In today’s digital age, computers have become an integral part of our lives. From personal use to business operations, we rely heavily on computer software to accomplish various tasks.

But have you ever wondered what the most used computer software is? Let’s take a closer look.

What is Computer Software?

Before we dive into the most used computer software, let’s define what computer software actually is. In simple terms, computer software refers to a set of instructions or programs that tell a computer what to do. There are two main types of software: system software and application software.

System software includes programs that help manage and operate the computer hardware. This includes the operating system (OS), device drivers, and utility programs.

Application software refers to programs designed for specific tasks or applications. Examples include word processors, spreadsheets, email clients, web browsers, and multimedia players.

The Most Used Computer Software

According to recent studies and surveys, the most used computer software in the world is the Microsoft Windows operating system. As of 2021, it holds a market share of over 75% in desktop operating systems worldwide.

Windows was first introduced by Microsoft in 1985 and has since evolved into various versions such as Windows 95, Windows XP, Windows 7 and now Windows 10. It has become a household name due to its user-friendly interface and compatibility with numerous hardware devices.

Another widely-used application software worldwide is Microsoft Office Suite. This suite includes programs such as Word (for word processing), Excel (for spreadsheets), PowerPoint (for presentations), Outlook (for email), Access (for database management) and more.

Microsoft Office Suite has been around since 1989 and continues to be one of the most popular office suites in use today. It offers users powerful tools for creating professional documents, presentations and managing data while being compatible with multiple platforms such as Windows, Mac and mobile devices.
