Learn about Windows PowerShell
Summary: Here is the answer to the final question in Mini-Scripting Games 2014.
You created a constant variable in your Windows PowerShell console. Now, when you attempt to delete the variable, you get an error message. How can you remove a constant variable?
A constant variable is created by using the New-Variable cmdlet, for example:
New-Variable c "c" -Option Constant
After a variable is created as a constant, it cannot be removed until the console (or ISE) is closed and reopened.
