# hostname.exe

Windows Process: Microsoft Corporation

Also called hostname, computer name command

Windows, System Component

Prints the computer name to the console, then exits. It is a command, not a service and not a background host.

## What you need to know

hostname prints the name, it is not a service.

hostname.exe writes the DNS hostname to stdout. Scripts and Command Prompt call it. It is not Computer Browser, not Dnscache, and not a tray app.

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

  **Is it a service?**: No. It prints and exits

  **Should it stay running?**: No. A stuck copy is unusual

Feex says

If hostname flashed in Task Manager, I treat that as a script asking the PC name. I do not hunt a Hostname service to disable.

## What is hostname.exe?

hostname.exe prints the computer name. It is not a service. The binary is a short-lived Windows command in System32.

## What does it do?

It reads the hostname and writes one line. It does not rename the PC. That is Settings or Rename-Computer. It does not stay resident.

## Why is it running?

A script, an installer, or you typed hostname. If it is still running minutes later, something launched it in a loop or the name is a fake path.

## Is it safe?

Usually safe

System32 hostname.exe is the command. A hostname.exe in a toolkit zip is not that command.

A legitimate copy normally runs from:

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

- CLI only
- Not a service
- Expected to exit immediately

## Can I end it?

Usually already gone

Ending hostname.exe only matters if a loop keeps spawning it. Stopping a service named something else will not cancel this command.

## Can I remove it?

No

Do not delete hostname.exe. Scripts that print the computer name will fail. Renaming the PC is a Settings change.

## Should it start with Windows?

A script may call it at logon. It should not be a Startup Apps row of its own.

## Normal resource behavior

These are contextual labels, not universal averages.

- **CPU**: Negligible

  **Memory**: Tiny, then gone

  **Disk**: None

  **Network**: None. It prints a local name

## Common problems

### People look for a Hostname service

There is not one for this exe. Computer Name lives in Settings > System > About.

### Loop in a broken logon script

The parent is cmd.exe or powershell.exe. Fix the script. Do not delete System32\hostname.exe.

## Troubleshooting

Diagnose before you change anything destructive.

### See the parent process

Command Prompt or PowerShell usually started it. That parent is the story.

### Open file location

System32 only. Any other folder is a different program.
