You should save your alias in your profile (like in .bashrc in Linux). Hava a look to About_profile to choose your one.

$Profile var gives you the path to your profile file.

It exists 4 different profil files given by :

$profile.AllUsersAllHosts
C:\Windows\System32\WindowsPowerShell\v1.0\profile.ps1
$profile.AllUsersCurrentHost
C:\Windows\System32\WindowsPowerShell\v1.0\Microsoft.PowerShellISE_profile.ps1
$profile.CurrentUserAllHosts
C:\Users\JPB\Documents\WindowsPowerShell\profile.ps1
$profile.CurrentUserCurrentHost
C:\Users\JPB\Documents\WindowsPowerShell\Microsoft.PowerShellISE_profile.ps1
