1️⃣ 一键设置：IPv4 优先，IPv6 备用（推荐）PowerShell 窗口里运行就行
# 以管理员身份运行，设置 IPv4 优先
Set-ItemProperty -Path 'HKLM:SYSTEMCurrentControlSetServicesTcpip6Parameters' -Name 'DisabledComponents' -Value 32 -Type DWord
Write-Host "✅ 已设置系统优先使用 IPv4，IPv6 作为备用" -ForegroundColor Green
Write-Host "ℹ️ 需要重启电脑才能完全生效" -ForegroundColor Yellow2️⃣ 补充：恢复默认（如果以后想改回来）
# 恢复系统默认的协议优先级
Set-ItemProperty -Path 'HKLM:SYSTEMCurrentControlSetServicesTcpip6Parameters' -Name 'DisabledComponents' -Value 0 -Type DWord
Write-Host "✅ 已恢复系统默认设置" -ForegroundColor Green
Write-Host "ℹ️ 需要重启电脑才能完全生效" -ForegroundColor Yellow
验证是否生效
