using search bar in file explorer locks up explorer (searchapp.exe fault) windows 10

I had a machine that kept crashing when you put anything in the search bar in file explorer. After digging through the event viewer I found a couple errors related to explorer and searchapp.exe.

The program explorer.exe version 10.0.19041.3031 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.

After a little digging I found this post on tenforums because of finding the searchapp.exe crash logs, not from searching “file explorer crashes when using search” which was my initial approach. So hopefully this helps someone who’s having difficulty fixing this issue, and trying my way first.

  1. 1.
    1. Click/tap on the Download button below to download the file below.
    The downloadble .reg file below will delete the registry key below.
    2. Save the .reg file to your desktop.
    3. Double click/tap on the downloaded .reg file to merge it.
    4. When prompted, click/tap on RunYes (UAC), Yes, and OK to approve the merge.
    5. restart pc to apply
    6. You can now delete the downloaded .reg file if you like.
  2. 2.
    1 .Click/tap on the Download button below to download the .bat file below.
    Contents of the .bat file for reference:
    @echo off
    REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell\StateStore" /V ResetCache /T REG_DWORD /D 1 /F
    taskkill /f /im explorer.exe
    start explorer.exe
    2. Save the .bat file to your desktop. 3. Unblock the .bat file. 4. Run the .bat file. 5. You will now notice your screen flicker as a command prompt quickly opens and closes to run the command to reset the live tile cache, then restarts the explorer process to apply.

    As the original post on tenforums mentioned, don’t forget to restart the computer after applying the fixes. Again, credit to the guys over on tenforums for coming up with the fix, files linked here  just in case the posts disappear.

    Thanks for reading,
