What an operating system is and why it matters
An operating system is the main software that runs everything on your computer - Windows, macOS, or Linux. It manages your hardware and runs your other apps. Keeping it updated is one of the most important security things you can do.
An OS sits between your hardware and your apps. Without it, you have an expensive box with no way to use it. Windows and macOS are the main ones. Updates add security patches, so never skip them.

Common mistakes to avoid
- Assuming Windows 10 will continue to be safe after October 2025 -- it will not receive security patches and becomes increasingly vulnerable
- Confusing a Windows version number with a PC brand -- Windows runs on PCs from many manufacturers (Dell, HP, Lenovo, Asus, etc.)
Signs you need professional help
- PC does not meet Windows 11 requirements and a decision about upgrading hardware vs continuing with Windows 10 is needed
- Business computers need extended Windows 10 support past October 2025
