Keep Your Operating System Up To Date

Operating systems, like Windows and MacOS (formerly Mac OS X), are made up of countless parts with different functions ideally working in harmony. That some of these parts should be less than perfect is inevitable. But when a problem leaves a hole in your machine's defenses, it is extremely important to patch it as soon as possible. This is best accomplished by using built-in automatic update features through the Windows Update Page in the Windows Control Panel for Windows PCs, and the Software Update feature,  on MacOS and OS X systems. Keep in mind that your machine may need to be restarted after you update.
