Windows 11 Search Bar Not Working After KB5074109? (Can’t Type / Frozen) — Step-by-Step Fix

If Windows 11 Search suddenly won’t accept typing, feels frozen, or Start-menu search does nothing right after the January 13, 2026 cumulative update (KB5074109), you’re not alone.
In most cases, you can fix it without reinstalling Windows—you just need to hit the right component in the right order.

If your whole system feels sluggish (not just Search), check RAM first—one heavy browser process can make the taskbar feel “dead.”

If you noticed Windows Update hanging for a long time before this started, it may have installed incorrectly.

Step 0) Split the symptom (so you don’t fix the wrong thing)

A) You click Search but no cursor appears / you can’t type at all

Usually an input service (TSF/CTF) or Search process glitch. Start at Step 1–4.

B) You can type, but results are missing / wrong / incomplete

Usually indexing/settings. Start at Step 5–6.

C) It started right after KB5074109

Run Step 4 (Reset Windows Search script) earlier than usual.


Step 1) Quick refresh (the “stupid simple” fix)

  1. Restart your PC

  2. If you can’t restart, restart Windows Explorer:

    • Path: Task Manager → Windows ExplorerRestart

This clears stuck taskbar/UI states that can block typing into Search.


Step 2) Restart the Search process (fast “unstick”)

  • Path: Task Manager → Details → SearchHost.exeEnd task
    Windows will relaunch it automatically.

If typing immediately works again, it was a stuck Search process.


Step 2.5) ⭐ Pro Tip: Can’t type at all? Run ctfmon.exe (Text Input “CTFMon” trick)

If you click the search bar but no cursor shows up, the Text Services Framework (TSF) input layer may be stuck—ctfmon.exe is part of that system.

  1. Press Win + R

  2. Type: ctfmon.exe → Enter

  3. Try typing in the Search bar immediately

If it suddenly works, it was a keyboard/input service glitch, not “broken Search.”


Step 3) Make sure the Windows Search service is running

  • Path: Win + R → services.mscWindows Search

    • Status: Running (restart if needed)


Step 4) Run Microsoft’s official “Reset Windows Search” script ⭐ (biggest hammer that’s still safe)

Microsoft provides ResetWindowsSearchBox.ps1 to reset Windows Search components.

How to run it (official + clean):

  1. Download: [Microsoft: Reset Windows Search PowerShell script]

  2. Right-click the file → Run with PowerShell (Admin permissions required)

  3. Follow prompts until you see “Done”

  4. Restart your PC

This is one of the most consistently recommended steps when Search breaks after updates.


Step 5) Run the “Search and Indexing” troubleshooter

  • Path (Windows 11): Settings → System → Troubleshoot → Other troubleshooters → Search and Indexing → Run

Use this when Search works but behaves weird (missing apps/files).


Step 6) Rebuild the Search index (only if results are missing)

  • Path: Settings → Privacy & security → Searching Windows → Advanced indexing optionsRebuild

This can take time depending on how much you have on disk.


Step 7) Confirm KB5074109 + rollback only if you must

  • Path: Settings → Windows Update → Update history

If Search is mission-critical and nothing above works, uninstall the most recent cumulative update temporarily (then pause updates briefly).
KB5074109 is the January 13, 2026 cumulative update for Windows 11 24H2/25H2.


Step 8) Advanced: Disable Bing “Web Search” results to make Search feel instant 🚀

Sometimes Search feels frozen because it’s trying to pull web results (Bing/online suggestions) when you just want local apps/settings. Disabling web suggestions can reduce lag and clutter.

Option A (lighter, Settings): turn off Search highlights

  • Path: Settings → Privacy & security → Search permissions → Search highlights → Off
    This won’t fully remove web integration in every build, but it can reduce the “busy” feeling.

Option B (stronger, Advanced): Registry tweak (Windows 11 Home + Pro)

⚠️ Editing the registry is powerful—do it only if you’re comfortable. Create a restore point first.

Registry method (DisableSearchBoxSuggestions):

  1. Win + R → regedit

  2. Go to:
    HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows

  3. Create a key (folder) named: Explorer (if it doesn’t exist)

  4. Inside Explorer, create DWORD (32-bit): DisableSearchBoxSuggestions

  5. Set value to: 1

  6. Restart the PC

To undo: delete that DWORD or set it back to 0.
