前言
现在程序处理使用Linux下软件的机会越来越多，但是也离不开QQ，office这些win下面的软件。win10现在可以启用Ubuntu子系统后大大提高了生产力，之前用过Virtual Box的虚拟机后期扩容是个很大的麻烦。现在子系统完全使用桥接网络，可以在/mnt/下面访问win下面文件，除了速度慢点，其他都很好用，本文纯粹记录本次子系统的使用。
系统安装
系统安装很简单，直接打开开发者模式之后启用适用于windows的linux的子系统之后重启电脑进入win的应用商店搜索Ubuntu安装即可。
系统优化
系统的软件源因为国内不可控原因造成连接速度很慢或者无法连接的现象，切换软件源势在必行。我直接添加了阿里云、科大和清华的源。之前有人只添加过一个，但我发现会有packages不全的问题，我索性全部添加进去了，软件也全部能检索到。
使用该命令修改
sudo vim /etc/apt/sources.list
输入insert进入修改模式。之后把之前的deb全部注释掉后把以下内容加入即可。
#阿里云

之后使用命令进行更新软件
sudo apt-get update
sudo apt-get upgrade
期间需要输入yes N次
系统美化
cmd自带的界面太丑，我用的Cmder代替原来的界面，感觉还不错。之前用的ConEmu会有复制代码前几个字符会被覆盖的问题，这个Cmder目前完美。由于我们装的Ubuntu就是bash，所以不需要安装Full版本的Cmder，直接用mini就好了，这个是portable版本，也就是绿色软件，下载后解压到一个文件夹下就可以用，打开之后进行如下设置可以进入Ubuntu。
打开cmder直接进入的是cmd，我们可以在设置中更改它的startup方式，选择command line ，填入bash -cur_console:p。
主题在Features-Colors中可以设置，透明度在Transparency中设置
之后重启就可以进入Ubuntu子系统了。
