今天遇到一件囧事，长时间不进Windows环境结果把自己设置的密码给忘记了，于是便发了一条微博。热心朋友一大堆，给我推荐各种各样的方法，自己也到网上搜了一搜，原来在Linux下去除Windows的密码是那么简单。方法步骤如下：
一、安装工具chntpw
这个工具应该在各大发行版的官源里都存在（Linux对Windows的安全环境考虑真是没得说。==！）。直接用你的发行版里最常用的安装方式安装即可。
比如Archlinux– sudo pacman -S chntpw
二、使用工具
挂载windows系统分区盘，进入到 windows/system32/config中，就地打开终端，运行如下命令：
sudo chntpw SAM
会得到如下提示：
chntpw version 0.99.6 110511 , (c) Petter N Hagen Hive name (from header): ROOT KEY at offset: 0×001020 * Subkey indexing type is: 666c File size 262144 [40000] bytes, containing 5 pages (+ 1 headerpage) Used for data: 233/17736 blocks/bytes, unused: 16/2584 blocks/bytes. * SAM policy limits: Failed logins before lockout is: 0 Minimum password length : 0 Password history count : 0 | RID -|———- Username ————| Admin? |- Lock? –| | 01f4 | Administrator | ADMIN | *BLANK* | | 01f5 | Guest | | dis/lock |

RID : 0500 [01f4] Username: Administrator fullname: comment : ���:(�)��n7 homedir :
User is member of 1 groups: 00000220 = Administrators (which has 1 members)
Account bits: 0×0210 = [ ] Disabled | [ ] Homedir req. | [ ] Passwd not req. | [ ] Temp. duplicate | [X] Normal account | [ ] NMS account | [ ] Domain trust ac | [ ] Wks trust act. | [ ] Srv trust act | [X] Pwd don’t expir | [ ] Auto lockout | [ ] (unknown 0×08) | [ ] (unknown 0×10) | [ ] (unknown 0×20) | [ ] (unknown 0×40) |
Failed login count: 0, while max tries is: 0 Total login count: 81 ** No NT MD4 hash found. This user probably has a BLANK password! ** No LANMAN hash found either. Sorry, cannot change. Try login with no password!
- – - – User Edit Menu: 1 – Clear (blank) user password 2 – Edit (set new) user password (careful with this on XP or Vista) 3 – Promote user (make user an administrator) (4 – Unlock and enable user account) [seems unlocked already] q – Quit editing user, back to user select Select: [q] >
很显然，选1清除密码;选2重设密码;选3不知不觉提升用户权限，哈哈;选4启用或者关闭某个用户。我果然选1，重启进入Windows一路无阻！
