如果启用了Windows Update,请从.NET检查

using System.Diagnostics;

public static bool IsWindowsUpdateEnabled()
{
    var processStartInfo = new ProcessStartInfo("powershell.exe", "Get-ItemProperty -Path 'HKLM:\\SOFTWARE\\Policies\\Microsoft\\Windows\\WindowsUpdate\\AU' -Name 'NoAutoUpdate' | Select-Object -ExpandProperty 'NoAutoUpdate'")
    {
        RedirectStandardOutput = true,
        UseShellExecute = false,
        CreateNoWindow = true
    };

    using (var process = Process.Start(processStartInfo))
    {
        process.WaitForExit();
        var output = process.StandardOutput.ReadToEnd();
        return output.Trim() == "0";
    }
}

using System.Diagnostics;

public static void EnableWindowsUpdate()
{
    var processStartInfo = new ProcessStartInfo("powershell.exe", "Set-ItemProperty -Path 'HKLM:\\SOFTWARE\\Policies\\Microsoft\\Windows\\WindowsUpdate\\AU' -Name 'NoAutoUpdate' -Value 0")
    {
        RedirectStandardOutput = true,
        UseShellExecute = false,
        CreateNoWindow = true
    };

    using (var process = Process.Start(processStartInfo))
    {
        process.WaitForExit();
    }
}
