PowerShell的ExecutionPolicy和WindowStyle没用吗？

Question

I have a simple PowerShell script (1 line) in a lnk/shortcut :

%windir%\SysWOW64\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -WindowStyle hidden;cp file.jpg %temp%\file.jpg

Here are my questions :

1. I don't understand the utility of the parameters -ExecutionPolicy and -WindowStyle because no matter I write them or not it doesn't change anything. The script works without showing any prompt. When I run a .ps1 file I must use -ExecutionPolicy Unrestricted but here in my case I don't need -ExecutionPolicy ?

2. Is there a way to replace -ExecutionPolicy Bypass by /Bypass only?

Answer 1

That's a legit question:

• powershell.exe –ExecutionPolicy Bypass and it will start a PowerShell session that allows for running scripts and keeps the lowered permissions isolated to the currently running process. See MSDN .

• powershell.exe -windowstyle hidden hides the PowerShell application window after it has been created by the OS when the process starts. This means the powershell.exe code that processes -WindowStyle Hidden is therefore executed after the console window is opened, and the Powershell window is shown briefly .

In general, powershell.exe -NoProfile -ExecutionPolicy ByPass -File my.ps1 is how production scripts should be launched safely.

Enter powershell.exe /? and the PS prompt to show the built-in help of the available PowerShell command-line arguments.
