The fastest way depends on your operating system and how you installed the app

Most applications on Windows update through a menu inside the program itself. Open the app, look for a menu labeled "Help," "Settings," or the three horizontal lines (called a hamburger menu), then find "Check for Updates" or "About." The app will read and install the new version, sometimes asking you to restart. On Mac, many apps update through the App Store app on your dock, or through the same Help menu route. Linux users typically update through their system's package manager — Ubuntu uses Software Updater, Fedora uses GNOME Software — which handles all installed programs at once rather than one at a time.

The method matters because it affects how often you see updates and how automatic they can be. Apps installed from the Microsoft Store or Mac App Store can turn on automatic updates in their settings, so you never have to think about it. Apps you downloaded directly from a website usually require you to check manually, though some (like Firefox, Chrome, and Zoom) check for updates every time they start.

Key Takeaways

  • Windows apps installed from the Microsoft Store can turn on automatic updates in Settings, while apps downloaded directly usually need manual checking through their Help menu.
  • Mac users can enable automatic updates for App Store apps in System Settings, but apps downloaded from websites typically update through their own Help or Settings menu.
  • Linux systems update all installed programs at once through the package manager (Software Updater on Ubuntu, GNOME Software on Fedora), not through individual apps.
  • Restarting your computer after an update ensures the new version fully takes effect, especially for system-level applications.
  • Turning on automatic updates for critical apps like your web browser and antivirus software reduces the window of time your system is vulnerable to known security problems.

Updating apps on Windows

Windows has three separate update paths depending on where you got the app. If you installed it from the Microsoft Store, open the Store app, click your profile icon in the top right, select "App settings," and toggle "Update apps automatically" on. You can also manually check by clicking "Library" and then the update icon next to any app that has a pending update.

If you downloaded the app directly from a website (like downloading Firefox from mozilla.org or Slack from slack.com), open the app and look in the Help menu. Most mainstream programs have "Check for Updates" or "About" somewhere in that menu. Click it, and the app will either tell you that you are on the latest version or read the update automatically. Some apps, like Chrome and Firefox, check for updates every time they launch, so you may see a notification that an update is ready the next time you open them.

After an update finishes, the app usually asks you to restart it. Close the program completely and open it again. If the update touched system files (less common for individual apps), Windows may ask you to restart your computer — do this as soon as you can, because the update does not fully take effect until you do.

Updating apps on Mac

Mac splits updates between the App Store and apps you downloaded directly. For App Store apps, open System Settings (the gear icon), click "General," then "Software Update." Under "Available Updates," you will see both macOS updates and app updates. Click "Update Now" next to any app, or toggle "Automatic Updates" on to have them install overnight. You can also open the App Store app from your dock, click your profile icon in the top right, and see pending updates there.

For apps you downloaded directly (like Microsoft Office, Adobe Creative Suite, or Zoom), open the app and look in the menu bar at the top of your screen. Click the app's name (for example, "Firefox" or "Zoom"), then look for "Check for Updates" or "About." The app will read and install the update, usually without closing itself. Some apps, like Chrome, check automatically every time they launch.

After updating, you may see a notification asking you to restart the app or your Mac. Restart the app when ready by closing it completely and opening it again. If macOS itself updated, restart your Mac when prompted — updates to the operating system do not take effect until you do.

Updating apps on Linux

Linux handles updates differently because most apps come from a central repository managed by your distribution. On Ubuntu, click "Activities" in the top left, search for "Software Updater," and open it. The tool will scan your system, show you all available updates for every installed program, and let you click "Install Now" to update everything at once. You can also open "Software" (the app store), click your profile icon, and toggle "Automatic Updates" to have updates install in the background.

On Fedora, open "Software" from your applications menu, click your profile icon, and turn on "Automatic Updates." To manually check, open the same Software app and look for a refresh icon or "Check for Updates" button. Some apps, like Firefox, also have their own update mechanism and may check for updates independently of the system updater.

After updates finish, you may see a notification asking you to restart your computer. Do this as soon as practical, because system-level updates do not take effect until you reboot. Individual app updates usually take effect when ready without restarting.

Turning on automatic updates for the apps that matter most

Not every app needs to update automatically, but a few should. Your web browser (Chrome, Firefox, Safari, or Edge) should always update automatically because browsers are the main entry point for malware and hackers. Your antivirus or security software should also update automatically, because it needs the latest threat definitions to protect you. Operating system updates (Windows, macOS, or Linux) should update automatically for the same reason.

Less critical apps like note-taking programs, media players, or games can update manually on a schedule you choose. Turning on automatic updates for everything can cause unexpected restarts or slow your computer during updates, so balance security with convenience. A good middle ground is to enable automatic updates for security-related software and your browser, then manually check other apps once a month.

What to do if an update fails or causes problems

If an update starts but does not finish, restart your computer and try updating again. Most apps will resume the update or start fresh. If the same update fails twice, try uninstalling the app completely and reinstalling it from the Microsoft Store (Windows), App Store (Mac), or Software app (Linux). This gives you a clean installation of the latest version.

If an app stops working after an update, restart your computer first — this solves most post-update problems. If the problem persists, check the app's website or support page to see if other users reported the same issue. Some updates have bugs that the developer fixes quickly with a follow-up update, so checking for another update may solve it. As a last resort, you can uninstall the app and reinstall the previous version from the app store, though this is rarely necessary.

Frequently Asked Questions

Do I have to restart my computer after every app update?

No. Most individual app updates take effect when ready without restarting. You only need to restart the app itself by closing it completely and opening it again. Restart your computer only when the update specifically asks you to, which usually happens with system updates or updates to core system files.

Can I turn off automatic updates if they are slowing down my computer?

Yes, but do this selectively. Turn off automatic updates for non-critical apps, but keep them on for your browser, antivirus software, and operating system. You can also schedule updates to run at a specific time (like 2 AM) so they do not interrupt your work. Check your app's settings or your system settings for scheduling options.

What if I do not want the latest version of an app?

You can delay updates by turning off automatic updates and checking manually on your own schedule. However, do not skip security updates for your browser or antivirus software — these fix vulnerabilities that hackers actively exploit. For other apps, waiting a week or two after a new version releases is reasonable if you want to avoid early bugs.

How do I know if an app is actually updated?

Open the app and look in the Help or About menu — it usually shows the version number. Compare this to the latest version listed on the app's website or in the app store. If the numbers match, you are on the latest version. If the app has a "Check for Updates" button and it says "You are up to date," you have the latest version.

Do I need to update apps if I do not use them often?

Yes, especially for security-related apps and your browser. Outdated software has known security holes that hackers use to break in, even if you do not use the app every day. Set a reminder to check for updates once a month for apps you use occasionally, or turn on automatic updates and let them run in the background.
