The answer in 30 seconds
Updates can fix security flaws and reliability problems. They can also require a restart or change how an app works, so it helps to keep a short inventory and plan the interruption.
Enable automatic updates where suitable, install security fixes promptly through the device or publisher's official channel, and review older devices whose support has ended.
Examples to adapt
Close it and check updates from the operating system or app's own settings.
Follow the organisation's managed update process and report a blocked update.
Check the vendor's support information and plan a safer replacement or restricted use.

What to check
A fake update notice can lead to malicious software.
