Windows 11 Taskbar Search Not Working After KB5063060: How to Fix It

Press the Windows key, type something, and instead of results you get an empty box with a thin blue line scrolling across the top. Nothing loads. Nothing happens. If this started after installing KB5063060 or one of the cumulative updates released in mid-2026, you're dealing with a known regression in how Windows 11 loads the search panel, not a hardware problem on your PC.

Here's what's happening under the hood and the fixes bringing search back.

Why Did Windows 11 Search Stop Working After KB5063060?

KB5063060 changed how the search panel renders results, and on many systems this change causes the SearchHost.exe process to hang while pulling data from the search index. The panel opens, starts loading, and never finishes. The blue line at the top keeps scrolling because Windows still thinks it's waiting on a response.

Three things typically cause this after the update:

• A corrupted or partially rebuilt search index. The index powering search got interrupted during the update installation, so queries against it never return.
• A stuck SearchHost.exe or StartMenuExperienceHost.exe process. These two processes handle the taskbar search UI, and one of them gets stuck in a bad state when an update installs while apps stay running in the background.
• A damaged user profile. Less common, but a corrupted profile breaks the search UI specifically while leaving the rest of Windows working fine.

You don't have to guess which one applies to your machine. Work through the fixes below in order, starting with the fastest and moving to the more thorough ones only if needed.

How Do I Restart the Search Process Without Restarting My PC?

Open Task Manager, find SearchHost.exe under Processes, and end the task. Windows relaunches it automatically within a few seconds, and search often works again right away.

Here's the exact sequence:

1. Right-click the Start button, or press Ctrl+Shift+Esc, to open Task Manager.
2. Click the Processes tab.
3. Scroll down to Search or look for SearchHost.exe directly.
4. Right-click it and select End task.
5. Wait 5 to 10 seconds, then click the search icon on the taskbar again.

If SearchHost.exe restarts and the panel still shows the blank blue-line screen, repeat the steps for StartMenuExperienceHost.exe, listed right below it in Task Manager. Between the two, this clears the stuck process in most cases reported since the update went out.

This fix doesn't stick for everyone. If the blank panel returns after a reboot, move on to rebuilding the index.

How Do I Rebuild the Windows Search Index?

Rebuilding the index forces Windows to scan and re-catalog every indexed folder from scratch, clearing out whatever got corrupted during the update. It takes time, but it's the fix resolving this permanently for most people who try it.

Steps:

1. Open Settings.
2. Go to Privacy & security, then Searching Windows.
3. Under Find My Files, confirm Classic or Enhanced mode is selected. Either works for this fix.
4. Scroll down to Related settings and click Advanced indexing settings.
5. In the window opening next, click Advanced.
6. Go to the Index Settings tab and click Rebuild.
7. Confirm the prompt warning about the indexing time.

Indexing runs in the background. On a laptop with a few hundred gigabytes of files, expect anywhere from 20 minutes to a few hours depending on drive speed and how many locations you have indexed. Search sometimes works partially while the rebuild finishes, or stays blank until it completes fully. Leave the PC on and plugged in until the process wraps up.

How Do I Restart the Windows Search Service?

Restarting the Windows Search service through the Services app resets the background service feeding the index, separate from the SearchHost.exe UI process. Try this if ending the task and rebuilding the index both failed to fix things.

1. Press Windows key + R, type services.msc, and press Enter.
2. Scroll down to Windows Search.
3. Right-click it and select Restart. If Restart is grayed out, select Start instead.
4. Close Services and test the taskbar search again.

If the service won't restart or throws an error, right-click Windows Search, choose Properties, and check whether Startup type is set to Automatic. A previous troubleshooting attempt or a third-party tuning tool sometimes switches it to Manual or Disabled, and this stops the index from updating even after a reboot.

How Do I Run System File Checker to Fix Search?

System File Checker scans core Windows files for corruption and replaces anything damaged, fixing search when the root problem traces back to a broken system file rather than the index alone. Run it if the service restart didn't help.

1. Open the Start menu, type cmd, right-click Command Prompt, and select Run as administrator.
2. Type sfc /scannow and press Enter.
3. Let the scan finish. It usually takes 10 to 15 minutes.
4. If it reports repairs made, restart your PC and test search again.

If SFC reports errors it wasn't able to fix, run DISM /Online /Cleanup-Image /RestoreHealth first, then run sfc /scannow a second time. DISM repairs the underlying Windows image SFC pulls replacement files from, so a failed SFC scan often succeeds on the next pass once DISM finishes.

What If Nothing Fixes Search on My Windows 11 PC?

If you've ended the process, rebuilt the index, restarted the service, and run SFC and DISM with no change, the problem sits with your user profile more than with Windows itself.

Create a new local user account through Settings, then Accounts, then Other users, then Add account. Sign into the new account and test search there. If search works on the new profile, your original profile has a corrupted setting somewhere, one none of the standard repairs reach. Move your files to the new profile and retire the old one, or reach out to Microsoft Support if you'd rather keep your existing profile intact and want help diagnosing it directly.

Before going this route, check for a newer cumulative update under Settings, then Windows Update. Microsoft has shipped follow-up patches addressing earlier search regressions before, and installing the latest one sometimes solves the problem without any manual steps at all.

Does This Only Affect Certain Windows 11 Versions?

Reports of the blank search panel span both 23H2 and 24H2 installations, so the version you're running doesn't determine whether you hit this bug. What matters is whether KB5063060 or one of the follow-up cumulative updates installed on your machine.

Check your update history under Settings, then Windows Update, then Update history, to confirm which patches you have. If you installed anything from July or August 2026 shortly before search stopped working, this update is the likely trigger, and the fixes above apply regardless of which feature version of Windows 11 you're on. Enterprise and Education editions on delayed update rings have reported the same issue once the patch reaches them, so a slower rollout schedule delays the problem rather than avoiding it.

Key Takeaways

• KB5063060 and related mid-2026 updates broke taskbar search for many Windows 11 users, showing a blank panel with a blue loading line instead of results.
• End SearchHost.exe, and StartMenuExperienceHost.exe if needed, in Task Manager first. It's the fastest fix and resolves things immediately on some systems.
• Rebuilding the search index through Settings, Privacy & security, Searching Windows fixes it permanently for most people, though it takes time to finish.
• Restarting the Windows Search service in services.msc and running sfc /scannow catch cases the index rebuild doesn't.
• A new local user profile isolates whether the problem sits with your account specifically when none of the other fixes work.
