Difference between 32-bit and 64-bit operating system

There are two main things to keep in mind when choosing between a 32-bit OS and a 64-bit OS: memory support and software compatibility. There are others, of course, but those the two most important.
Typically 32-bit operating systems can only support up to 4 gigabytes of memory, while a 64-bit OS can theoretically support upwards of billions of gigabytes. 64-bit operating systems are limited by artificial software and hardware ceilings, but the ceilings are still much higher than a 32-bit OS. So the short answer for memory support is this: if you want more than 4 gigs of memory, you’ll need a 64-bit OS.

Software compatibility is the other thing to keep in mind, and the more important, in my opinion. Some software that runs on a 32-bit OS will not run on a 64-bit OS, especially older software. Most modern software will run on both 32-bit and 64-bit, but checking your software before you upgrade is the only way to know. A little Googling can usually answer that question for you.

When making your choice, the bottom line is this: if you must have more memory than 4 gigs, go with a 64-bit OS. If you don’t need that much, sticking with a 32-bit OS at this point in the game is a decent choice, if only to ensure that your old software will keep on keepin’ on.

How to Hack Windows XP Login Password Without Any Software ?

Passwords can be describes as a verification tool for a object. Passwords are used to ensure legal or proper access to only those people who have the necessary authority or the permission. In this tutorial I will show you how you can change or remove the Windows XP login password without using kind type of software or password cracker. There are three methods for performing this hack. In the first two methods you can changer/remove the password without logging into any account, and in the third method if you are having a account on a computer and want to reset the password of other account you can use the last method.

First Method-

In the first method, when the computer boots press F8 key repeatatly until you get WINDOWS ADVANCE BOOT MENU, 
When this menu comes. Look for the third option called Safe Mode with Command Prompt, Select this option and hit enter. Wait for sometimes until you get the Comman Prompt on your screen. When the command prompt windows it opened in front of you type
"net user" (without quotes)   /* This will give you the name of accounts which are present on the computer */

Now type    net user "you username here" new password
Suppose you username is Almas and want the password hacker, you will type
net user "almas" hacker      (and hit enter)
You will get a message Command Successful, whch means the account's password is changed sucessfully.. In case you get an error, this means that you don't have the administrator privileges to change the password.

Second Method-
Now, in the second method when you get the windows login screen were you enter your account password. 
Press ALT+CTRL+Del two times, you will get a small window which will ask you for the user name and the password, in the user name feild type ADMINISTRATOR and leave the password felid blank and hit enter. You will be logged on as administrator
(this account is temprory ,after you log out that account will disappear). Now from that account you can change the password of any other account without any problem.

Third Method-
In the third method log in into your account, open run box and type CONTROL USERPASSWORDS2 and hit enter. There you will get the list of accounts which are currently created on your computer select and account and change
the password.

How Can I Recover Data from a Dead or Erased Hard Drive

I have a hard drive with valuable information on it, but I can't seem to access it—the drive is either damaged or erased. Is there any way I can see what's on the drive and get it off?

Sincerely,
Dear Paramedic,

Don't worry, we're not going to ask where you got the drive, but there are plenty of ways to examine it and see if any of the data is recoverable. With a little time, the right tools, and some care, you may be able to get some data off of that drive.

Step One: Assemble Your Tools and Examine The Drive's Condition

Full sizehttp://skyhacking.blogspot.com/2012/10/how-can-i-recover-data-from-dead-or.html

The first thing to do is make sure you have the tools required to connect this drive to another computer safely. Ideally, you'll have some kind of SATA/IDE to USB cable orUSB drive enclosure or sled that you can mount the drive into and connect it to your computer easily. Sure, if you have a desktop and like getting your hands dirty you can try to install the drive as an internal one, but an external connection is faster and easier.

Next, take a look at the drive itself. Is it damaged in any way? Are the pins bent or broken? Make sure that the drive is in good enough condition to actually use before you try anything in the first place that may damage it even further. If the drive is too physically damaged to attempt recovery, you may need more drastic measures that we'll get to later. If everything looks good and you have the equipment required to connect the drive to your system, we can proceed.

Step Two: Grab Some Data Recovery Software and Connect the Drive

Before you do much else, make sure your antivirus and antimalware tools are up to date. You don't know what you'll find on this drive, and you don't want it to start misbehaving once the drive is connected to an active system. Once you've done that, it's time to download and install some data recovery tools. Here are a few we love:

• Full sizehttp://skyhacking.blogspot.com/2012/10/how-can-i-recover-data-from-dead-or.html

  
    Recuva (Windows, Free): Personally, Recuva has been indispensible. Made by the same folks behind CCleaner, Recuva makes data recovery simple and easy. if you're only interested in browsing and restoring selected files off of the drive, Recuva is a great option. Alternatively, check out Undelete Plus for Windows.
• FileSalvage (OS X, $80): File Salvage for Mac will set you back some serious coin, but it's one of the best tools to pull data off of a connected hard drive in OS X. It can recover virtually any type of file on multiple partition types, and prides itself on its ability to recover from damaged drives and corrupt media. If you want an alternative, try Data Rescue for Mac ($100).
• TestDisk (Win/OS X/Linux, Free): If you're not afraid of the command line, TestDisk is an open source utility that can run against almost any platform or partition type. It does a great job of recovering data quickly, and won't do unnecessary writes against the drive you're trying to recover from.
• Full sizehttp://skyhacking.blogspot.com/2012/10/how-can-i-recover-data-from-dead-or.html

  
  Bootable Linux distros for drive recovery: If you're not interested in messing around with apps (or paying for them), consider burning a bootable CD or USB key with BackTrack, Bart PE, or SpinRite on it, so you can boot to an OS that's not your primary drive, avoid writing or touching the drive you want to recover from, and run a host of recovery and forensics tools against that drive that are highly effective and completely free. Photo by Roman Soto.

A number of these tools can recover from formatted drives, especially if the data hasn't been overwritten. We've tackled this topic before, and used Knoppix as our bootable linux distro, but the steps apply to the ones we've mentioned as well. For more reading, check out this old but still largely accurate guide at Linux.com to recovering from formatted drives.

Remember, the less you work with the drive you want to recover data from, the better. As you read from the drive, you run the risk of exacerbating any damage it may have. The more you write to the drive, the more likely you are to overwrite something you want to recover. Bootable linux distros—many of which have tools like TestDisk pre-installed (among other, more advanced tools)—are the best way to go if you're familiar with the method and if you're interested in recovering entire partitions, or making a non-bootable drive bootable again. If you're just looking for files and you know the drive was in a Windows system or a Mac, a stand-alone app is an easier way to go.

Step Three: Get Out the Big Guns (and Your Wallet)

Full sizehttp://skyhacking.blogspot.com/2012/10/how-can-i-recover-data-from-dead-or.html

Okay, so the drive is physically damaged, has been wiped and overwritten, or nothing else you try works and you really, really need the data off of it. You're even willing to pay a lotfor it. We're not going to ask why, but at this point it's time to call in the professionals.Photo by Glenn Fleishman.

Pick up the phone and call the folks atDriveSavers and OnTrack to see what they can do for you. I've had good experiences with OnTrack. DriveSavers is well known and loved, both because they came to the rescue with free drive recovery services after September 11, 2001 and more recently helping Wired's Mat Honan recover from his epic hacking. Both companies do a superb job at pulling data even off of drives that have been formatted, overwritten, or even severely physically damaged. Keep in mind though that these services generally run in the tens of thousands of dollars and higher.

---

If the drive is yours, or the data you get from the drive is valuable, we'd strongly suggest youmake sure your data is backed up, both locally and online. After all, it's better to be able to get the data back quickly than have to jump through these hoops every time a drive fails. Remember, every hard drive will fail eventually, it's just a matter of time. Now go forth, use this knowledge for good, and recover!

REMOTELY SHUTDOWN OTHER COMPUTERS

Things you should know before you begin:

-You NEED a computer
-You NEED a friend’s computer
-You NEED a pencil/pen and paper or a really good memory
-This only works if both computers are on the SAME network (i.e. computer labs at school)
HOW TO REMOTELY SHUTDOWN OTHER’S COMPUTERS

Before I start I want to make sure that anyone reading this guide understands that you MUST be on the same network as the computer you are trying to shutdown. This means that you can’t do it to a friend who lives next door, and most of the time it wont even work on to a computer in your house. However you may be able do this to computers on an office floor, or in a computer room/lab at school or the library.

Step 1:

First off, you will need to find the computer name of your targeted computer (this is the person you will be turning off).

To do this, you need to get to their computer somehow (sorry I don’t have a guide on sucking up or invisibility). I suggest you wait until they go to the restroom or look away for a second (you'll only need to be on their computer for about 15 seconds or less). After you get on their computer you need to click ‘start,’ then right click on ‘my computer.’ Here you will see a little list, of which at the bottom will be ‘properties.’ Click ‘properties.’


After clicking ‘properties,’ look on the ‘computer name’ tab for the ‘full computer name.’ WRITE IT DOWN (another smart idea to shorten the time you're on their computer is to take a picture of it using your cell phone). Generally it will be something with some numbers and the word ‘YOUR’ in it. That’s always the default computer name and remains unchanged for most computers.

Now you're all done on their computer. Make sure you put the screen back to how they left it so they don't think something is up.
Step 2:

Now go back to your computer. Click ‘start,’ then click ‘run’ (bottom left, under 'search').


After the ‘run’ screen opens it should look like this:


Now type ‘CMD’ into the box provided and click 'OK.' Now this window should pop up:


When it opens type ‘shutdown/i’ and this window will open:

All you have to do now is click ‘add’ and type the name of the computer that you wrote down (or took a picture of) earlier (I suggest that you practice on yourself the first time then cancel the shutdown, see extra tips). You can also change the shutdown delay and even write a little message to the person you are shutting down in the 'comment' box. Try using a fun one like 'Your computer has been infected with an unknown device and needs to delete all open files.' That should really freak someone out who has a report or something important on the screen.

How to Enable Registry disabled by Administrator

ello friends, today i will explain you the solution of very common problem that usually users face i.e whenever you try to open registry editor you get an error message "Registry has been disabled by Your Administrator". It's a very common problem and its solution is also quite simple if you knowplaying with registry. My main motive is not to provide or directly feed you the solution. I want that you should explore the things. So Let's explore the registry... 

Enable Registry Disabled by Administrator

 

What is Registry?

The Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems. It contains settings for low-level operating system components as well as the applications running on the platform: the kernel, device drivers, services, SAM, user interface and third party applications all make use of the registry. The registry also provides a means to access counters for profiling system performance.

I know most of you know that registry is called the "BRAIN OF WINDOWS" which store all the information in form of registry keys or technically we call them DWORD or STRING or BINARY or MULTI-STRING values which stores the data into the data in the form the name suggests. 

How to enable the Registry disabled by Administrator?

The following message usually displayed when your system is infected by some virus that changes the registry value and hence you get an error message displaying " Registry is disable by Admin". So to fix it you also have to edit the registry but since your registry has been disabled so you cannot directly access it. For this you need to create one registry file that will update the dword value into the registry database.

Steps to enable registry:

1. Open the Notepad.

2. Copy the below code and paste into the notepad.

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools"=dword:00000000

3. Now save the Notepad file as "anything.reg"(without quotes) and remember to select the file typeas all files while saving otherwise you will not been able to execute it.

4. Now Close the file and open by double click on file and then click ok.

How to Do it using GPEDIT.MSC

Just follow this:
Start -> Run -> gpedit.msc -> User Configuration -> Administrative Templates -> System -> Prevent access to registry editing tools -> Right Click Properties -> Disabled

That's all the simple hack to Enable the Registry disabled by Administrator. Isn't that simple...
