U for Update

Prevent holes in your security. Don't give hackers a chance.

Old software is risky

Obsolete software often harbours security risks. It makes it easier for attackers to take control of a device. Software manufacturers therefore update their software regularly, and make the new version available to users. That’s why you should maintain your system, software and apps, and make sure to run the latest updates regularly.

Key points to remember:

Only ever install software and apps that you actually need, and make sure to download these exclusively from the manufacturer’s page or an official store.

Activate the automatic update feature not just for your operating system, but also for all the programs and apps you have installed.

Only ever use the latest version of your browser.

Updates improve security

“Right now, the biggest threat is ransomware. It encrypts the data on a computer, and makes the user a target for extortion.”

Updating software on your computer


Windows updates are activated as standard in Windows 10. This means that they are downloaded and installed automatically as soon as they become available.

You should also activate the
Receive updates for other Microsoft products when you update Windows‘ option.

To do this, go to Settings > Update & security > Windows Update > Advanced options. This means that other Microsoft products such as Office, etc. will be updated automatically.

You should no longer be working with Windows XP, Windows Vista and Office 2007 by now, as Microsoft no longer supports them.


Under macOS, system and software updates are provided centrally via the ‘Software Update’ function. The automatic software update function is activated as standard.

You should also activate these two options:

‘Install macOS Updates’

‘Install app updates from the App Store’

To do this, from the Apple menu, go to System Preferences > Software Update > Advanced.

Available updates are also always displayed under the App Store symbol in the dock. Clicking on them opens the ‘Software Update’ window, from where you can install the updates.


Updating software on your smartphone or tablet

Most smartphone operating systems will notify users when system updates are available. Check whether there is an automatic update function, and whether it has been activated, by going to ‘Software update’, ‘Mobile update’ or similar in your system settings. Installed apps can usually be updated via the Store. Depending on your operating system, all apps or those specifically selected can even be updated automatically. Always make sure that you update your operating system and all the apps you have installed as soon as possible.

OK with security updates?
