あるときから以下のエラーが出るようになる。これまではエラーなしでVMは起動できていたのだけどなんでだろ？Windows Updateの影響？

There was an error while executing `VBoxManage`, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below. Command: ["startvm", "30913ae9-a20f-411a-b220-011855a967d1", "--type", "headless"] Stderr: VBoxManage.exe: error: Raw-mode is unavailable courtesy of Hyper-V. (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT) VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole
ネットで対処法を調べると、Hyper-Vを明示的に無効化すれば解決するらしい。
以下の手順でHyper-Vを無効化する。
1. OptionalFeatures.exeを実行してHyper-Vをアンチェックする。
2. 管理者権限でコマンドプロンプトを開いて以下を実行する。
> bcdedit /set hypervisorlaunchtype off
