How to Crash Windows XP

So where do we get stdio.h ...?

Not a C programmer then, are you? 8)

I crashes win 2k also

Finally someone made useful software for a WinXP (goddamnit its ugly and unuseful)

he's so dumb... GO GET stdio.h at your nearest drug store... =), ask for a conio.h too

My XP crashes all the time. At least once a day. No fun at all.

Been there, done that.
almost as funny as the F00FC7C8 trick :-)

Your code did not crash my computer running Windows XP. But if I set it to loop forever it will sooner or later, sometimes after a minute, and sometimes it will last 30 minutes before it crashes.

what's the F00FC7C8 trick? and yes, i'm a c programmer

Greetings,

F00F was basically an undocumented instruction that could be executed in usermode code that would lock the processor. Do a Google search for 'F00F Pentium bug' and read up on it.

Did the same test on linux. Nothing Happened. preforming loop test. nothing so far. CPU pegged but system still responding. im curious what the real problem is? too bad i can't look at src to find out.

the problem is that when you do it in Windows, the console reads those backspaces, and it backspaces so far that it's not even on the screen anymore. Then when it tries to print text, it's printing off-screen, and therefore outside of its memory allocation. Windows thinks that this means the system is unrecoverable, so it deliberately crashes itself.

I found this info on www.zappadoodle.com, which was referred to me by a friend on an IRC channel.

darn, I thought more people would come here

I and others wrote a little longer explanation on this, it is on :

I've got a question about crashing windows xp.
the commands.... Must i write it in program and in what programming language??

can n-e of u tell me how 2 use these codes in a website.... i'm not a programmer... i'm a webdesigner... i would like 2 design a website that would crash XP. http://www.cyberarmy.com/crash.shtml didn't do the trick.... and it's offline now n-e-way.

The F00F bug was NOT an undocumented instruction. For people that pretend to know what you're talking about, you guys don't even bother to check the most obvious places for information. Like Dr. Dobb's journal. The bug stemmed from the fact that for some reason, using the LOCK prefix on the register-based CMPXCHG8B EAX instruction was ALLOWED. In a working system, this would generate an invalid opcode exception, because LOCK prefixes are only allowed on memory-based read-modify-write instructions. When the processor issues the bus reads to get the #UD handler vector address, the processor erroneously asserts the LOCK# signal. Also, the bug is not limited to F0 0F C7 C8, but also every other instruction up to and including F0 0F C7 CF. Of course, if any of you had a fucking clue, you'd know this.

hey how can i get some windows xp user to crash from irc? i want to do that.
cant i type something to do it like the con/con thing?
for those who dont know how this is how
/ctcp sound IFS$HLP$/IFS$HLP$.mp3
and if they got win9x theill crash! but email me if u find a way to crash windows xp trew
a irc command or sumthin

i need to know how to crash windows ME! any help? thanx

You guys are ridiculous. Don't you have a life? I guess: NOT!
I don't know why this is a big deal. It's just a huge sign of very poor programming skills from your side. Every respectable programmer knows what NOT to do, which includes writting characters in unusable space.

lololollolloloLZ!!~!~!~1`!

I am a true-blue aussie mac user... and i find many ways to crash windows.. hehehe... but how do you work this? HTML? JAVA? Or just the DOS prompt?

It's a bug in the command prompt program. (the console reads those backspaces, and it backspaces so far that it's not even on the screen anymore. Then when it tries to print text, it's printing off-screen, and therefore outside of its memory allocation. Windows thinks that this means the system is unrecoverable, so it deliberately crashes itself.)

Another way to crash Windows
XP is to go into the BIOS of your computer and enable all shadowing. Reboot your computer and watch Windows XP.

If anyone knows the commands in VBS to crash windows xp from a website, please email them to me. I want the script to be executed when the webpage is loaded without anyone knowing. :-)

I am wondering....I am starting to get more into computer programming and out of Music Producing. I want to know How/Where to use the Windows XP crash. Im not at all in a sence on how to use that.

Please reply!(E-Mail)

how do can i send someone something to crash windows xp ? or what site can i go to to get one ?

You can use many techniques to crash windows, even having them go to a certain webpage with executable sourcecode from the site can log off Windows users. But keep in mind its not what your code looks like, its if you succeed.

windows xp is based in windows
NT ,meaning that any user program cannot access kernel space (PRIVILEGE LEVEL 0 or Ring 0).Any user program runs with privilege level 3,and so less privilege.Sometimes there are ways to acces PL 0 and enter kernel space and consequently crash your computer and a lot more things:).Old MSDOS didnt had this technology so,you could access its memory space and crash it.Windows xp runs in whats so called Protected Mode
and Dos ,Real Mode.If you want to understand ore about this check this link http://www.deinmeister.de/x86modfd.htm

I think that the code posted is a c code, but i cant compile it as is. I am a c++ programer. Can someone explain what to do with this?
Also when i put it in the command prompt it says "was unexpected at this time."

This is so fucking lame, #include <stdio.h>

void main(void)
{
    for(int i = 0; i < 5 ; i++) printf("\t\t\b\b\b");
} all it does it plays some sounds...

i am the f word and will take over the world

hey i was wundering if you guys could tell me a way to crash windows 2000 or xp with something like a web site script or like the old way of C:/con/con (works on windows 98 or lower) please e-mail me with anyways thanks

Alright.. i just got the blaster worm virus and i want to crash my computer so that best buy will give me a new one for free under warantee. I know absolutely nothing about this type of thing. I have read all the comments on this page and i don't really understand any of them. Could someone please post step by step instructions to crash my windows xp. Also, is this traceable? Is it possible that the people at bestbuy could find out that I purposely crashed my system.

Please post the instructions.. the email is obvioulsy false.

how are you supposed to appyly the code at the top of the page to crash an xp computer? like, do u turn it into an exe or what?

I need to crash a website how do i do that?

Wanna crash windows?

This page is magic, Chris; you seem to have tapped some sort of 3r33t hax0r mother-lode. I especially enjoyed the insight from the C++ programmer. For more info on this bug see http://homepages.tesco.net/~J.deBoynePollard/FGA/csrss-backspace-bug.html

rock on!

i recently designed a website, and realized that it failed to elicit a public response. therefore, i would like to crash it, NOW! how can i do this?

I'm pissed off at the world, and I just got a new car, and I'd like to commit insurance fraud and crash it just so that I can get some money to buy more weed. Does anybody know how to do this?

Oh, and I only know C++, so please teach me C because I'm an IDIOT!

And I can't get enough porn of IRC, so I want to crash that too, any ideas?

While we're at it, anybody know how to crash the Internet?

Be real clear when you tell me, too, because I'm a MAC user from down under and I don't get this whole "command line" stuff.

By the way, since you read this whole web page, your computer will now crash!

So will your TV and your microwave.

And your toaster.

I want to crash systems having win 95 and 98, pls gimme some tips. pls email me on vene_rable@yahoo.com

Whell.. the way s to crash a win 95 and 98 are very easy... are many ways to do thath..

This are a few what i know...

the clasic: BUG "CON" is very easy..

just put this in the dos:

C:\edit c:\con\con

and this crash win 9X

you can change con for "aux" and other thinks...

---- other...

you most to run this in the debug from dos:

-DEBUG
-a100
-cli
-jmp 100
-g

(try doing in..a copy of choice.com ja ja! a crash program)

make a copy of choice.com... in the desktop

-DEBUG choice.com
-a100
-cli
-jmp 100
-w
-q
exit

and thath.. crash Win 95 and win 98.. and more thinks like blue screens and crash ways but if you want to know more.. email me

PD:"Yes! i speak spanish sorry! :X"

ATT:ALEX.

Can some one email me a code to crash xp ect with a web page. I have found a code in VBS but it dosent work on any computers i have tryed.

another form very simple to crashear xp:

--->
:X
start %0
goto X
--->
all this in a batch file...

PD:"that is all friends"

ATT:ALEX.

If you want to really crash Windows XP, use the following data.

4D5A0000504500004C010000000000000000
000000000000E0000F010B01000000000000
00000000000000005001FF34F000FF34F000
FF3400004000040000000400000004000000
000000000400000000000000DC02FF340000
FF34000000000200

It's an executable PE file. (98 byte)
The DOS STUB has been removed and the PE header starts right after DOS MZ. 3Ch will of course have the e_lfanew (PE header offset), which in this case is 04h. This is as you can see, basic stuff. The more fun part begins when we start to play with the PE structure. It should be very obvious what's going on.

Enjoy, crashing your own WinXP!

thanks iqlord.
how do u make an exe file outta that?
Whats a PE file anyways?
Thanks

Thanks guys i hope that this works i ma not really a teacher but i am the best hacker in my school so me and a team of three are going to drop two or three networks consisting of like 144 computer in the school if these dont work than ill be back for more plans because we dont have the means to build a worm or virus so if one of you guys want to have a part in this than email me with plans teachermmcs@yahoo.com.

thanks guys keep me posted on ne thing new

Go into macontosh hd and delete the files and change the numbers in the exe file.

I would have to say, the comment by "Dumbest_One_Here" was the best.

I give it two thumbs up!

If you really don't like your windows computers, buy a hammer... or maybe a stick of dynomite might do the job.

Then build a linux box :)

Ok, i'm sorry i've been reading this post i have a computer that i've basically jacked from work but of course now i don't have the administrator passwords. I want to erase the entire system clean and then re-load the programs on it. Can someone e-mail me and let me know how and what to do? I'm not very computer literate here and i know a lot of you are very smart.

thanks

Damon

I think the best solution is to just shit on my keyboard. Like this one time at computer camp, i stuck my motherboard up...
Fuck yall bitches in the ass knee egg gras. (you female niggs)

somebody come lick my balls

fuck all you computer geeks
