In Windows, the registry contains the configuration data of everything that makes the system work. The registry is the heart and soul of Windows based operating systems. Each application that run under that environment does not do absolutely nothing without consulting it.
The Windows registry is accessed hundreds of times per second !
So, to keep your computer in a safe condition, fast, avoiding deadlocks and crashes you must maintain periodically this vital part of the system with a top quality trusted computer software.
The Windows registry. One of the most delicate and sensitive aspects of the Windows operating system that is often unknown by the users. This fundamental piece of the system is a compendium that contains information about the configuration of the computer, the drivers that allow the computer communicate with the peripherals, the software installed, the preferences of configuration of each logged user etc.
The registry can be a irrelevant and unknown piece of your computer until it begins to fail. Then your computer will become slow, its operation shall be erratic and unstable and you may lose the precious information that you store there. If you have come to that end or if you want to prevent such a situation you must clean periodically the registry with specialized tools created for this purpose. Correct or edit the registry is a really complex matter if you are not an expert on the subject; otherwise it is better entrust the task to a specialized program, which reviewed the thousands of keys to this file and attach the loose that hinder the proper functioning of the system.
Of the many programs available on the market we have done a ranking with the best, the more professional, that give us the security and the confidence that safeguard the integrity of the data and eliminate the sources of error in the computer.
The registry contains two basic elements: keys and values.
The structure of the Windows registry is very similar to the structure of the Windows file system. The keys are similar to folders and the values there stores are similar to files. Keys are referenced with a syntax similar to Windows' path names, using backslashes to indicate levels of hierarchy E.g. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\
The registry is structures in 5 logic categories or hives that begin with the prefix HKEY:
HKEY_CLASSES_ROOT
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
HKEY_USERS
HKEY_CURRENT_CONFIG
By simplicity, they are often designated by their abbreviations HKCR, HKCU, HKLM, HKU, HKCC respectively.
HKEY_CLASSES_ROOT
Stores a large amount of information that is critical to the functioning of Windows as, the file association, registered applications and OLE Objects Class IDs. Is important to say that it is a sensitive area and any error or data mistake can lead to the system malfunction.
HKEY_CURRENT_USER
Contains the profile of the currently logged-in user. The profile includes environment variables, desktop configuration, personal groups of programs, printers, network connections and application preferences and other personal preferences and security rights. The data in the user profile is similar to the data stored in the Win.ini file in Windows 3. x.
HKEY_LOCAL_MACHINE
The HKEY_LOCAL_MACHINE hive contains information about the computer that is running Windows. This information includes applications, drivers, and hardware. It also contains the Windows local security database There are five separate keys contained within HKEY_LOCAL_MACHINE: HARDWARE, SAM, SECURITY, SOFTWARE and SYSTEM.
HKEY_USERS
The HKEY_USERS hive contains information about each active user who has a user profile. In Windows. Two subkeys in HKEY_USERS key are .DEFAULT and the information for the currently logged-on user. The purpose of the .DEFAULT key is to provide information for users who log on without a profile. Information for the current user is stored under the user's SID (SID Security Identifier).
HKEY_CURRENT_CONFIG
The HKEY_CURRENT_CONFIG hive contains information about the system's current configuration. This information is gathered at runtime and is not permanently stored on disk, but rather regenerated at the boot time. The information is typically derived from HKEY_LOCAL_MACHINE\System and HKEY_LOCAL_ MACHINE\Software, though HKEY_CURRENT_CONFIG does not contain all the information that is contained in the source keys.
The registry has always been the one part of Windows operating system that virtually every user neither understands nor trusts. Preventing disaster and data loss are important things to do. Nobody wants a system failure or to have to reinstall Windows.
