How to Hide Application Icon in Windows 7 Taskbar

Microsoft Windows 7 comes with a taskbar that has never before been witnessed in its predecessors. The Windows 7 taskbar features a dock-type appearance and utility tools like launching a program or running an application. Undoubtedly, the Windows 7 taskbar helps the user to an extent more than what meets the eye.
Here, we unveil a new utilization feature of the Windows 7 taskbar. Often, some programs and shortcuts to various applications are pinned to the taskbar for easy accessibility. However, sometimes for reasons concerning privacy and confidentiality, the user may want to hide these icons so that other users logging into his computer do not have access to his private applications or programs. We’ll now plow on the process to achieve this useful tweak.
To start with, the icon that needs to be hidden should remain invisible at the taskbar with only the creator knowing its perfect location and the authority to view and access it. We, here, take Mozilla Firefox as an example to the program that requires to be hidden. On completing the following procedure, your taskbar will contain Mozilla Firefox as a launch up program while keeping it invisible to anyone who logs on to your computer.

Making a program icon invisible

To make a program icon invisible, you need to use software called “Resource Hacker”. Download this freewareto start the process. The downloaded file is a “.zip” file. No installation is required to use this software.
On extraction, locate the file “ResHacker.exe” in the extracted folder. Right click on this file and select to “Run as Administrator”. Confirm on request to open Resource Hacker.
1. After the software opens, go to “File” menu (or simply press Alt+F). Select “Open” and navigate to the location where the Mozilla Firefox execution file is present. (It should be in the folder “Mozilla Firefox” in the “Programs” folder of the directory where Mozilla is installed). Select the file “firefox.exe” file and click “Open”.
2. The Resource Hacker wizard opens up. Select “Icon” and then click on the “Action” tab on the menu-bar. Select “Replace Icon“.
3. The “Replace Icon in” window appears. Select “1″ in the right pane of the window under the tag “Select icon to replace” and then click to “Open file with new Icon…“.
4. Navigate to “C:\Windows\System32\” and click on “shell32.dll” to open it.
5. On clicking “Open” a list of icons appear under the tag “Select new icon“. Select the icon number 52. Then click to “Replace”.
You will be notified that the icon has been replaced.
To proceed, you have to replace a second set of icons. Select “Open” under “File” menu. On asking whether to save your work, select “NO“, as the task is not completed yet. Follow the steps 1 to 5 once again with the exception that in step 3, this time, Select “32512″ in the right pane of the window under the tag “Select icon to replace”. Follow the remaining steps as you have done previously.
Save the file you have just created by pressing Ctrl+S to the installed program folder of Mozilla Firefox (in the folder “Mozilla Firefox” in the “Programs” folder of the directory where Mozilla is installed).
Exit Resource Hacker.
The new file created “firefox.exe” can be visualized when you open the folder where Mozilla is installed. This file does not have an icon, or more technically, the icon of this file is invisible. The original Firefox execution file still remains within the folder with it being renamed to “firefox_original.exe”. Now, right click on the file “firefox.exe” and select “Pin to taskbar”.
To the right of the pinned programs on the taskbar, appears a section which, on hovering your mouse pointer over it, displays “firefox.exe – Shortcut”. You have just created a secret invisible icon in your Windows 7 taskbar. Drag this section to the extreme left of the taskbar to the right of the “Start” button.
Your taskbar remains just as it was before you created this invisible icon. None, but you know the exact location of this icon. Your privacy gets boosted up with an increased accessibility option.

Lock/Unlock Computer With Pendrive

SYSKEY is a utility that encrypts the hashed password information in a SAM database in a Windows system using a 128-bit encryption key.
SYSKEY was an optional feature added in Windows NT 4.0 SP3. It was meant to protect against offline password cracking attacks so that the SAM database would still be secure even if someone had a copy of it. However, in December 1999, a security team from Bind  View found a security hole in SYSKEY which indicates that a certain form of cryptanalytic attack is possible offline. A brute force attack then appeared to be possible.
Microsoft later collaborated with Bind View to issue a fix for the problem (dubbed the ‘Syskey Bug’) which appears to have been settled and SYSKEY has been pronounced secure enough to resist brute force attack.
According to Todd Sabin of the Bind View team RAZOR, the pre-RC3 versions of Windows 2000 were also affected.
So this is pretty cool, right?  Well, I really like the idea of keeping this on Floppy so that it requires a floppy disk (a sort of 2 factor (hardware/software) authentication?).
Naturally I wanted to go a bit further and use this on a USB drive instead of storing to a Floppy.  I can’t see myself carrying a floppy and a USB floppy drive around with me.  After all, this provides another layer of security.
NOTE:  I haven’t tested copying data from 1 USB to another USB to see if it works as a backup.  This way you could lock up a USB drive as a spare if needed.
Here’s how to get this to work using a USB drive.
1.  Insert your USB drive into your system and wait for it to be recognized and install any necessary drivers.
2.  Fire up disk management and re-assign the drive letter it was given to “A”.

Start up disk management by clicking Start and typing diskmgmt.msc


Right-click the USB drive and choose to assign driver letter or path.

Assign it to letter “A”

Accept the warning message

Now your USB drive is “A”

3.  Run Syskey and save encryption to USB Drive “A”

Click Start and type syskey followed by hitting Enter

Syskey launched; Click “Update”

Choose “Store Startup key on floppy disk” and click “OK”

You’ll be prompted to enter your diskette. Make sure your USB drive is inserted and writable.
4.  Reboot and have fun.  Don’t lose your USB disk!  Also, to revert this, you can run syskey again and choose to store it locally instead of “on a floppy disk”.

Internet Access In Backtrack Virtual Machine

I’ve found that some people are struggling hard to access internet in there backtrack virtual machine from their USB Modem, so today I am going to tell you how you can access internet in your virtual machine by your datacard.
