# ShellHost.exe

Windows Process: Microsoft Corporation

Also called shellhost, windows shell host

Windows, System Component

Windows Shell Host. Current Windows uses it for some shell surfaces that are not the full explorer.exe desktop.

## What you need to know

This is a shell host helper. explorer.exe still owns the taskbar.

ShellHost.exe is a Windows shell host in System32. It is not File Explorer and it is not sihost.exe (flyouts). Ending it should not be your first taskbar fix.

- **Safe?**: Yes, in System32

  **Same as explorer?**: No. Explorer is the desktop shell

  **Should I end it?**: A shell surface may close

Feex says

If the taskbar is gone, I restart explorer.exe first. ShellHost is a different host. I would not delete System32\ShellHost.exe to recover icons.

## What is ShellHost.exe?

ShellHost.exe is Windows Shell Host. Microsoft uses extra hosts so a crashing surface does not always take the whole desktop.

## What does it do?

It hosts shell UI that is not a folder window. Folder windows stay in explorer.exe. Flyouts often stay in sihost.exe.

## Why is it running?

The interactive session started a shell surface that this host owns. A missing ShellHost with a working taskbar can be normal if that surface is idle.

## Is it safe?

Usually safe

System32 ShellHost signed by Microsoft is the host. A ShellHost.exe in a theme pack is not.

A legitimate copy normally runs from:

`C:\Windows\System32\ShellHost.exe`

- Not explorer.exe
- Not sihost.exe
- Publisher: Microsoft Corporation

## Can I end it?

May close a shell surface

Ending ShellHost.exe can close the surface it was hosting. Restart Explorer if the taskbar died. Do not loop-kill ShellHost as a tune-up.

## Can I remove it?

No

Do not delete ShellHost.exe. Repair the shell with SFC after you confirm corruption, not with a downloaded host.

## Should it start with Windows?

The session starts it as needed. It is not a vendor Startup leftover.

## Normal resource behavior

These are contextual labels, not universal averages.

- **CPU**: Low unless a shell surface is animating badly

  **Memory**: Small

  **Disk**: Low

  **Network**: None by itself

## File information

| Executable name        | ShellHost.exe                     |
| ---------------------- | --------------------------------- |
| Common legitimate path | C:\Windows\System32\ShellHost.exe |
| Publisher              | Microsoft Corporation             |
| Signature expectation  | Signed by Microsoft Windows       |

## Common problems

### People apply Explorer restart tips to ShellHost

Wrong host. Restart explorer.exe for a missing taskbar.

### High CPU with a broken shell extension

Test a clean boot. Extensions still load through the shell family.

## Troubleshooting

Diagnose before you change anything destructive.

### Restart Explorer first for taskbar issues

Then sihost for stuck volume HUDs. ShellHost is a later guess.

### Open file location

System32 only.
