For reference my test was on this 2-line .ps1 file -
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.MessageBox]::Show('Hello, World!')
#3 obviously I'm referring to basic to moderate tasks - VBScript is instant, powershell isn't on my test.
#1 this would be news to people on the web where I found people unable to find ways to run powerscript without the console, I checked to see if AI could find a way and it couldn't. Perhaps you can suggest how (or a reference)
#2 a launched .ps1 'hello world' popup (above) has a sluggist start with a large footprint; VBS is minimal. Maybe powershell is small without any module loaded but then maybe that is not an ordinary scenario where it needs user interaction, like saying a car is perfectly light without any engine.
However I will look into whether there's anything invisible in the launch that could reduce the considerations I mention...
