关于系统密码破解的问题

关于系统密码破解的问题 小技巧 阅读41 评论0 随着电脑在各行业普及，人们对电脑的应用也越来越多，同时人们对自己的信息安全也越来越关注，各种加密算法不断出现，公司里的员工纷纷都将自己的文件、电脑加了把锁，可是，很多人在给自己的电脑加锁之后却丢了钥匙---密码。再你丢了相关密码之后怎么办,不要急，让我 慢慢给你讲相关的开锁。 一、忘记开机密码 开机密码是指你在打开电脑开机自检后就跳出的密码。这时你只有输入正确的密码后操作系统才启动。这种密码出现时，你就想进入电脑的BIOS设置都不行，所以安全性相对要好(建议笔记本电脑不要设置此类密码。因为一旦忘记密码，然后又丢了相应的解密盘的话，你可就要去 笔记本产商维修店去烧钱了)。 解决方法:打开机箱，把主板上的CMOS锂电池取出来，过一会儿(5 -10分钟)，再放进去,密码自动消失。 原理:因为开机密码是通进BIOS设置的，它会保存在主板上CMOS中，这种存储器在长时间掉电后内容会消失，所以密码也随之消失。 (a) construct safe volunteers is a global task.

It is the significant move that strengthen the comprehensive management of social management, to maintain the stability of the overall situation of social order, is to do a good job of prevention and treatment work under the new situation, constructing the harmonious relationship between the police and the people of a strong starting point, with the central, the provincial, city and county on strengthening and innovating social management, do a good job work of the masses of the major decision is consistent with the spirit.

TFS的话有些启动盘不能操作文件，因为这个操作要更改或删除文件。 若是FAT的话用一般的Windows98启动盘就可以启动电脑，而NTF S则要其它工具，比如说NTFSDOS这个小软件，它可以通过制作两 张Floppy启动盘后来操作NTFS文件格式下的文件。用启动盘启动电 脑(现在是在dos状态下)，进入系统所在的分区(如:C盘)将c:\ windows\system32\config\sam文件改名或删除则在下次登录密码 为空就可以登录。 原理:因为c:\windows\system32\config\sam这个文件在操作系统 中相当于一个数据库文件用于保存当前系统用户的密码，当删除或更改 此文件之后，系统就认为没有密码，下次启动时就会自去产生一个SA M文件。 五、忘记Windows XP登录密码 解决方法一、用net 命令(假设忘记密码的用户名为LUOYONG) 我们知道在Windows XP中提供了“net user”命令，该命令可以添 加、修改用户账户信息，其语法格式为: net user [UserName [Password | *] [options]] [/domain] net user [UserName {Password | *} /add [options] [/domain] net user [UserName [/delete] [/domain]] (a) construct safe volunteers is a global task.

(II) volunteers in peace building is the concrete embodiment of the basic principles of public security work.
