The system registry, or the Windows registry, is a database for storing the operating system settings, installed programs, user and equipment parameters, in addition, the registry stores information about the configuration of computer devices. The Windows registry is a kind of collection of system settings, applications, tools, and various services. As a rule, far from everything is available for the settings accessible to users through the interface of the Windows operating system. Some subtle settings are hidden from the eyes of users, and only more advanced users or even professionals can use them, just using the registry.
The registry’s automatic change occurs if the program is set to update the current state of values automatically. It also does not require confirmation to alter the original settings if the latter was saved as the default one. In addition, the registry undergoes an automatic change during the major updates, where the key properties are modified. The given instrument can also change without request if it was specifically allowed to do so. The registry additionally changes if the operating system possesses a certain malware that affects its process regulation.
