关掉机房助手 + 恢复被改的功能 —— 单文件版

一个文件装下全部内容：6 段代码 + 操作步骤 + 排错表。 这台机器 Win+R（运行）已被禁用，所以全程只有双击和右键，不用敲任何命令。

耗时：约 3 分钟。需要：管理员账户。

第 0 步：把 6 段代码存成 6 个文件

双击桌面「计算机」→ 地址栏输入 C:\Users\Public → 回车；
里面没有 tool 文件夹就新建一个，命名为 tool；
打开「记事本」，把下面每一段代码整段粘进去，「文件 → 另存为」→ 保存类型选「所有文件」→ 编码选 ANSI → 文件名一栏连双引号一起照抄本文给出的那一行。

6 个文件名与完整路径（一字不差地抄进「文件名」框）：

"C:\Users\Public\tool\01-recon.vbs"
"C:\Users\Public\tool\02-kill.vbs"
"C:\Users\Public\tool\03-restore.vbs"
"C:\Users\Public\tool\04-restore-hosts.bat"
"C:\Users\Public\tool\05-verify.vbs"
"C:\Users\Public\tool\06-dump-password.vbs"

文件名全用英文小写 + 连字符，不用中文、不用空格，避免编码和路径上的特殊情况。 双引号必须有：不加引号，记事本会给你存成 01-recon.vbs.txt，双击就不执行了。 编码必须是 ANSI：存成 UTF-8 脚本会报「语法错误」。 文件名一个字都不能改：序号、连字符、扩展名都要原样（02-kill.vbs 不是 02_kill.vbs）。

为什么不能放桌面或 C:\Users\Public 根下：助手会监视那些位置并删掉 .bat/.vbs， C:\Users\Public\tool 这个子目录它不监视。

第 1 步：侦察（只读，不用管理员）

运行顺序（必须按这个顺序）

顺序	文件（完整路径）	怎么运行	预期结果
1	`C:\Users\Public\tool\01-recon.vbs`	双击	弹记事本，`total = 2` 或 `3`
2	`C:\Users\Public\tool\02-kill.vbs`	双击 → UAC 点是	弹 `2-kill OK`，`remain = 0`
3	`C:\Users\Public\tool\03-restore.vbs`	双击 → UAC 点是	弹 `3-restore OK`
4	`C:\Users\Public\tool\04-restore-hosts.bat`	右键 → 以管理员身份运行	末行 `hosts = 824 bytes`
5	`C:\Users\Public\tool\05-verify.vbs`	双击	弹 `ALL PASS (5 checks)`
6	`C:\Users\Public\tool\06-dump-password.vbs`	双击	弹记事本，`pass.txt` 里有 `n = ...`

只有 .bat 的右键菜单里有「以管理员身份运行」，.vbs 没有 —— 所以第 4 步右键，其余双击。 .vbs 会自己弹 UAC 再以管理员身份重跑一遍，看到 UAC 一定点「是」（默认是「否」，按回车等于取消）。第 6 步是只读的，任何时候都能跑，不改变任何东西；它只把注册表里的值抄到 pass.txt。

`02-kill.vbs` 的输出怎么读

结果存在 C:\Users\Public\tool\kill.txt，关键几行：

行	含义
`StopService rc=0`	服务已停（`rc=1060` 也表示服务本来就不存在，可以继续）
`gone after check N`	服务进程真的退出了，可以杀进程
`judge = xxx.exe`	识别到的裁判（5 个字母的那个）
`kill ... rc=0`	该进程已被结束
`killed = 2` / `3`	结束的总数
`remain = 0`	5 秒后没有残留，成功

若出现 zmserv.exe still alive after 10 s -- ABORT： 这是脚本主动放弃，因为服务没停就杀进程会让机器约 80 秒后直接断电。重启一次再重试。

`06-dump-password.vbs` 抓到了什么

输出 C:\Users\Public\tool\pass.txt，分三段：

段	内容
A	三个已知名字 `n` / `dtmm` / `czmm` 的值（没有就写 `<not present>`）
B	`HKCU\Software` 下全部值（名称、类型、内容）
C	`HKCU\Software\jfglzs` 下全部值（有的话）

n 是助手设置的退出密码，但存的不是明文，而是一串 64 位十六进制。把 pass.txt 交给我，我来分析每个值分别是什么、以及能不能还原。

出事了怎么办

现象	原因	处理
双击后没反应	UAC 没点「是」	重新双击，点「是」（别按回车）
文件变成 `xxx.vbs.txt`	另存为时文件名没加双引号	删掉重存，文件名连同引号一起抄
提示「找不到文件 wscript」	文件关联被改	右键 `.vbs` → 打开方式 → `C:\Windows\System32\wscript.exe`
屏幕被蓝底红字锁住	裁判发现文件被杀	`Ctrl+Alt+Del` → 启动任务管理器 → 结束那个 5 字母进程
鼠标点哪都没反应	鼠标被限制在左上 500×100	只用键盘：`Ctrl+Alt+Del` → 任务管理器
机器突然断电	服务先死、进程后死，80 秒倒计时走完	重启后重来，严格按 1→2→3→4→5
`remain` 不是 0	裁判被重新拉起	再双击一次 `02-kill.vbs`
脚本报「语法错误」	保存成了 UTF-8	重新另存为，编码选 ANSI

这套脚本不做什么

不删安装目录（C:\f40967408）、不删 C:\windows\jf、不删服务。这些属于「彻底清除」，不可逆，而且本套的目标只是「停掉 + 恢复可用」。
重启后助手会自己回来（服务是自启动、无 Run 键拉起），这是可预期的，等于留了退路。

关于提示文字是英文

VBScript 按系统 ANSI 读文件，脚本里写中文在不同编码下会变乱码甚至报错。所以脚本内部的提示统一用英文；文件名同样统一用英文小写，避免零宽字符、全角符号、编码这类问题。

关掉机房助手 + 恢复被改的功能 —— 单文件版

第 0 步：把 6 段代码存成 6 个文件

第 1 步：侦察（只读，不用管理员）

第 2 步：停止监控（要管理员）

第 3 步：恢复设置（要管理员）

第 4 步：还原 hosts（要管理员）

第 5 步：验证（只读，不用管理员）

第 6 步：抓注册表里存的密码（只读，不用管理员，随时可做）
