>> create window alias

In a Powershell window with admin rights, execute:

`$ notepad $profile.AllUsersAllHosts`

In the profile.ps1 file that opens, put:

`$ set-alias -name pn -value pnpm`

Save the file and close the window. You may need to close any open Powershell window in order for the alias to take effect.
