yumi.exe

What is yumi.exe?

yumi.exe is the core executable for the YUMI Bootable USB Creator. It coordinates the multi-ISO boot menu builder, detects ISO images, and delegates writing tasks to the USB writer, enabling multi-boot USB creation from a single interface.

YUMI uses yumi.exe to spawn subprocesses for ISO detection, boot sector assembly, and USB writing. It relies on a lightweight GUI and background workers to keep the interface responsive while lengthy operations run in parallel.

Types of YUMI Processes

• Main GUI Process: User interface and orchestrator (1 instance)
• ISO Detection Process: Discovers and validates ISO images to add to the boot menu
• Boot Menu Builder: Constructs the boot menu and integrates ISOs into the USB
• USB Writer Process: Writes boot sectors and ISO data to the target USB drive
• Background Helper: Monitors tasks and handles minor background updates
• Updater/Installer Helper: Manages updates and installer components

Is yumi.exe Safe?

Yes, yumi.exe is safe when it's the legitimate file from YUMI Project downloaded from official sources.

Is yumi.exe a Virus or Malware?

The real yumi.exe is NOT a virus. Malware may mimic names to trick users.

How to Tell if yumi.exe is Legitimate or Malware

1. File Location: Must be in C:\Program Files\Yumi\ or C:\Program Files (x86)\Yumi\. Any yumi.exe elsewhere is suspicious.
2. Digital Signature: Right-click yumi.exe in its folder -> Properties -> Digital Signatures. Should show the publisher as "YUMI Project Team".
3. Resource Usage: Moderate usage during ISO processing; unusual CPU spikes when idle are suspicious.
4. Behavior: Should run only when you start the YUMI GUI or initiate a USB build. Background processes should be limited to updates.

Why Is yumi.exe Running on My PC?

yumi.exe runs when you start YUMI to build or manage a multi-ISO USB, or when the background updater checks for new components and templates.

Reasons it's running:

• Active USB Creation Session: You have started a multi-ISO USB build; each task spawns subprocesses for speed.
• Background ISO Scanning: YUMI periodically scans for newly added ISOs or templates to update the menu.
• GUI Interaction: The main GUI keeps the state synchronized with disk writes and USB operations.
• Startup or Startup Entries: YUMI may add a startup entry to check for updates or ready-to-use USBs.
• Background Updates: Updater components fetch templates and boot files to keep menus current.

Can I Disable or Remove yumi.exe?

Yes, you can disable yumi.exe. It's safe to close the YUMI GUI when not in use, and you can uninstall YUMI completely if you prefer a different tool.

How to Stop yumi.exe

• Close YUMI GUI: Click the close button or choose Exit to terminate the GUI.
• End ISO Detection: In the GUI, stop the current build; or use the Task Manager to end yumi.exe.
• Disable Startup: Open Task Manager → Startup tab → Disable YUMI.
• Prevent Background Updates: Within YUMI settings, turn off automatic updates.
• Remove USB Build Tasks: Delete or deselect ISOs and templates from your YUMI catalog.

How to Uninstall YUMI

• ✔ Windows Settings → Apps → Apps & features → YUMI → Uninstall
• ✔ Control Panel → Programs → Uninstall a program → YUMI → Uninstall
• ✔ Delete remaining YUMI folders in C:\Program Files\Yumi and AppData if present

Common Problems: High CPU or Memory Usage

If yumi.exe is consuming excessive resources during builds or ISO detection:

Common Causes & Solutions

• Too Many ISOs in catalog: Remove unnecessary ISOs or move them to a dedicated folder; reduce catalog size.
• Background Update Checks: Disable auto-update checks in settings or schedule them manually.
• Resource-Heavy ISOs: Some ISOs are large; consider using smaller test images during development.
• Slow USB Drive: Use a faster USB 3.0 drive and ensure proper USB port.
• Antivirus Scanning: Temporarily disable real-time scanning for YUMI folder during writes; re-enable afterward.
• Outdated YUMI Version: Update YUMI to the latest version from the official site.
