powershell - Remove all variables

Question

I want to remove all user-created variables at the start of a script.

Currently I am doing Remove-Variable -Name * but it tries to dele

Answer 1

I suppose you could make a list of all the variables you don't want to delete.

$DontDelete = '$','?','^','args',...,'WhatIfPreference'

Then delete the variables that are not on the Don't Delete list.
