Hello,

Unfortunately you do not say which type of software or even on which hardware.

macOS?

Apps on a Mac?

iOS?

iPadOS?

Apps on an iOS or iPad OS device?

Here's a few ways depending upon which hardware and software.

Update your iPhone, iPad, or iPod touch. Click here --> Update your iPhone or iPad - Apple Support

Update macOS on Mac - Apple Support

For apps on a mobile device --> App Store app > Updates, or select your icon in the upper right corner > click update all or scroll down past the first screen to select individual apps.
