How to Block Chrome: Stop It From Opening

If Chrome keeps opening on its own, or you want to stop it from launching at startup, this guide shows you how to block it on Windows and macOS. You’ll learn how to disable background apps, remove startup entries, and set a different default browser, so Chrome stays closed until you actually open it.

What You’ll Need

• Access to your computer’s Settings or System Preferences
• Administrator rights (if Chrome was installed for all users)
• About 10 minutes of your time

Step-by-Step

On Windows

1. Close Chrome completely. Click the X on the window, but also check the system tray (bottom-right corner, near the clock) for a Chrome icon. If you see one, right-click it and select Exit. This ensures Chrome isn’t running in the background.
2. Disable Chrome’s background apps. Open Chrome, click the three-dot menu (top-right), select Settings, then System. Turn off the toggle for Continue running background apps when Google Chrome is closed. This stops Chrome from running processes in the background.
3. Prevent Chrome from launching at startup. Press Ctrl + Shift + Esc to open Task Manager. Go to the Startup tab, find Google Chrome in the list, select it, and click Disable (or right-click and choose Disable). This stops Chrome from starting when you log in.
4. Remove Chrome from the startup folder (if present). Press Win + R, type shell:startup, and press Enter. If you see a Chrome shortcut there, delete it. Also check shell:common startup for all users.
5. Set a different default browser. Open Windows Settings (Win + I), go to Apps > Default apps. Find Chrome in the list, click it, and choose another browser (like Edge or Firefox). This stops Chrome from opening when you click links.
6. Block Chrome from opening specific file types. In the same Default apps screen, scroll down to see file types like .html, .htm, and URL links. Click each one and select another browser. This prevents Chrome from opening when you double-click a saved webpage.

On macOS

1. Quit Chrome completely. Press Cmd + Q while Chrome is in focus. Check the Dock for a dot under Chrome’s icon, which indicates it’s still running. Right-click the icon and choose Quit if needed.
2. Disable background apps. Open Chrome, click Chrome in the menu bar, select Settings, then System. Turn off Continue running background apps.
3. Remove Chrome from login items. Open System Settings (or System Preferences on older macOS), go to General > Login Items (or Users & Groups > your user > Login Items). Find Chrome in the list, select it, and click the minus (-) button.
4. Set a different default browser. In System Settings, go to General > Default web browser. Choose another browser from the dropdown menu.
5. Block Chrome from opening automatically after updates. If Chrome updates itself and starts opening again, you may need to check its settings. In Chrome, go to Settings > About Chrome, and ensure automatic updates are on (you cannot disable them easily, but you can set your default browser again after an update).

Block Chrome on Mobile (Android/iOS)

1. Disable Chrome as the default browser. On Android, go to Settings > Apps > Default apps > Browser app, and select another browser. On iOS, go to Settings > Chrome > Default Browser App and choose another.
2. Disable background data (Android). Go to Settings > Apps > Chrome > Data usage, and turn off Background data. This prevents Chrome from refreshing in the background.
3. Restrict background activity (iOS). Go to Settings > Chrome > Background App Refresh and turn it off.

Common Mistakes

• Only closing the window. Closing the window doesn’t quit Chrome; it often keeps running in the background. Always use the exit option from the system tray or menu bar.
• Forgetting about startup items. Even if you disable background apps, Chrome may still launch at login. Check the Task Manager or Login Items as described.
• Not changing the default browser. If Chrome is still the default, clicking links in emails or documents will open it. Changing the default is essential.
• Assuming one setting is enough. Chrome has multiple ways to launch itself. You need to disable background apps, startup items, and change the default browser.

Tips

• Use a dedicated blocker. If Chrome keeps reopening due to a virus or malware, run a full antivirus scan. Some malware forces Chrome to open with ads.
• Check for extensions. Sometimes a Chrome extension can cause it to open on its own. In Chrome, go to More tools > Extensions, and disable suspicious ones.
• Clear your browsing data. If Chrome is slow or crashes, clearing cache and cookies can help, but this doesn’t affect whether it opens automatically.
• Consider uninstalling. If you never use Chrome, uninstall it completely. On Windows, go to Settings > Apps > Apps & features, find Chrome, and uninstall. On macOS, drag the Chrome app from Applications to Trash.
• Use a different browser as your main one. Once you set another browser as default, you’ll stop seeing Chrome pop up for links.

Troubleshooting

Chrome still opens after following all steps. First, check if there are multiple Chrome processes running. Open Task Manager (Windows) or Activity Monitor (macOS) and end all Chrome processes. Then re-check the startup items and default browser settings. If it persists, run a malware scan.

Chrome keeps opening a specific page (like a search engine). This is often caused by a hijacker or a malicious extension. Go to Chrome’s Settings > Search engine and reset it. Also check On startup settings and remove any unwanted pages.

You can’t disable Chrome because it’s greyed out. This can happen if Chrome is the only browser installed. Install another browser (like Firefox or Edge) first, then you can change the default.

Chrome re-enables itself after a Windows update. Windows may reset some defaults. Re-check the default apps settings after a major update.

Chrome opens when you click a link in an app. The app may have its own browser settings. Check the app’s preferences and set its default browser to something other than Chrome.
