The Windows registry may be a small file, but it has a big job to do. Windows uses this database to store the information and settings related to installed hardware and software, as well as user preferences and other vital information. Whenever changes are made to the system, whether through the Control Panel applets, through software configuration or in some other way, the changes are recorded in the registry.
Because these files are so important, the Windows operating system does not allow users to make changes to registry files directly. Instead users must use a specially designed utility, known as the registry editor. This program can be invoked by clicking on the Start button, choosing Run from the menu and typing regedit in the box.
When the registry editor appears, the structure will resemble that of Windows Explorer, with a hierarchical layout, folders and subfolders. Users can drill down through these settings to find the entry, or registry key, they wish to change.
While manually editing the registry can sometimes be necessary, it can also be dangerous, and users are advised to always back up their registry before making even the smallest change. Backing up the registry allows users to restore the file to its previous state should something go wrong.
Since the registry is so critical to the proper operation of the Windows operating system, it is also a good idea to run a quality registry cleaner on a regular basis. Regular cleaning and optimizing of the Windows registry is one of the best ways to keep the system running its best and avoid problems down the road. Corrupted registry files and missing or extra registry keys can cause all sorts of issues, from unexpected system shutdowns and spontaneous reboots to sluggish performance. By keeping the registry in good repair PC owners can harness the power of this vital file and keep their computer running at top speed.
