What is Windows Registry & How to Create, Modify, Backup and Restore Registry Entries

You’ve probably heard of the Windows registry. Someone may have suggested that you need to change some of the registry entries to diagnose one of the problems with Windows 10. But what do you know about it? Do you know how to use it? In this article we explain everything easily, including backing up and restoring the Windows registry. You’ll find out more about this.

What is the Windows registry?

The Windows registry is a Windows database. It contains information, settings, options and other values for the programs and devices installed on your PC. Most applications and software are based on the Windows registry. When a user installs a program on a Microsoft Windows operating system, he creates a new key/login that contains information about the operation and behavior of the program on your PC.

Different types of registry values:

The Windows registry consists of the following parts.


A registry key is a file type that contains registry values such as B. String value, multi-string value, DWORD, QWORD, binary value, expandable string value, etc. It can also contain subfolders, for example a folder contains subfolders.

Chain value:

This is one of the most commonly used values in the register. All line values are marked by a small red icon with the letter ab. It may often be necessary to change some of the values in the record lines to resolve or change the Windows functionality. Ironing values have other types.
