ToggleMOUSE 4.4.6 (5千字)
http://www.toggle.com这是个很好的鼠标增强工具。它可以输入注册码，不过这里我们不是从输入注册码
时开始跟踪，而是跟踪它启动时的判断过程，从而找到注册码。
用RegMon看一下，发现它启动的时候要读如下几个键：
HKEY_CURRENT_USER\Software\ToggleSoftware\ToggleMOUSE\Registration\Name
HKEY_CURRENT_USER\Software\ToggleSoftware\ToggleMOUSE\Registration\Company
HKEY_CURRENT_USER\Software\ToggleSoftware\ToggleMOUSE\Registration\RegNumber
反汇编其主程序，找到如下的代码片段：

根据以上代码可知校验和等于注册码和常数0x53213321异或，校验和放在这里：
HKEY_CURRENT_USER\Software\ToggleSoftware\ToggleMOUSE\Settings\LastPageIndex
注册机也很好写，因其计算过程很简单。
