在体验PowerShell 7并配置profile文件后发现，不同于PowerShell 5.1，使用ScreenFetch命令会报错：

所以我们想要为PowerShell和PowerShell Core设置不同的profile配置文件路径，方法如下：
将C:\Users\<username>\Documents\PowerShell中的Microsoft.PowerShell_profile.ps1复制到C:\WINDOWS\System32\WindowsPowerShell\v1.0中，则现在：
C:\WINDOWS\System32\WindowsPowerShell\v1.0\Microsoft.PowerShell_profile.ps1是PowerShell 5.1的配置文件；
C:\Users\<username>\Documents\PowerShell\Microsoft.PowerShell_profile.ps1是PowerShell 7的配置文件。
注意，如果你之前的配置文件名称是profile.ps1，则你需要将其文件名更改为Microsoft.PowerShell_profile.ps1。
这种方法有一个bug，如果你在前者的profile文件中加入ScreenFetch而后者不加入，尽管PowerShell 7不再执行ScreenFetch命令，但是PowerShell 5.1会将ScreenFetch执行两遍，我们只好将前者的profile文件中的ScreenFetch命令也删去，则PowerShell 5.1只执行一次ScreenFetch。
另外，更改PowerShell的profile文件的路径可使用命令
$profile = "NewLocation\profile.ps1"
