Windows Sandbox not enble — by Eric O'Malley (shown as Anonymous) on Microsoft Q&A

Troubleshooting answer for a Windows Sandbox that will not enable or start. It checks that virtualization shows Enabled in Task Manager, restarts Container Manager Services and the Hyper-V related services, and as a last resort reinstalls the feature after clearing the stale Sandboxes and Zygotes folders. The reinstall workaround involves temporarily turning off Defender protections, so re-enable them afterwards.

Quick steps

Task Manager, Performance: confirm Virtualization is Enabled
Restart Container Manager Services (then the other Hyper-V services if needed)
Last resort: uninstall the feature, delete the stale Sandboxes/Zygotes folders, reinstall
