Windows registry is a database that stores settings and options for Microsoft Windows 32-bit version of Windows Mobile and the 64-bit version of the operating system.
The information it contains and all hardware, software, users, and preferences of the PC. Whenever a user on "Control Panel" settings, or file associations, system policies changes are made or installed software, the changes are reflected and stored in the registry.
Registry, you are setting a large file can store a large number of locations.
This document has been around for quite some time, and have different names. Use the Windows registry to store settings the first Windows version Windows 3.11, Windows registry in this version is called the Reg.dat.
In Windows 95 and 98, the registry files are named User.dat and System.dat and is stored in \Windows\ directory.
Windows ME registry file, the Classes.dat, User.dat, System.dat and is stored in \Windows\ directory. Finally, like the latest version of windows,Windows NT, 2000, 2003, stored with the XP registry file like this,
Files are stored in the registry in%SystemRoot%\system32\config\:
• Sam
• Security
• Software
• System
• Default
Userdiff •
NTUSER.dat •
• The NTUSER.dat file is stored in the profile folder.
Describes how Windows registry archive old text stored in the INI file. Furthermore, these entries and store the configuration settings for Windows.
List of Ini file is stored in many different locations and many programs use their own ini files of some or all of the settings. Use the ini file system in this way, making them difficult to track and deal with a simple logic in methods.
What is a good registry
From each show one or multiple INI files to a centralized registry change has some obvious and some not-so-obvious benefits:
• Break the machine configuration user configuration in the registry. When a user logs on to Windows NT/XP/2003 year's computer, its registry settings system-wide settings and merge. This makes the program easier to maintain per-user configuration, because they can only use the current user key, and in the past, they often just to keep the system-wide settings. Although there is a common system-wide settings for all users.
• Group Policy allows administrators to centrally manage program and policy settings on a Windows-based computer networks. Not in the family environment, in company with a dedicated log server only.
• Through a special API is available to access the registry script and remote management using WMI. Each scripts do not have to give each application a unique profile layouts and limited customization.
• Registry remote management/support, including from scripts, network connection using a standard API to access as a project.
• It can be backed up more easily, it is only a small number of a specific position in the file.
Bad things, and the registry
Not all that glitters is not gold. Registry introduces some problems:
• It is a single point of failure-damage to the registry can render a Windows system fails to boot, in the extreme point is not fixed and you need to completely reinstall Windows. This is why it is so important, using the registry scan and repair utility, repair the registry at the same time.
• You want to manipulate the registry you must use any special Windows API function and configuration files can be used plain text file processing operation.
• Configuration files can contain comments and Notes users to explain what and how to change the value, the registry could not be. Something called a GUID in the registry is large in scale. Long strange is totally meaningless, unique number to humanity. More difficult to deal with.
• It is more difficult to backup-not ' alive ', because it is always in use, and therefore require special software (such as Ntbackup).
• Restore the registry part is difficult, because you can't easily extract the data from the backup registry files
• Incorrect, remove or remove programs, there is no application in the registry, and can increase the file size over time result in degraded performance from entry. Again, here, you have to use Registry scanning/cleaning and repairing the main reason software.
The registry will publish the new Vista operating system from Microsoft again heavy.
