Currently Playing: I Found a Strange Windows Behavior That Shouldn’t Exist

In this video, I explore a strange and unexpected behavior in Windows PowerShell. While testing the built-in curl alias (which is actually Invoke-WebRequest), I discovered that it can execute JavaScript in ways that most people wouldn’t expect. I go step by step through my process: checking which window properties exist, testing functions like alert() and confirm(), and seeing how window.location behaves. For demonstration purposes, I show a small, safe loop that opens 5 browser tabs — nothing harmful, nothing destructive, just a proof-of-concept. Important Notes: This is educational only. I am not showing how to crash PCs, create malware, or exploit anyone. Normal web browsers like Chrome, Edge, and Firefox block multiple popups unless triggered by user interaction. This behavior is specific to PowerShell’s MSHTML host. Do not try to reproduce anything with harmful intent. The goal is to raise awareness of this unexpected behavior and highlight a potential design flaw in PowerShell. Takeaways: Always use curl.exe in PowerShell if you want predictable, safe behavior. Never run untrusted commands in PowerShell or any terminal. Being curious is good — but ethical exploration is better!
