Windows Registry Guide
Just some words about Windows registry
_____The Windows Registry is a database which stores critical settings and options for Microsoft Windows operating systems, and help the system administrators to manage better one PC station.
_____It contains information and settings for hardware, operating system software, most non-operating system software, network and per-user settings. Windows Registry offer a path to use and manage etire resources of one system. With the Registry you can control how the resources are used and who can have access on they.
_____A lot of security problems can be resolved with Windows Registry, you can easely to allow or interdict the access on the sistem resources (hardware or software resources).
_____The Registry replace the most part of *.ini files, used to configurate the systems in the earlier version of Windows or MS-DOS, such as Autoexec.bat and Config.sys.
_____Today exists some versions of the Registry, with some diferences between they.
_____When we talk about Registry, we need to understand two basic elements: keys and values.
_____Each key has a name consisting of one or more printable characters. Key names are not case sensitive. Key names cannot include the backslash character (\), but any other printable character can be used. Value names and data can include the backslash character.
_____The name of each subkey is unique with respect to the key that is immediately above it in the hierarchy. Key names are not localized into other languages, although values may be.
_____Registry Keys are similar to folders - in addition to values, each key can contain subkeys, which may contain further subkeys, and so on. Keys are referenced with a syntax similar to Windows' path names, using backslashes to indicate levels of hierarchy. E.g. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows refers to the subkey "Windows" of the subkey "Microsoft" of the subkey "Software" of the HKEY_LOCAL_MACHINE key.
_____Registry Values are name/data pairs stored within keys. Values are referenced separately from keys. Value names can contain backslashes but doing so makes them difficult to distinguish from their key paths. The Windows API functions that query and manipulate registry values take value names separately from the key path and/or handle that identifies the parent key. _____Each value consists of a value name and its associated data.
_____A registry tree can be 512 levels deep. You can create up to 32 levels at a time through a single registry API call.
_____Ordinarily, you do not need to make changes to the registry. The registry contains complex system information that is vital to your computer, and an incorrect change to your computer's registry could render your computer inoperable. However, a corrupt registry file might require changes.
_____We strongly recommended that you back up the registry before making any changes and that you only change values in the registry that you understand or have been instructed to change.
_____You must be logged on as an administrator to perform these steps. If you are not logged in as an administrator, you can only change settings that apply to your user account.
_____Before you make changes to a registry key or subkey, we recommend that you export, or make a backup copy of, the key or subkey. You can save the backup copy to a location you specify, such as a folder on your hard disk or a removable storage device. If you make changes that you want to undo, you can import the backup copy.
_____Prior editing the registry, it's a good idea to create a Restore point using System Restore. The restore point contains information about the registry, and you can use the restore point to undo changes to your system. System Restore helps you restore your computer's system files to an earlier point in time. It's a way to undo system changes to your computer without affecting your personal files, such as e-mail, documents, or photos. System Restore is not intended for backing up personal files, so it cannot help you recover a personal file that has been deleted or damaged. You should regularly back up your personal files and important data using a backup program.
_____Every time when you turn off your computer off and Windows shuts down successfully, important system settings are saved in the registry. You can use those settings to start your computer if a problem occurs. For example, if a new driver for your video card is causing problems, or an incorrect registry setting is preventing Windows from starting correctly, you can restart your computer using Last Known Good Configuration.
