How to hack your own computer

How to hack your own computer (or make registry changes to customize your experience)



Delve beneath the bonnet of Microsoft Windows and you'll find powerful customization options. The key is accessing the registry – the operating system's engine room – via the registry editor. Click Start, then Run, enter regedit.exe and press Enter.
The registry editor is a powerful piece of software that provides full control over the operating system, so be careful. But if you want to customize Windows to make it your own, there’s no better way to do it. These top five tweaks from IT support company Conosco will help you get started.
Easily encrypt and decrypt your files
Windows Vista and 7 allow you to protect data with encryption tools, but these are hard to find. This hack makes them more accessible. In the registry editor, locate the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced registry key, then right-click in the right-hand pane and create a 32-bit DWORD value called EncryptionContextMenu. Give it a value of 1. Now, whenever you right-click on a file, you'll find encryption options as standard.
Add an application to the right-click desktop menu
Scroll down to the HKEY_CLASSES_ROOT\Directory\Background\shell registry key. Create a sub-key with the name of your chosen application e.g. Notepad, then create a sub-key underneath this one called Command. Locate the application you want to launch on your hard drive and copy the full path e.g. C:\Windows\System 32\notepad.exe. Back in the registry, left-click on the Command key, double-click the (Default) text that appears in the right-hand pane, and paste the application path into the box. Your application will now appear when you right-click on the desktop.
Display a start-up message


This is a cool hack, allowing you to display a custom message when the computer boots. Find the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced key and double-click on legalnoticecaption. Enter the headline of your start-up message, then click OK and double-click on legalnoticetext. Add your message and click OK. The message will appear the next time you restart your computer.
Disable pop-up notifications
This tweak will disable all bubble notifications that pop up near the system clock. Make sure you keep your system – including anti-virus programs - up to date, as your computer will no longer offer reminders. Open the registry, locate the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced key and set the EnableBalloonTips value to 0. To reverse the tweak, change the value back to 1.
Stop Windows Update from rebooting your computer
Sometimes Windows Update gets mad and announces it's going to reboot the computer. This can be frustrating if you're right in the middle of something. To disable this option, locate the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU key and create a new 32-bit DWORD in the right-hand pane called NoAutoRebootWithLoggedOnUsers. Give it a value of 1. This will prevent automatic restart when the computer is being used. To put things back to normal, delete the DWORD you created.

Network location settings vanish after restart / reboot

This is all in windows 7 . I've been trying to connect two PCs with a network card in a LAN. I want to connect them offline i.e not through modem / router. So in order to make connection working, we should set the network location to Home.
  1. If you already know how to setup LAN, skip this step and goto step 2. Otherwise, continue reading. Open Network and Sharing Center --> Choose homegroup and sharing options. If you've already created a homegroup on some other system, it displays a " Join Now " button. Else, you'll have a button to " Create a new homegroup ". Before this, you need to select network location to " HOME " by clicking on " what is network location ? " hyperlink. Do the same to other system too. If already home group is created , Join it. After checking your connectivity, goto next step
  2. Sometimes, this network location changes to public after rebooting the system / PC . In order to retain those settings, following changes have to be applied.
    • Open run by pressing " windows button + R "
    • Type " services.msc " without quotes and hit enter
    • Check the services named " Peer Name Resolution Protocol " , " Peer Networking Grouping ", " Peer Networking Identity Manager " and " Homegroup Listener ", " Homegroup Provider "
    • All these five should be set to either Automatic or Manual.
    • Make sure that all the above five were started
Now reboot  your PCs and check that your changes retained.
If any problem encounters while setting up a LAN, please comment below

Change Key functionality in windows | Remapping


We can actually change the keys functionality of each and every key in either Windows or Linux. This is called Remapping. In this post I will discuss about the Windows Remapping. 


There are 3 ways. 

1) The direct way of remapping keys in Windows is to use the Windows Registry.

HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Control\Keyboard Layout 

Disadvantage : User need scan codes to change a key’s functionality.

2) Alternate method is using remap software. 

Advantages : Visual representation of the keyboard, Scan codes not required.

3) Sharp Keys supports 104 keys that can be remapped on the computer keyboard. Sharp Key uses the native Windows functionality to remap the keys. This means that the software does not have to be running in the background after the changes have been made. Remapped keys on the keyboard can be deleted all the time which will write the original information to the Windows Registry again.

We have many utility tools for remapping. Some of them are MapKeyboard, KeyTweak etc,.

How to open/close ports in Windows 7 Firewall

 I've posted about the types of firewalls in my previous post. To know about the types of firewalls, Go here


Let us see how we can open ports on windows firewall.

In this post I wanna share how to open / close ports in Windows7. In my next 
Step 1 - Go to control panel, Click on windows firewall. Click on Advanced settings.
Step 2 - On the left side you will see two options , Inbound rules and outbound rules.
Step 3 - In order to open a port, Right click on Inbound rules and create new rule.

Step 4 - Select "Port" and click next
Step 5 - Now Choose the port type as either TCP or UDP and choose a port number. For example chose UDP and port number 12345.
Step 6 - Now choose connectivity type. It is recommended that you select all three options so that the port appears open even when you are not connected to any public network.
Step 7 - Now give a name to your rule. Click next to finish the process. You will notice that your newely created rule is now added in the rule list.
Step 8 - So your port is now open to receive connections. Right click on the rule and clicking on Delete will delete the rule and thus close the port.
But what to do after the port is open. Let us try to run a service over it.
Step 9 - Suppose you want to run a service on the port you just opened then the process is simple. Right click on the newely created rule, click on properties, then go to "Programs and services" tab.
Step 10 - You will have an option to add a service to the perticular open port.


Logs :


There is another important thing that security professionals will find helpful is viewing the firewall log file. It is an asset to determine network activities.
To view and configure firewall log file, open firewall, click on advanced settings, choose "monitoring".In the middle pane you will find an option of "logging" .

You can find your firewall log file and also other configurations there.

Note : If you are unclear and want me to provide screen shots, please let me know through your valuable comments.

Cameyo with free software, we can make software to be portable. Making Cameyo portable applications with very easy, we just need to install software as usual and run a few steps with Cameyo. Here are more details steps:
