Windows registry is a registry database used for all of windows or non windows applications. The windows registry is a database which stores settings and options for Microsoft windows operating systems. It contains information and settings for all the hardware, operating system software, most non operating system software, and per user settings. The registry also provides a window into the operation of the kernel, exposing runtime information such as performance counters and currently active hardware. The infection usually occurs during a visit to a distributing web site using a web browser. A message appears in a dialog box or popup asking the user if they want to install Win Fixer, or claiming a users machine is infected with malware, and requests the user to run a free scan. Once installed, Win Fixer frequently launches pop ups and prompts the user to follow its directions. Because of the intricate way in which the program installs itself into the host computer (including making dozens of registry edits), successful removal may take a fairly long time if done manually. There is another special registry optimizer tool that reclaims system memory, accelerate startup time, free up disk space and boost overall system performance. Its tools include registry defragmenter, registry cleaners, disk cleaner, disk defragmenter, startup, service manager, restore center, system optimizer, process viewer, and performance test. As said by experts at MDofPC, a famous online store, registry backup utilities are going to be more popular in industrial and manufacturing IT companies. The registry stores the data in a structured hierarchy of keys, sub keys, and named values. Incorrectly editing the registry may severely damage your system. Microsoft recommends that you backup the registry before you edit it. Unfortunately, it is not possible to back up registry files under Windows NT, 2000, XP, and vista, while the operating system is running. Registry files remain fully locked all the time while Windows is running, so there is no access to those files. You can however use an integrated Windows XPs system restore feature for registry backup. There are lots of others registry backup application programs.
