It is important that you maintain your computer on a regular basis to make sure that errors are fixed and improvements are implemented. Software updates ensure that this happens.
Update your software
When you update your software, you close the security holes in software that hackers, malware and viruses find and exploit to access your PC. Update all your software – operating system, browser and all other programs – on a regular basis.
If you choose automatic installation of security updates, you don’t have to worry about forgetting an update.
Windows operating systems can be updated using Windows Update. Mac OS X can be updated with Software Update.
