What is Unity Hub.exe?

unityhub.exe is the executable for Unity Hub, the central launcher used to install, organize, and launch multiple Unity Editor versions and modules. It coordinates editor installations, license management, account sign‑in, project associations, and updater services, while communicating with Unity services in the background.

Unity Hub runs as a multi‑process launcher: the main UI, background updater, and editor installers run separately to keep the launcher responsive. It caches metadata, tracks installed editors, and validates licenses via Unity services.

Quick Fact: Unity Hub centralizes editor management, so you can switch between versions without reinstalling editors.

Types of Unity Hub Processes

Hub UI Process: Main window and user interactions
Updater Process: Checks for Unity Hub and editor updates
Editor Installer: Installs or repairs Unity Editor versions
License/Account Service: Handles sign‑in and license validation
Background Sync: Syncs settings and project data with Unity services

Is unityhub.exe Safe?

Yes, unityhub.exe is safe when it's the legitimate file from Unity Technologies downloaded from official sources (unity.com or Unity Hub installer).

Is unityhub.exe a Virus or Malware?

The real unityhub.exe is NOT a virus. However, malware occasionally masquerades with similar names to mislead users.

How to Tell if unityhub.exe is Legitimate or Malware

File Location: Must be in C:\Program Files\Unity Hub\Unity Hub.exe or C:\Program Files (x86)\Unity Hub\Unity Hub.exe. Other locations are suspicious.
Digital Signature: Right-click Unity Hub.exe -> Properties -> Digital Signatures. Should show "Unity Technologies" as the publisher.
Resource Usage: Normal usage is typically 1-12% CPU and 100-400 MB memory when idle; spikes occur during updates.
Behavior: Unity Hub should launch only when you start it or when an editor is installing. Constant background activity when idle is suspicious.

Red Flags: If unityhub.exe is found outside the Unity Hub directory, lacks a valid digital signature, or runs when you did not start Unity Hub, scan with antivirus and verify with Unity Support.

Why Is unityhub.exe Running on My PC?

Unity Hub runs to provide version management, launcher services, and editor installations. It may stay active while you manage or update editors, sign in to your Unity account, or check for updates.

Reasons it's running:

Active Hub Use: You are using Unity Hub to install, launch, or manage Unity Editor versions; the hub runs to coordinate tasks.
Background Updater: The updater service runs to check for Hub or editor updates and apply them silently.
Startup Program: Unity Hub may be configured to launch at Windows startup to provide quick editor access.
License and Sign-In: Sign-in or license validation tasks run in the background to verify your Unity license.
Editor Installations: Installing or repairing Unity Editor versions via the Hub launches background installers.

Can I Disable or Remove unityhub.exe?

Yes, you can disable Unity Hub. It is safe to close the UI or prevent startup if you do not use Unity Hub, and you can uninstall it if you prefer another workflow.

How to Stop unityhub.exe

Close Hub UI: Click the X or choose Sign Out to gracefully close Unity Hub
Quit All Editor Installations: Ensure no active editor installation or update is running in the Hub
Disable Startup: Task Manager > Startup tab > Disable Unity Hub
Stop Background Sync: In Unity Hub settings, disable background sync and updater if available
Uninstall: Windows Settings > Apps > Unity Hub > Uninstall

How to Uninstall Unity Hub

✔ Windows Settings → Apps → Apps & Features → Unity Hub → Uninstall
✔ Control Panel → Programs → Uninstall a program → Unity Hub → Uninstall
