Getting the most out of a computer means managing (installing, updating and uninstalling) the applications you want to have available.
Most systems focus on using their “Store”
- Google Play Store
- App Store (Apple)
- Windows Store
But apps can also be downloaded and installed from other trusted sources

All software needs to be updated from time to time, at very least to:
- maintain compatibility with new computers
- resolve security issues
- fix bugs
