A: For some actions to work in Windows PowerShell, your PowerShell session must be running elevated, so it has full administrative rights. If your PowerShell window is running elevated, the word "Administrator:" should be at the start of the title bar. You can also run the command below, which will return true if you are running elevated: <code>(whoami /all | select-string S-1-16-12288) -ne $null</code>

For example, I entered it and received this response, showing my session is running elevated:

PS C:\Windows\system32> (whoami /all | select-string S-1-16-12288) -ne $null<br>
True
