Recommended fix High confidence

VirtualBox 6.1.40 or later

  1. 1. Back up all important virtual machines and their configurations before proceeding with the update.
  2. 2. Identify the currently installed VirtualBox version by opening VirtualBox and navigating to Help > About VirtualBox, or by running `VBoxManage --version` from the command line.
  3. 3. Stop any running virtual machines and close the VirtualBox application completely.
  4. 4. Download VirtualBox version 6.1.40 (or a later stable version) from the official Oracle VirtualBox download page: https://www.virtualbox.org/wiki/Downloads
  5. 5. Run the installer for your operating system (Windows, macOS, or Linux) and follow the on-screen prompts to install the update.
  6. 6. During installation, ensure the option to install the VirtualBox USB, Networking, and Bridged Networking drivers is selected if prompted.
  7. 7. After installation completes, restart the host computer to ensure all VirtualBox drivers are properly loaded.
  8. 8. Launch VirtualBox and verify the version now shows 6.1.40 or later under Help > About VirtualBox.
Caveat Minor VirtualBox version upgrades typically maintain VM compatibility, but always ensure backups exist before updating; some older VM configurations may require adjustment after major version changes.
