Answer 1

The variable is read only by default, but can be removed with the -Force switch to Remove-Variable. To make your change persistent across sessions, you can make a profile file which is much like a .bashrc (For bash on Linux) except for Powershell.

In your Documents directory (normally C:\Users\YOUR_USERNAME_HERE\documents) for your user account, create a WindowsPowerShell folder (named exactly like that) if one does not already exist. Inside the folder, create a text file called profile.ps1 (ensure it's not profile.ps1.txt).

Inside the file, place anything you want executed when you open Powershell.

example:

Write-Host "Hi John, welcome back!"
Remove-Variable -Force HOME
Set-Variable HOME "C:\Users\khornsby"

result:

You can use help about_profiles to see more details about this. Do not forget to sign your script.
