Fixed: Windows 10 Search Crashing


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

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

Exception code: 0xc000027b

Fault offset: 0x000000000016fa94

Faulting process id: 0x3440

Faulting application start time: 0x01d637eba166496b

Faulting application path: C:\WINDOWS\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy\SearchUI.exe

Faulting module path: C:\WINDOWS\SystemApps\Microsoft.Windows.Cortana_cw5n1h2txyewy\SearchUI.exe

Report Id: fed76f9a-f95a-4c79-837f-8f30fa680496

Faulting package full name: Microsoft.Windows.Cortana_1.13.0.18362_neutral_neutral_cw5n1h2txyewy

Faulting package-relative application ID: CortanaUI


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!

Final Thoughts

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.

  1. Worked for me. Tks

  2. Worked,Thank you very much

  3. Mr. Shane Bartholomeusz,

    I’ve been vexxed for days with this recurring problem. Windows Search, Store, and Cartana, and many other Windows functions were severely BORKED. Nothing resolved this problem. I really DID NOT want to re install Windows. Gah!!! I KNEW there was a solution out there.

    Troubleshooting by looking at the Event 1000 in Event Log, the common factor to most “faulting app” errors was “Faulting module name: KERNELBASE.dll”

    All faulting app errors indicated “Exception code: 0x88985004”
    faulting app HxOutlook.exe showed “Exception code: 0xc00000fd”
    faulting app ShellExperienceHost.exe listed Exception code: 0xc000027b

    That’s what led me to your posted solution on page

    I’ve been trying every solution to be found. Yours was the only post that came at the solution along the path of clearing the registry Search settings. It did not resolve it right away. I rebooted and eventually all Search boxes resumed normal function.

    I suspect the root of my problems may have begun by following another solution to debloat the size of Windows.edb, which grew to immense size (30GB?). It appears to swell from doing a lot of PST files work. That should not have mattered, I could be wrong. Anyway …


    You nailed it. Thank you. Gahhh!!! I’m free!!

    You da man.

  4. Awesome in addition I renamed C:\Users\AppData\LocalPackages\Microsoft.Windows.Cortana_cw5n1h2txyewy to C:\Users\AppData\LocalPackages\Microsoft.Windows.Cortana_cw5n1h2txyewyold… this and registry help corrected my issue.

  5. Worked for me, thank you so much. I don’t use the search bar/icon but I heavily rely on winkey then typing (or clicking start than typing) and it would never even appear. If i did it through search bar the search window would appear for 1-2sec but then crash.
