此软和ccleaner一样为系统得力助手，本人用了很久了，so特此推荐。吼吼。

这个软件{zd0}的功能是带有Smart Defrag磁盘整理工具，比Perfect Disk5.0、Vopt、UltraDefrag、O&O Defrag Professional、Diskeeper强得多，什么优化功能本人觉得比什么“超级兔子”、“优化大师”好用多了，目前市场上{zyx}和最快的碎片整理软件，牛！(这两个软件也有他们的优势，不能全面否定）

Advanced System Care V3.XX虽然也还是区分free和pro(收费)，但是免费版并没有多大的功能限制。但本人呢还是喜欢pro，专业嘛，嘿嘿。现在此软本身是不区分的，也就是说你下载free版和pro版是一样的，关键是一个序列号的问题

首先下载此软，后面的下载地址为free版。

安装完成后打开，在左下角有个升级按钮，点击后输入注册码，断网xx就成pro了 蛮爽。

给几个注册码吧，注意：注册时需断网。
