之前一個朋友拿著一台 Lenovo 筆電跟我說,他設定了 Win7 的密碼,但是怎麼輸入都是錯的!原本想叫他重灌就好,可是裡面有重要資料,而且他的硬碟是有鎖的,就是拔出來也不見得能夠複製。更慘的是,他把 ThinkVantage 的 Partition 也破壞了。所以只好死馬當活馬醫了。
網路上查了很久,也試了幾個方法,最後總算找到一個好方法了!就是用以下的工具,做成 USB 開機,直接把密碼改掉!
在這邊可以下載
 
 
下載回來後,可以照以下步驟:
 
如果無法正常開機,可以參考這篇:忘記 Windows 的密碼
步驟
1.
製作 USB Boot disk
先將 zip 檔解開,並且複製到你的 USB 隨身碟中。
然後進入 DOS 模式 (最好是系統管理者權限)
切換到 USB 那槽 (ex: X: ),然後輸入
X:syslinux.exe -ma X:
如果沒有錯誤訊息,那就是成功了!
2.
用 USB 開機
接下來的部分比較複雜,如果開機成功,則會看到以下訊息 (若不成功可能需要檢查 BIOS 設定,或是你的機器根本不支援 USB 開機,那就要用光碟來開機了!)

  Press enter to boot, or give linux kernel boot options first if needed.
  Some that I have to use once in a while:
  boot nousb          - to turn off USB if not used and it causes problems
  boot irqpoll        - if some drivers hang with irq problem messages
  boot nodrivers      - skip automatic disk driver loading
 
  boot:
直接按 <Enter> 即可。然後是一串開機訊息,可以不必太認真看。(以下訊息是抓他網站上的,因為修復時沒有抓畫面,所以直接用網站的說明!)

  =========================================================
  There are several steps to go through:
  - Disk select with optional loading of disk drivers
  - PATH select, where are the Windows systems files stored
  - File-select, what parts of registry we need
  - Then finally the password change or registry edit itself
  - If changes were made, write them back to disk
 
  DON'T PANIC! Usually the defaults are OK, just press enter
               all the way through the questions
3.
選擇正確的 Partition 然後重設密碼
接下來,如果看到這個訊息,就表示抓到你的硬碟了。
=========================================================
 ¤ Step ONE: Select disk where the Windows installation is
 =========================================================
 
 Disks:
 Disk /dev/sda: 42.9 GB, 42949672960 bytes
 
 Candidate Windows partitions found:
  1 :        /dev/sda1   40958MB BOOT
 
Please select partition by number or
  q = quit
  d = automatically start disk drivers
  m = manually select disk drivers to load
  f = fetch additional drivers from floppy / usb
  a = show all partitions found
  l = show propbable Windows (NTFS) partitions only
 Select: [1]
這時需要選擇 Partition ,因為只有一個,所以輸入 1 (我修復的那台機器有三個 Partitions,一開始我是選錯的,就會發生找不到 windows 的狀態,然後重選,所以除非你電腦上有裝多套 Windows ,否則選錯是不會怎麼樣的。
輸入 1 後:
Selected 1
 
 Mounting from /dev/sda1, with filesystem type NTFS
 
 NTFS volume version 3.1.
 
4.
設定 Windows 路徑
=========================================================
 ¤ Step TWO: Select PATH and registry files
 =========================================================
 What is the path to the registry directory? (relative to windows disk)
 [WINDOWS/system32/config] :
一般來說,除非你改目錄,否則都應該是這個目錄。
接下來會出現:
-rw-------    2 0        0          262144 Feb 28  2007 BCD-Template
 -rw-------    2 0        0         6815744 Sep 23 12:33 COMPONENTS

 -rw-------    1 0        0        15728640 Sep 23 12:33 SOFTWARE
 -rw-------    1 0        0         9175040 Sep 23 12:33 SYSTEM
 drwx------    1 0        0            4096 Nov  2  2006 TxR
 drwx------    1 0        0            4096 Feb 27  2007 systemprofile
 
 Select which part of registry to load, use predefined choices
 or list the files with space as delimiter
 1 - Password reset [sam system security]
 2 - RecoveryConsole parameters [software]
 q - quit - return to previous
 [1] :
選擇 1 就可以重設密碼了。
5.
重設密碼
Selected files: sam system security
 Copying sam system security to /tmp
 
 =========================================================
 ¤ Step THREE: Password or registry edit

後記
現在流行雲端,其實自動備份的軟體,像是 drop box,或是 Windows Mesh 都是不錯的選擇,多多備份比較安全囉。希望大家都用不到這個工具!
