Windows XP Registry trick

Today I teach you some of the very interesting system registry editing tricks......
but try these tricks at your own risk....

First of all goto start>run
type regedit.exe

Structure of Windows XP Registry :

When you will open the Windows XP Registry, you will see it's divided into two panes.
On the left side there are Five main Keys as shown below. These can be expanded to
several Sub-Keys, which further has many Sub-Keys.
Before you try out the Tweaks, learn how to Backup and Restore Windows XP Registry.

Types of Registry Backups :

It?s very important that before you do editing you make a backup of the current registry. If you ignore this warning, it might prove deadly for you?so better listen to me
Open your registry:

Go to Start>Run,
type regedit.exe
When you invoke the Export function by clicking File>Export, you are given a choice of different file types that can be saved :

Registration Files (*.reg)
Registry Hive Files (*.*)
Text Files (*.txt)
Win9x/NT 4 Registration Files (*.reg)
All Files

Each one of the different file types above plays an important role in how the data you export is saved. Choosing the wrong type can give you unexpected results. So let me explain you quickly these file types.

Registrations Files:

The Registration Files option creates a .reg file. This is the most well known file format used for backing up the registry.The Registration File can be used in two ways. As a text file it can be read and edited using Notepad outside of Registry Editor. Once the changes have been made and saved, right clicking the file and using the [Merge] command adds the changed file back into the registry. If you make additions to the registry using regedit and then merge the previously saved Registration File, anything that you've added via regedit will not be removed, but changes you make to data using regedit that previously existed in the saved Registration File will be overwritten when it is merged

Registry Hive Files :

Unlike the Registration Files option above, the Registry Hive Files option creates a binary image of the selected registry key. The image file is not editable via Notepad nor can you view its contents using a text editor. However, what the Registry Hive Files format does is create an image perfect view of the selected key and allow you to import it back into the registry to insure any problematic changes you made are eliminated.

Text Files :

This option does just as the name suggests. It creates a text file containing the information in the selected key. It's most useful purpose is creating a record or snapshot of a key at a particular point in time that you can refer back to if necessary. It cannot be merged back into the registry like a Registration File.

Win9x/NT 4 Registration Files :

This option creates a .reg file in the same manner used by the Registration Files option. It's used by previous Windows versions and serves no purpose in XP unless you want to merge a key from XP into a previous version of Windows.

Out of the give above choices , the safest method of backing up registry is to use Registry Hive Files option. No matter what ever you do or goes wrong in editing, importing the image of the key will eliminate all changes.

1. Disable the Autorun Option in your CD Rom Drive:
Open your Registry and navigate to "HK_L_M\system\currentcontrolset\services\cdro m" Change the value of 'Autorun', or create a new DWORD value if it doesn't already exist, and set the value as '0' for Autorun disabled.
