_build/watch_stability.py 连续打公网统计可用率(验证隧道加固效果)
_build/desktop_state.py 列出当前可见窗口 + 输入桌面名
(排查"桌面消失/一片蓝"这类问题用)
这两个是查 2.1.1 / 2.1.2 那两个问题时写的,以后还会用到。
顺便记一笔当时的排查结论(2026-10-08):
用户报"桌面消失、一片蓝、有个蓝色窗口",查下来:
* 输入桌面是 Default(正常),explorer 在跑
* 那 9 个"全屏窗口"全是 Windows 自己的 UWP 组件
(开始菜单 / 搜索 / 锁屏 / 输入法),程序枚举时会误报全屏
* 真正开着的是「设置」App 和任务管理器
* 自启项里没有 ykxmz,也没有残留的隐藏桌面或测试进程
* 18:42:41 有一次**非正常关机**(Kernel-Power 41 / EventLog 6008),
19:58 重启。没有任何蓝屏或硬件错误记录 ——
最符合"掉电或硬挂",不是软件崩溃。

r'''看当前桌面/窗口的真实状态 —— 诊断"桌面消失、一片蓝"。
|
|
|
|
用户报:"我现在桌面消失了,电脑一片蓝,然后还有个蓝色的窗口"。
|
|
|
|
已知:
|
|
18:42:41 机器异常关机(Kernel-Power 41 / EventLog 6008,无蓝屏记录)
|
|
19:58:23 重新启动
|
|
20:01:37 explorer 起来
|
|
自启项里没有 ykxmz,当前也没有 ykxmz 在跑
|
|
|
|
要查的是:现在屏幕上到底有什么、是不是有全屏窗口盖住了桌面。
