一、首先自然是先清理一下我们的开机启动项了，随便找一个地方，然后新建一个文本文档，把以下的代码复制进去，然后后缀名由.txt改成.bat,接下来我们只要双击它就能自动清理开机启动项了。

二、还有的就是清理一下常见病毒、插件和恶意代码了，步骤和上边一样， 随便找一个地方，然后新建一个文本文档，把以下的代码复制进去，然后后缀名由.txt改成.bat,接下来我们只要双击它就能自动清理常见病毒、插件和恶意代码，清理完会自动关闭哦。

三、最后一个就是在Windows在安装和使用过程中都会产生相当多的垃圾文件，包括临时文件(如：*.tmp、*._mp)日志文件(*.log)、临时帮助文件(*.gid)、磁盘检查文件(*.chk)、临时备份文件(如：*.old、*.bak)以及其他临时文件。特别是如果一段时间不清理IE的临时文件夹“Temporary Internet Files”，其中的缓存文件有时会占用上百MB的磁盘空间。这些LJ文件不仅仅浪费了宝贵的磁盘空间，严重时还会使系统运行慢如蜗牛。这点相信你肯定忍受不了吧!所以应及时清理系统的LJ文件的淤塞，保持系统的“苗条”身材，轻松流畅上网!朋友来吧，现在就让我们一起来快速清除系统垃圾吧!!步骤同上，双击就能清理垃圾啦。
