By default, double-clicking on the "ps1" files (PowerShell scripts) will open notepad.exe.
It's secure at some level, but is a little inconvenient in some cases.
The following tip enables you to run PowerShell script files with the double-click action, even without changing the "ExecutionPolicy".
A side effect of this technique is that you can no longer pass the command-line argument to the script.
1. Give a PowerShell script file the extension ".cmd" or ".bat".
2. In the first line of the script, place the following code:@{}# 2>nul& PowerShell.exe -Command - <"%0" &goto:eof
