1 你是说下载速度还是游戏速度？？
下载速度要是想一样快的话
在家里拉光纤 下载速度可以跟网吧一样快~
如果是游戏速度 我感觉网吧的游戏网速 还没我在家里玩的舒服
2 在家里的电脑上安装还原系统有点不太可能
直接在家安装影子系统 默认设置为 完全影子 模式
在该模式下 你在电脑上所有的操作在电脑重启之后就没有了
1。这是不太可能的。网吧都是光纤上网。快着呢……
2。网吧的都设置过的。要不然你下次整电脑的时候叫别人也帮你设置一份。
这个容易：只要你改造一台高速的策略路由器（如RouterOS,可用旧电脑改造，配置：845芯片组+赛扬2.4G+512兆内存+两张四口的百兆网卡足够，最好是有四个以上的可用PCI插槽，以备扩充），编辑好策略路由程序（此程序要求具备智能分包，多线路合并等功能）就行了，然后准备四条线路（两条铁通两兆，我这里的年费共是736元；一条网通两兆，我这里的年费是650元，一条电信两兆，我这里的年费是1076元。这样四条合并共八兆，也就2462元，折合每有也只205元。）相比之下，网吧进线一般是10兆光纤，且年费要10000元左右（我这里的行情），那要实惠的多，网速却比网吧要快得多（这是因为网吧托机多）。
至于你的第二个问题，就简单了，只要在你的电脑上装个影子系统，将你要下载的内容保存到影子系统保护的那个盘就行了，重启后，下载的内容在影子系统的保护下全部消失。
也许第一个问题对你来说比较不易解决，但可以叫人帮忙，第二个就容易多了，相信你自个都能解决。
= =网吧是光纤的81Mb饿。。。。速度当然快！ 家里的电脑，我们用的宽带，带宽通常在888Kb-8Mb之内， 网吧的当然不能和家里比！
可以释放20%
宽带速度
1、单击“开始－运行”，输入gpedit.msc回车后即可打开“组策略对象编辑器”。
2、展开“计算机配置－管理模板－网络－qos数据包计划程序”，双击右面设置栏中的“限制可保留带宽”，在打开的属性对话框中的“设置”选项卡中将“限制可保留带宽”设置为“已启用”，然后在下面展开的“带宽限制（％）”栏将带宽值“20”设置为“0”即可。
3、修改完之后，我们可以重新打开ie浏览器或者用bt或者迅雷下载文件，发现上网和下载的速度是不是明显提升了？
4、对win7，xp和vista均有效。
