You have probably heard about Windows Registry. Someone might have already suggested you modify some registry entries to troubleshoot one of a Windows 10 problem. But, How much do you know about it? Do you know how to use it? Well, This article going to explain everything straightforwardly including how to take backup of Windows registry and restore it. You will know even more things.

What is Windows Registry?

The Windows registry is a database of Windows. It contains information, settings, options, and other values for programs and hardware installed on your PC. Most applications and software rely on Windows Registry. When a user installs any program on the Microsoft Windows operating system, it creates a new key/entry registry which contains the information about how the program will start and behave in your PC.

Different Types of Registry Values:

Windows registry consists of following things.


A registry key is something like a folder which contains registry values like String value, Multi-string value, DWORD, QWORD, Binary value, Expandable string value etc. It also may contain sub-keys like a folder contains sub-folders.

String Value:

It is one of the most used values in the registry. All string values are indicated by a small red icon with the letter ‘ab’. Often, You may need to modify some of the entries string values to solve or modify any functionalities on Windows. String values have some other types.

Multi-String Value:

It is similar to the string value. But, It contains more than one values unlike string value.

Expandable String Value:

This type of string value contains ‘%’ this sign. Windows uses an expandable string value for various purposes.

Binary Value

This type of entries contains binary values.

DWORD (32-bit) and QWORD (64-bit):

Both DWORD and QWORD values are expressed in decimal and hexadecimal format. WORD means 16 bit. DWORD means double WORD which means 32 bit. QWORD means Quad WORD which means 64 bit.
