Hello Sun,
Thank you for your question and for reaching out with your question today.
The error message "Win10 virtual machine cannot start worker process: parameter error (0x80070057) (virtual machine ID)" indicates an issue with starting the virtual machine in Hyper-V. The error code 0x80070057 generally points to an invalid parameter being passed to a function.
To troubleshoot and resolve this issue, you can try the following steps:
- Check Hyper-V Requirements: Ensure that your computer meets all the requirements for running Hyper-V on Windows 11 Insider Preview. Hyper-V requires specific hardware virtualization support (Intel VT-x or AMD-V) to function properly. Check if virtualization support is enabled in your computer's BIOS/UEFI settings.
- Update Hyper-V Integration Services: Ensure that the integration services for the virtual machines are up to date. Integration services improve the interaction between the virtual machines and the host system. To update integration services:
- Go to Hyper-V Manager.
- Select the virtual machine, and in the Actions pane, click "Insert Integration Services Setup Disk" (if available).
- Follow the prompts to update integration services.
- Check for Windows Updates: Make sure your Windows 11 Insider Preview is up to date with the latest updates. Microsoft frequently releases updates that address known issues and improve compatibility.
- Check Virtual Machine Configuration: Review the settings of the virtual machine and ensure that they are correct. Pay special attention to the virtual machine's configuration file (.vmcx) to ensure there are no corruption or invalid settings.
- Try Creating a New Virtual Machine: As a troubleshooting step, try creating a new virtual machine with similar configurations and see if it starts without any issues. If the new virtual machine works fine, it might indicate a problem with the original virtual machine's configuration.
- Remove and Re-add the Virtual Machine: In Hyper-V Manager, try removing the affected virtual machine from the list, and then re-add it. Sometimes, this can resolve configuration-related issues.
- Check for Disk Space: Verify that you have enough free disk space on the host system's drive where the virtual machine files are located.
- Run the System File Checker (SFC) Scan: Run the SFC scan to check and repair any corrupted system files that might be affecting Hyper-V.
- Review Event Logs: Check the Windows Event Viewer for any related error messages or warnings that might provide additional insights into the issue.
If none of the above steps resolve the problem, you may consider reverting to a previous build of Windows 11 Insider Preview if that option is available to you. Alternatively, you can seek assistance from the Windows Insider community forums or Microsoft Support for more specific troubleshooting steps related to your Windows 11 Insider Preview build.
