What is the Registry?

The Windows registry is a central hierarchical collection of software, hardware and user settings that are present in your machine. It is used in Microsoft Windows 9x, Windows CE, Windows NT, Windows 2000, Windows Millennium, Windows XP and Windows Vista. Although the Registry is common to several Windows operating systems, there are some differences among them. The registry plays a very important role in your computer’s operating system, for example, by allowing Windows to start and ensuring the stability of the entire system.

When the user makes any modifications to Control Panel settings, file associations, system policies and installed software, all these changes are reflected and stocked up in the registry. The Registry replaces most of the text-based .ini files used in Windows 3.x and MS-DOS configuration files, such as the Autoexec.bat and Config.sys.

Why is it important to remove malicious registry entries?

The majority of all hazardous parasites, especially Trojans, browser hijackers, spyware and adware threats have the ability to change the Windows registry. The malicious programs usually add various registry entries, generate new keys and modify default values. That’s why it is important to learn how to remove malicious registry entries so you can quickly detect and remove deep-seated infections. Invalid registry entries may cause a serious harm, and they may be a reason of sluggish performance of your PC as well.
