单位一电脑登陆输入密码后注销，安全模式和最后一次正确配置都不能解决，其实登陆后注销的原因就2个，系统文件破坏被删除，注册被修改，而此中的系统文件主要为三个Explorer.exe %SystemRoot%\system32\logonui.exe C:\WINDOWS\system32\userinit.exe，而注册表的键值就如下所示
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"Shell"="Explorer.exe"
"Userinit"="C:\\WINDOWS\\system32\\userinit.exe,"
"UIHost"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,\

从安装光盘里面提取userinit.exe文件（在安装光盘i386目录下，文件名是USERINIT.EX_,
用expand命令即可把userinit.exe解压出来），然后放到%systemroot%\system32目录里面即可
注意:expand命令这样使用
expand 光盘盘符:\i386\USERINIT.EX_ 系统盘盘符:\Windows\system32
或者用深度的系统进入Win PE，然后再提取这几个系统文件到系统中，打开系统的注册表，修改即可
