    Registry intro

    We all have heard of registry in windows and many modifications and that many actions should start from there. But what does the term registry , really mean?
    It is a small ,essential part of the windows OS ,that is responsible of keeping all necessary info about all the applications installed and running in the windows OS. Each application has a valid key ,that is used when it is "called" to function.But lets take the things from the beginning.

    Registry has four sub-parts ,that characterize its structure.

    Registry>Trees>Hives>Keys>Values. The functions and the information of each program are stored in a sub-category like this and create a value ,in there.

    This tree contains all hardware info about the computer and the network.

    Now these trees have as sub-categories some certain hives. For instance HKEY_LOCAL_MACHINE is aparted by
    The Hives can be stored in two points. Either in the Hard Drive or can be created in the memory each time the OS boots. The two files created for the hives are called registry file and log file. The first one contains all the real data for the registry and the log file just has all the modifications that have been made to these data.


    These are organizational units that can be used as index for your registry. There could be huge number of them in your system's registry. Their architecture is similar to your folders and files. They too are using a same calling symbol for the registry as your files do for the explorer of the system. Those keys are containing data ,values and subkeys which contain also subkeys and values and so on.

    Registry intro

    his is the foundation of the registry part and are specially designed to carry data for a specific API or procedure of windows OS. These values are divided in five basic types of categories.
    REG_DWORD some numeric data that have a 32 bits size
    REG_BINARY numeric data with various sizes.
    REG_EXPAND_SZ alphanumeric data forms of any size. They are modified by the use and the passing of time. They are usually responsible for system and application parameters.
    REG_MULTI_SZ same as above ,but now each alphanumeric char is separated from each other by the char NULL. This value is usually responsible for info about lists like the pull down menu.
    REG_SZ this contains an alphanumeric value ,with various sizes ,but stable. No changes are applied to them.

    Now that a simple explanation of the registry structure has been given ,we can proceed to the way it is used by your OS. The first time your registry is accessed is by the time your OS starts. After that the registry is under constant access by the windows and the changes to it are, too many to be counted.
    Modifications to it can be done by the use of control panel and its utilities or by just using a simple application in your computer.
    You can also use registry editor and do a manually change of the data in the registry.For win9x you can type regedit at the run prompt field ,for Windows NT,XP,W2K you can go to run
