Shadow Defender (影子卫士) 是一款体积小巧却功能强大的系统还原、保护程序，支持多分区，支持转储，支持排除，工作原理类似于沙盘软件的轻量级系统保护工具，其中文名为影子卫士，喜欢影子系统的朋友可以尝试下。你可以设置一个分区为影子模式，可以是系统分区和其它分区，进入此模式后，你对此分区上所做的任何改动都会在重启后失效，即使你在测试一个病毒。Shadow Defender 的不同之处在于支持排除与转储功能。你可以把处于影子模式中的文件或文件夹置入排除列表，那么你的所有更改将被保存到原始分区。能防机器狗和PassDiskProtect_C.exe。占用系统资源极低。关闭“DefenderDaemon.exe”进程后保护依然有效。软件有着漂亮的界面和直观的设置选项，特别是在转储和排除方面胜人一筹。

软件有着漂亮的界面和直观的设置选项，桌面上的提示标签很漂亮，还可以随时移动并且可以此唤出主界面，给人感觉超棒。特别是在转储和排除方面胜人一筹。

Shadow Defender与Powershadow(影子系统)相比优势：

1：程序核心更为先进，程序体积虽然只有Powershadow(影子系统)的1/83，但是绝不逊色。

2：从我个人研究的角度来说Shadow Defender更为安全，保护能力更强大，占用系统内存更小。
