解决方法：管理员身份打开PowerShell执行以下命令

该命令CMD无效，无Powershell的机器可以手动到注册表添加相关项

New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults\AllowDefaultCredentials -Name Hyper-V -PropertyType String -Value "Microsoft Virtual Console Service/*" -Force
New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults\AllowDefaultCredentialsDomain -Name Hyper-V -PropertyType String -Value "Microsoft Virtual Console Service/*" -Force
