Is it a Virus?
✔ NO - Safe
Must be in C:\Program Files\VirtualTech\VirtualMachineUpdater\Updater.exe or C:\Program Files (x86)\VirtualTech\VirtualMachineUpdater\Updater.exe
Warning
Many updater processes normal
Each update task may spawn sub-processes for host hypervisor components
Can I Disable?
✔ YES
You can disable automatic updates; however, keep in mind this may affect VM performance and security
What is virtual-machine-updater.exe?
virtual-machine-updater.exe is the updater service for virtualization software. It checks for patches to the hypervisor, VM tools, and guest additions across VMware, VirtualBox, and other platforms, then applies them as configured.
It runs as a background service with elevated rights when needed, validates signatures, and coordinates with host components to minimize VM disruption during updates.
Quick Fact: Virtualization update services help prevent VMware Tools and Guest Additions mismatches that can cause VM instability.
Types of Updater Processes
- Service Process: Main Windows service that schedules and applies updates (1 instance)
- Component Updater: Updater for specific hypervisor components (VMware, VirtualBox)
- Tool Installer: Installs or repairs VM Tools/Guest Additions inside VMs
- Signature Verifier: Verifies update packages before applying
- Logger: Writes to Event Viewer and log files
Is virtual-machine-updater.exe Safe?
Yes, virtual-machine-updater.exe is safe when sourced from the official VirtualTech updater channel and installed from the vendor’s distribution.
Is virtual-machine-updater.exe a Virus or Malware?
The real updater is not a virus. Malware may imitate names; verify the file path and digital signature.
How to Tell if virtual-machine-updater.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\VirtualTech\VirtualMachineUpdater\Updater.exe or C:\Program Files (x86)\VirtualTech\VirtualMachineUpdater\Updater.exe. Any other path is suspicious.
- Digital Signature:: Right-click Updater.exe → Properties → Digital Signatures. Should show "VirtualTech Ltd." as the signer.
- Resource Usage:: Normal usage is 1-8% CPU and 40-120 MB memory. Persistent high usage or spikes when idle is suspicious.
- Behavior:: Updater should run on demand or on a scheduled basis, not repeatedly after a clean boot without updates.
Red Flags: If Updater.exe appears outside the official install path, lacks a valid signature, or consistently uses resources without updates available, scan with antivirus and verify with vendor support.
Why Is virtual-machine-updater Running on My PC?
The updater runs to keep virtualization software current and secure. It may operate during idle times or when the host requests maintenance tasks.
Reasons it's running:
- Active Update Checks: The service queries vendor servers for patches and verifies compatibility before applying them.
- Background VM Tools Updates: Guest Additions and VMware Tools are updated automatically to maintain VM functionality.
- Scheduled Maintenance: A scheduled job runs during off-peak hours to minimize VM disruption.
- Host Component Dependencies: Updates may depend on host hypervisor components already installed or updated.
- Startup and Background Tasks: The service may start at Windows boot and run in the background to monitor for updates.
Can I Disable or Remove virtual-machine-updater?
Yes, you can disable the updater. Stopping it won't remove virtualization platforms, but you may miss important patches.
How to Stop virtual-machine-updater
- End the Service: Open Services (services.msc), locate VirtualMachineUpdater, and click Stop.
- Disable Startup: In Services, set Startup type to Disabled to prevent auto-start.
- Prevent Background Execution: Open Task Scheduler (taskschd.msc) and disable any updater tasks.
- Network Updates: If you use virtualization products, ensure no dependencies rely on the updater for critical fixes.
- Security Considerations: Keeping updater disabled long-term can expose VMs to outdated drivers and tools.
How to Uninstall Virtual Machine Updater
- ✔ Windows Settings → Apps → Apps & Features → VirtualTech VirtualMachineUpdater → Uninstall
- ✔ Control Panel → Programs → Uninstall a program → VirtualTech VirtualMachineUpdater → Uninstall
- ✔ Restart the computer after uninstall
Common Problems: Updater Performance and Reliability
If virtual-machine-updater is misbehaving or slow:
Common Causes & Solutions
- Network or firewall blocks: Ensure outbound traffic to vendor update servers is allowed on ports 443 and 80. Check proxy settings if behind a corporate firewall.
- Stalled update checks: Restart the updater service and verify the system clock is correct. Check logs for update-server errors.
- Conflicting virtualization tools: Temporarily disable other updater services that manage similar components to avoid conflicts.
- Corrupted update packages: Clear updater cache and re-download updates from the vendor site.
- Insufficient permissions: Run updater with administrative privileges or adjust permissions for the updater folder.
- Outdated updater: Update the updater itself from the vendor distribution channel to ensure compatibility with hypervisor versions.
Quick Fixes:
1. Quick Fixes:
2. 1. Open Services and restart VirtualMachineUpdater
3. Check for available updates manually in the updater UI
4. Ensure network access to vendor servers
5. Clear updater cache and retry
6. Verify the system date/time is correct
Frequently Asked Questions
