Shutdown Collision Flaw

Over the summer, I discovered a design flaw in Microsoft’s Windows operating system which is both fun and allows you to use it for free.

When you install Windows without paying for a license key, there is a trial period, after which it will begin telling you to activate. But if you don’t, it will force your computer to shutdown every hour without letting you save your work. This is basically the only thing that actually stops you from using it normally. If it weren’t for this fact, no one would really have to pay to use Windows.

But it turns out that you can prevent this.

  1. Press Control + Escape or click the Start button to open the Start Menu or Start Screen.
  2. Type “Command Prompt”.
  3. Press Enter.
  4. Enter the following command: shutdown -s -t 600000
  5. Press Enter.

You can change the number at the end to whatever you prefer – it is a number of seconds.

What you are doing is initiating a shutdown sequence on a timer before Windows launches its own. Because two shutdowns cannot happen at once, you block it from being able to turn off your computer.

This is easy enough for non-technical people to follow. It requires no download and even non-administrator users can do it. There’s no setup or install, everything you need is already available on your system, just a few keys away.
