SearchUI.exe dey live inside the Cortana SystemApp. Current Windows 11 usually dey show SearchHost.exe. To end SearchUI.exe no go stop file indexing.

- **E safe?**: Check the running file path, signature, and publisher. Name alone no fit confirm say e safe.

  **Still dey on Windows 11?**: Plenti PCs don move go SearchHost

  **I suppose end am?**: Search flyout dey close

Feex tok say

If I dey on Windows 10 and SearchUI na the hot name, I dey treat am as the flyout. I still dey leave WSearch make e run unless the catalog itself na the problem.

SearchUI.exe na the older Cortana / Search UI executable. Microsoft later split or rename hosts to SearchApp.exe and SearchHost.exe.

## Wetin e dey do?

E dey draw the Search pane on top Windows 10-era builds. E no dey crawl NTFS. SearchProtocolHost.exe and SearchFilterHost.exe dey do dat work for the indexer.

## Wetin make am dey run?

You open Search on top build wey still dey use this package, or Foxhole see Windows 10 PC. Make e no dey on Windows 11 na wetin dem often expect.

## Inspect the running instance

Inside Windows PowerShell, this read-only query show matching process IDs, creation times and executable paths on this PC. (pcm)

`Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'SearchUI.exe' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List`

No result or a path we no fit access is inconclusive. Protected processes fit restrict access, and process IDs fit be reused. Keep personal paths local. (pcm)

Use the [file-identity guide](https://feex.it/wiki/l/pcm/software/system/verify-executable-path-signature/) to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)

## E dey safe?

Check dis running file

The Cortana or Search SystemApp binary na Microsoft own. SearchUI.exe inside download pack no be am.

Compare the recorded location with the actual file. A familiar folder alone no fit establish identity. (pcm)

`C:\Windows\SystemApps\Microsoft.Windows.Cortana_*\SearchUI.exe`

- Windows 10-era host
- Later: SearchApp.exe / SearchHost.exe
- Indexer remain SearchIndexer.exe

## I fit end am?

E dey close dat Search UI

To end SearchUI.exe dey close the pane. Indexing dey continue. The host fit return on the next Search key.

## I fit comot am?

No

No delete the Cortana package to "debloat" Search. Use Search settings. SearchHost.exe na the usual host on top current Windows 11.

## E suppose start with Windows?

Search / Cortana dey start am. No be vendor Startup leftover.
