破解心得之Windows優化大師篇
軟體名稱：Windows優化大師
版本：4.20
作者：時空幻影
時間：2001年11月25日
使用工具：TRW2000 V1.22已註冊版、CASPR（脫殼工具）、PW32DSM白金版漢化版
先用CASPR脫掉WINDOWS優化大師.EXE和OCTODLL.DLL的殼，然後進入TRW2000，再進入Windows優化大師，點選“軟體註冊”，
然後在註冊者姓名欄中填入自己的名字，按Enter鍵，點選“取消”，就會看見註冊申請碼，在註冊認證碼的兩個欄中分別隨便填入一
個長度為8的十進位制數。按CTRL+N啟用TRW2000後，設“萬能斷點”BPX HMEMCPY，回車，然後按F5回到WINDOWS下，點選“註冊認證”
會被攔下，輸入指令BD *、PMODULE，回車，然後按F10過了幾個RET後會來到如下所指的地方：

至此我們已經對《WINDOWS優化大師》的註冊碼機制進行了比較完全的分析，所以我相信大家對其寫序號產生器沒有太大的困難了。
希望大家沒事的時候寫一寫序號產生器，以提高自己的程式設計水平！！！
後記：今天終於買到了看雪兄的書了（嗚~~~~~~~~~~~~~），真是等你等到我心痛啊！！！

破解心得之Windows優化大師篇（補充）
軟體名稱：Windows優化大師
版本：4.20
作者：時空幻影
時間：2001年11月25日
使用工具：TRW2000 V1.22已註冊版、CASPR（脫殼工具）、PW32DSM白金版漢化版
在我破解的過程中，我發現在輸入註冊碼後軟體可以變成已註冊的，也能進行自動優化，但當退出後再重新執行又變成未註冊的了。
經過跟蹤除錯分析後，我發現原來是由於我為了能夠反編譯OCTODLL.DLL，對該檔案進行了脫殼，並把脫殼後的檔案拷貝到軟體目錄下覆蓋
了原來的未脫殼的檔案而導致了軟體變成了未註冊的。
現在讓我們來看一看有哪些因素會導致軟體變成了未註冊的：

另外值得注意的是在寫序號產生器的時候，當求Code2是不要直接使用0x14，因為算出來的註冊碼與作者不符。其實Code2並不唯一，
除了最高2位和低16位不能動，剩餘的14位可以為任意數。經過我的分析，使用0x93E0014算出來的註冊碼才與作者相符。
