🚀 本版本新增特性 (New Persistent Features)

在保留原版极其出色的 COM 劫持代理去水印机制的基础上，针对现代 Windows 系统（Windows 11 26H2/24H2/23H2、Windows 10）进行了防更新还原持久化升级： Based on the excellent original COM hijacking DLL proxy mechanism, this version introduces a persistence upgrade against Windows Updates for modern Windows systems (Windows 11 26H2/24H2/23H2, Windows 10):

1. 一键一劳永逸（Click Once, Set and Forget）：
   • 提供了编译完成的无缝单文件独立主程序 uwd_persistent_installer.exe。
   • 只需运行并点击一次 Install，安装完成后即可直接关闭并删除软件本身，无需常驻或保留安装包。
   • Provides a fully compiled standalone installer uwd_persistent_installer.exe.
   • Simply run it and click Install once. After installation, you can safely close and delete the software itself. It does not need to run in the background.
2. 自动防 Edge / Windows Update 还原守护 (UWD_PersistenceGuard)：
   • 解决了 Edge 浏览器更新或 Windows 累积更新静默将注册表项 HKCR\CLSID\{ab0b37ec-56f6-4a0e-a8fd-7a8bf7c2da96}\InProcServer32 改回默认 explorerframe.dll 导致水印复发的问题。
   • 自动向系统注册轻量巡检任务，检测到更新还原后自动静默修复，0 RAM 内存常驻，0% CPU 开销。
   • Solves the issue where Edge browser updates or Windows Cumulative Updates silently reset the registry key HKCR\CLSID\{ab0b37ec-56f6-4a0e-a8fd-7a8bf7c2da96}\InProcServer32 back to explorerframe.dll, causing the watermark to reappear.
   • Automatically registers a lightweight scheduled task that silently detects and repairs the registry key if it is reverted, with 0 RAM footprint and 0% CPU overhead.

🔬 工作原理 (How it works)

• 去水印逻辑 (Watermark Removal Logic)：通过 COM 劫持与 DLL 代理技术（painter_x64.dll），拦截 Explorer 绘制桌面水印文本的过程。(Intercepts the Explorer's rendering of desktop watermark text via COM Hijacking and DLL proxying with painter_x64.dll.)
• 持久化防复发逻辑 (Persistence Logic)：利用 Windows 原生计划任务（UWD_PersistenceGuard），在开机/登录时静默校验注册表 CLSID 状态，确保在被 Edge/Windows Update 强行还原后能毫秒级自动修复。(Utilizes a native Windows Scheduled Task (UWD_PersistenceGuard) that silently verifies the registry CLSID status at boot/login, ensuring millisecond-level automatic repair if forcefully reverted by Edge or Windows Update.)
