Why you should install software updates and operating system updates today

What is a software update?

A software update is a new version of an application, game, or other program on a computer or mobile device. New versions of software usually include patches to fix security vulnerabilities, performance upgrades, and cosmetic changes.

The importance of software updates

Keeping your software and operating system up to date is an important step toward ensuring your information is safe, your device is secured and working properly, and your programs and system remain compatible with each other. 

Here’s a closer look at the benefits of software updates and why you should always keep them fully updated.

A software update reduces security flaws

Old software is full of security flaws. Over time, hackers find new ways to break through what was, at one time, the best available protection. Once these cybercriminals break into a system, they can spy on your computer, implant dangerous malware, or even use what they find in your system to commit identity theft.

Software updates are there to patch zero-day exploits and update older, less effective protocols to the newer, tougher-to-crack standards. This makes updating all your software one of the most critical ways to improve your computer and mobile security.

A software update helps protect your data

Your data is at risk of being stolen, sold, and used against you by criminals. But the risk of being hit by a data breach is much higher if you’re using outdated software, as is the risk of accidentally destroying or corrupting your files.

Updating your software to the latest versions can close off any vulnerabilities that let hackers in. Updates can also correct problems that could corrupt your files while making sure they’re compatible with the newest versions of the programs you use. 

A software update improves performance

If you want to make your computer faster, one of the easiest ways is to update your software. Older software versions operate using legacy code and protocols, but engineers are constantly making tweaks to improve performance and reduce resource usage. With more RAM available, your devices can do more — and do it quicker.

Reliably high performance is vital for running multiple programs simultaneously, watching high-definition videos, playing the newest games, taking the best pictures and videos, and even browsing the internet. 

Software updates help protect others

The internet is a giant, interconnected network of devices. Because of the links between systems all over the globe, keeping your devices updated and free of malware and viruses that spread through networks is like covering your mouth when you cough in public.

Doing your part can reduce the headaches and economic impacts of cybercrime and malicious software in your neighbourhood as well as the farthest corners of the planet. And don’t think you’re less susceptible when using a Mac — Macs can get viruses, too.

How to keep software and operating systems updated

For most modern devices, it’s easy to keep your apps or OS updated. Let’s look at two of the best ways to stay as up to date as possible:

• Look for notifications: The Apple App Store, the Google Play Store, Android and iOS devices, and Windows and Mac OS computers will tell you when an update is ready for installation. You might receive a push notification, see a flag or bubble on the store or settings icon, or may need to go into the update menu directly.
• Turn on automatic updates: Almost every device will let you turn on automatic updates for apps and operating systems. This process can vary depending on your device, but a good place to look for these settings is in the device settings section or store settings. 

Keep your devices safer and up to date

Apps and operating systems are one thing, but manually updating your drivers so that your software and hardware keep working together smoothly isn’t always easy.

Norton Driver Updater will help scan your Windows PC for outdated drivers automatically, suggest the newest and most compatible drivers for your system, and screen the drivers for malware before you install them. Get updated, stay updated, and unlock enhanced security and better performance. 

FAQs about software updates

What happens if I don’t update my software?

If you don’t update your software, you’re at greater risk of system problems, hackers, malware, and compatibility issues. Older versions are usually less efficient, meaning your computer runs slower and may struggle to multitask or handle RAM-heavy tasks like audio or video editing.

Are there any risks to software updates?

There are some risks to updating software and operating systems. Any new version of an app or OS is almost certain to contain some security vulnerabilities. And if you have an older device, newer software might malfunction due to new hardware requirements. Even with those potential risks, the security and performance benefits of updated software far outweigh the downsides.

How do I know if my software is up to date?

The easiest way to check if your software is up to date is to see if updates are available wherever you normally update your software. This usually means checking for Apple App Store or Google Play store updates. You can also usually find any available updates via your system settings.

What is the risk of running outdated software?

If you run outdated software, the known vulnerabilities in older versions of apps and operating systems mean you’re at a higher risk of being hacked. Additionally, your phone could run hotter, your device might fall prey to malware, and your computer may not run as smoothly as it could.
