skype的用户名无法更改，用户名不是昵称，一旦注册就无法更改，但可以重新注册一个。
下面介绍创建新用户名的方法，具体步骤如下：
1、首先我们进入引擎搜索， 搜索【skype】，搜索后一定要认准skype官网进入官方页面。

2、然后我们在skype官方页面上选择【下载】，如下图红色箭头所指位置。

3、根据所使用的设备情况选择不同类型，我们在这里选择【电脑】为例。然后根据我们的电脑系统类型下载合适的版本，windows8.1和mac有专用版本，win7及以下系统下载选择绿色通道下载。注意选择的版本一定要和电脑系统相匹配。

4、当我们将skype安装包下载后，找到下载位置并找到安装包，双击图标后进入安装界面。

5、安装开启之前注意设置安装语言和安装位置更改，这一点尤为重要。点击【浏览】即可重新设置安装位置，如下图红色箭头所指。

6、然后按界面提示点击继续即可，到这个页面时注意根据自己的需要进行选择是否安装skype页面拨号。如果不需要的话可以选择不安装，如下图红色箭头所指的位置。
