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
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！

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！)

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

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。

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！
