Windhawk修改窗口关闭按钮颜色失败：多方案尝试无效求助

我尝试通过Windhawk（窗口模组分享平台）修改Windows 11窗口关闭按钮的悬停颜色，先后试过以下方案，但均完全无效：

• 修改DwmSetWindowAttribute以更改DWMWA_CAPTION_COLOR
• 挂钩DwmGetWindowAttribute而非DwmSetWindowAttribute
• 拦截WM_NCPAINT消息自定义绘制关闭按钮
• 使用窗口子类化创建子窗口的Overlay Button方案

以下是我尝试的Overlay Button方案代码：

# 自定义覆盖式关闭按钮模组
本模组添加一个可自定义悬停颜色的覆盖式关闭按钮，通过在原有关闭按钮上方创建一个小型子窗口实现。

## 特性
- 可自定义悬停颜色的关闭按钮
- 适用于Windows 11各类应用
- 保留原窗口功能
