PowerShell Setting up a folder to open in - powershell

Question

My teacher gave me this instruction : "To set-up the default folder for PowerShell to open in, right click the PowerShell icon in the tool tray and select Properties. In the Properties dialog box and in the Start in: text box enter the path to the new directory “C:\Users\Administrator\MyScripts”, then click OK."
However when I go into the properties tab I do not see what he is talking about :( .
This is what I see:
How do I I Do what he wants?

Answer 1

Your teacher is asking you to change the properties of the executable. You are currently looking at the PowerShell console properties.
As you can partially see mine is located:
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe

Answer 2

By "tool tray" I assume your teacher meant the Windows taskbar and by "to set-up" I assume he/she meant "to set up"1:
If you:
right-click the PowerShell icon in the taskbar, you get a shortcut menu,
in which you can right-click the first entry in the last section to edit the properties of the shortcut file that started the application:
The resulting dialog will show you the desired Start in: field, which determines that shortcut file's startup folder:
Enter the desired startup folder (C:\Users\Administrator\MyScripts in your case), and click OK.
To determine the shortcut file's own location, switch to the General tab of the dialog and inspect the Location: field.
If you haven't yet pinned PowerShell to your taskbar, the Location: field probably contains C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows PowerShell.
The shortcut file's own name is Windows PowerShell.lnk, though the .lnk extension is typically hidden.
In other words: by default, the shortcut file's full path is C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows PowerShell\Windows PowerShell.lnk.
In general, shortcut files (*.lnk) store properties such as executable location, startup folder, initial window state, and shortcut key.
As for what you've tried:
As Matt states in his answer, you've invoked the Properties dialog for the open PowerShell console window via its system menu (windows menu), which allows you to persistently change window properties, but not the startup folder.
1 "To set up" is a phrasal verb - no punctuation needed, and not to be confused with the noun derived from it, "setup".
