Windows 11 Search Bar Not Working: 12 Fixes That Actually Work (2026)

When the search bar is unresponsive, the quickest safe reset is restarting Windows Explorer. Explorer owns the taskbar and parts of the Start experience, and when it is stuck, search can appear broken even if the Windows Search engine is fine.

Open Task Manager, locate Windows Explorer, and restart it. After Explorer restarts, wait a few seconds and try typing in the search box again.

A very common Windows 11 symptom is that the search panel opens but stays blank, or you cannot type at all. In many cases, the SearchHost process is stuck. Ending SearchHost forces Windows to restart the search UI cleanly the next time you invoke search. Microsoft Q&A responders frequently recommend this as an effective first-line fix for post-update search breakage.

In Task Manager, go to Details, find SearchHost.exe, end task, then open search again.

If the search panel opens but nothing returns, the engine behind it may be stopped. Open Services and locate Windows Search. If it is stopped, start it. If it is running but suspicious, restart it once. This is safe, reversible, and often enough to bring search back immediately.

After restarting the service, give the system a minute. Then try searching for a built-in app like "cmd" or "settings."

Microsoft increasingly routes troubleshooters through the Get Help experience. The Search and Indexing troubleshooter can detect obvious problems such as stopped services, indexing configuration issues, and certain permission failures. Microsoft documents using Windows troubleshooters via the Get Help app as the supported path.

Open Get Help, search for "Search and Indexing," and run the recommended actions. Then retest the search bar.

This is not intuitive, but it is documented by Microsoft: restarting the Windows Font Cache service can resolve some Windows Search issues. The practical reason is that search UI rendering and certain shell components can behave unpredictably when font cache state is corrupted. Microsoft lists this as Solution 1 in its Windows Search troubleshooting guidance.

Open Services, stop Windows Font Cache Service, start it again, then retry search.

If search works only sometimes, returns partial results, or never finds files that definitely exist, indexing is a prime suspect. Rebuilding the index forces Windows to recreate its database. The important operational point is that rebuilding creates short-term load and takes time. You should rebuild once, then let it complete.

Go to Indexing Options, open Advanced, and select Rebuild. Keep the device awake and on power. Then retest after indexing progress stabilizes.

If servicing components or core files are unhealthy, Windows can stay busy attempting repairs or repeatedly failing. SFC checks protected system files. DISM repairs the OS image that SFC depends on. This is a supported baseline repair and is often the turning point when the slowdown is "sticky" and survives multiple restarts.

Run the commands, let them finish, reboot, and then reassess CPU and disk at idle.

When the search bar breaks after an update, the root cause can be deeper than indexing. If system components are damaged, search can fail in ways that survive service restarts. SFC checks protected system files. DISM repairs the Windows image that SFC relies on. This combination is a safe, supported repair baseline when Windows features misbehave.

Run the commands in an elevated terminal, then reboot once.

If the search UI still fails after service and integrity repairs, the issue can be in the registration state of built-in packages. Re-registering core app packages can restore shell dependencies used by Start and search. This is an escalation step because it changes registrations and can take time to stabilize.

Run the command below as admin, reboot, then test search. If you manage endpoints, validate in a pilot ring first.

Sometimes "search is broken" is actually "Start components are broken." If Start is glitching, search can present blank panels, missing UI, or non-clickable results. Microsoft's Start menu troubleshooting guidance focuses on narrowing down whether a subcomponent is failing and validating deployment and app behavior before moving to heavier repairs.

Test Start itself: open Start, launch Settings, open File Explorer. If multiple shell actions fail, treat this as a Start menu issue, not just a search issue, and keep following the escalation path rather than repeating search-only steps.

If search fails only for one user but works for others on the same machine, profile-level corruption is likely. The cleanest test is to sign in with a new local or domain user and try search immediately. If search works on the new profile, you have strong evidence the issue is within the original user profile state rather than the OS.

In enterprise environments, this is also a useful boundary before you start resetting OS components globally.

When search breaks after a specific update, the safest strategy is often patch-forward rather than chasing fragile workarounds. Install the latest cumulative update available for your channel, reboot, and then reassess. If you already rebuilt the index earlier, do not rebuild again immediately. Verify whether the updated build stabilizes search first, then rebuild once only if symptoms persist.

This is especially relevant if multiple machines break in the same week, which is usually update-correlated behavior rather than isolated corruption.

If the device is still slow, servicing is unreliable, and multiple endpoints show similar failures, an in-place repair upgrade can refresh core Windows components while keeping user data and most apps. This is a practical option when you need a clean servicing state but cannot afford full reimaging.

Treat it as a planned maintenance action. Backup critical data, verify BitLocker recovery keys, and execute during a maintenance window.

If search is still non-functional after service resets, index rebuild, system integrity repair, and profile testing, the machine may have deeper component store or shell corruption. At that point, an in-place repair upgrade is often the cleanest path to restore a supported baseline while preserving files and applications.

Treat this as a planned maintenance action. Confirm backups, verify BitLocker recovery keys, and schedule a maintenance window.
