2 dos prompts available in XP

In Xp we have to different versions of DOS
1.command.com
2.cmd

type command.com or cmd in Run to lauch each version respectively.

command.com is earliest version and cmd is latest version
you may not get every facilities in older version.Eg if u want to execute previous command in cmd we use UpKey and we get all the previous commands.But this is not possible with command.com

Try them and you may get some more difference.But it is kept because some programs may still require old dos to run

hidden music file in xp

Yes,one more hidden facts
Windows xp has got a built-in music file which is played automatically when we format our system and reload windows xp.
But windows xp doesnot have builtin driver support for our audio device thats why we are not able to hear that sound.
Here is the place where that file is kept after installation

C:\WINDOWS\system32\oobe\images\title.mwa

The file is hidden,so from folder option check
show hidden files and folders and
uncheck hide system files and folders

Java Still not a Pure Object Oriented Programming Language

No doubt java is the popular object oriented language in market.But sorry to say its not pure object oriented programming language.

Reason:
Everything is not an object in java.Sun people kept primitive datatype like int,char,float which doesnot make java a pure object oriented language.Primitive datatype are kept to make program execution faster,as dealing with object is quite expensive than datatypes

If we develop our program using wrapper class only than we can say our program is following pure object oriented programming language

File where your XP accounts and passwords are stored

In windows xp,when ever we login,we have to provide a userid and password.The system will then try to match this parameter from a file where it has stored account info.So which is that file is the main Question?
c:\windows\system32\config\ SAM
Yes,SAM file contains the information.But we cannot copy and export or delete that file,it will show you the file is being accessed by some other process.System process is running behind the screen and it doesnot allows you to copy,delete or modify.
Even you cannot kill the system process,if u try to do ,you will get a system shutdown message with in a minute.and your system will be shutdown within 1 min(type shutdown -a in dos prompt to abort shutdown)

So can we know the password of the user.Yes we can use a tool called SAM Inside which can use BruteForce and Dictionary attack to get the password for us.
Dont try to copy SAM from Dos safe mode.still it will show you same message.

Good Luck

Exceptional Process

Guys,While experimenting with processes i found that SYSTEM IDLE PROCESS cannot be right-clicked,i means u cannot even try to kill it,or set its priority

  • open task manger and goto process tab
  • There you will find a lot of process running by many accounts
  • You can try to kill or set the priority of any process by right clicking it
  • But try for System Idle Process.You cannot even get the pop-up

Even i dont no why?Even Iam in the search of this answer.Now dont says that it may be a critical and very important process,thats why windows doesnot allow you to kill it.But what if we want to set it to high priority

One Click Shutdown

- Create a new shortcut, and type "shutdown -s -t 00" in it then put any name for the shortcut file. This way it saved. Now whenever u click the created shortcut file, your pc will turn off automatically.

Quickest way to shutdown Your computer

This is the quickest way to shutdown your computer.But i suggest you not to use frequently,as it is not a standard procedure.How ever in case of emergency you may find it helpful
  • Open Your TaskManager(ctrl+shift+esc) or (alt+ctrl+delete)
  • From shutdown just highlight TurnOff
  • hold ctrl key and click on TurnOff
  • Wait for only few second and Your computer is dead.I mean turned off
Shortcut:- ctrl+shift+esc , Alt+u, press down error twice, ctrl+enter
This works with win xp.If you have applied certain theams then ur shutdown option may be missing in Task Bar.
Remember it doesnot releases all your resources before closing the system.So try it in your own risk

On Renaming Recycle Bin

Rename Recycle Bin in different way

- Copy the following text on notepad

REGEDIT4

[HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder]
"Attributes"=hex:50,01,00,20

"CallForAttributes"=dword:00000000



- Now save this text file as a .reg file choosing 'Save as type' to 'any files', such as "davidcnovasax.reg" and put it wherever you like as your file name, it doesn't matter. Double click on the file, and when it asks you if you want to import it into the registry, choose Yes. You'll notice a new option in the right-click menu to Rename the Recycle Bin. You can also rename it by highlighing the Bin and hitting F2, or by highlighting it and clicking on the file name (just like renaming any other file.


If you want to turn off this new feature, make another .reg file with the

same content as above, but change the first number in the "Attributes"=hex:

line from 50 to 40 and import that file into the registry.
