The Complete Guide to Computer Operating Systems

Why Operating Systems Matter

Every computer, from desktops to laptops, relies on an operating system (OS) to function. It’s the bridge between hardware and software, allowing you to run applications, connect to the internet, and manage files. At PC Revive, we often help customers with OS-related problems, from blue screen errors to full operating system reinstalls.

This guide breaks down the different types of operating systems, their strengths and weaknesses, and how our team can support you in maintaining or upgrading your system.

What is an Operating System?

An operating system is system software that manages computer hardware, software resources, and provides services for programs. Without it, a computer cannot function.

Popular examples include Microsoft Windows, macOS, and Linux distributions. Each has its own ecosystem, compatibility, and features.

When to Upgrade or Reinstall Your Operating System

Operating systems have lifecycles. Microsoft, Apple, and Linux distributions regularly end support for older versions. Running outdated systems can expose you to security risks and compatibility issues.

At PC Revive, we recommend:

  • Upgrading when support ends (e.g., Windows 10 support ends in 2025).
  • Reinstalling if your system is slow, corrupted, or heavily infected by malware.

Consider hardware upgrades like RAM or SSD replacements to pair with an OS update for the best results.
