Windows Update.

The solution is to manually delete the corrupt Registry entries. Windows Search will then automatically recreate them.

Here is the step-by-step process:

1. Open the Registry Editor. You can do this by pressing the WIN + R keys, enter text “regedit” and press ENTER to launch the Registry Editor.

2. Navigate to Registry entry Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search

Tip: copy and paste the above address into the address bar.

3. Backup Registry entries under the “Search” node (via FILE > EXPORT).

4. Delete the “Search” Registry key including all sub-keys. Right click the “Search” key and click DELETE.

5. Use the Windows Search box several times. This will trigger the Windows Search utility to recreate the Registry keys we just deleted.

In my case, after around 5 minutes the Windows Search function started working again yay!

I hope this fix has solved the issue for you. If you find any other solutions that have worked, feel free to post them in the comments below to help others.
