OpenClaw 作为 Windows 平台的自动化框架，其 Skill 插件机制广泛应用于办公自动化、IT 运维等领域。在 Windows 环境下开发自定义 Skill 需要考虑以下特性：

COM 组件交互需求：需显式声明 CoInitializeSecurity 设置
UAC 权限边界：管理员权限与非特权运行模式的切换
CRT 依赖版本：推荐使用静态链接规避运行时冲突

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\OpenClaw\JobObject]
"MaxWorkingSetSize"=dword:02000000
"AffinityMask"=dword:000000FF

运行时冲突 ：使用 DLL 隔离

<!-- application.manifest -->
<dependency>
  <assemblies>
    <assemblyIdentity type="win32" 
      name="Microsoft.VC90.CRT" version="9.0.xxxxx" 
      processorArch="x86"/>
  </assemblies>
</dependency>

权限审计 ：使用 SID 分析

Get-Process -Name OpenClawHost | Select-Object @{Name='SDDL';Expression={($_.Handle).ToString()}} | Format-List

CPU 节流 ：注册表策略

[HKEY_LOCAL_MACHINE\SOFTWARE\OpenClaw\QualityOfService]
"MaxCPUUsage"=dword:00000050
