How to make Chrome, Edge, Brave always open in full screen on Windows 10
This tutorial will show you step by step how to make Google Chrome, Microsoft Edge, or Brave always open in full screen or maximized on Windows 10.
Steps
1. Locate the shortcut you use to open your web browser. The shortcut can be in the taskbar, on your desktop, or in the Windows start menu.
2. Right-click on the web browser's shortcut and then click on Properties.
If you open your web browser from the taskbar, then right-click on its taskbar icon, right-click on the browser's name in the menu that appears, and then click on Properties.

Note: The menu with the “Properties” option may appear a little bit later after clicking.
If you open your web browser from the Windows start menu, then right-click on the browser's name > More > Open file location > right-click on its shortcut > Properties.

A “Properties” window appears.
3. Add --start-fullscreen to the end of the path in the Target field. Add a space between the path and --start-fullscreen (e.g., "C:\Program Files\Google\Chrome\Application\chrome.exe" --start-fullscreen).

Or if you want your web browser to always open maximized, then click on the selection menu button at Run and select Maximized.

4. Click on Apply button at the bottom of the “Properties” window.
5. Click on the OK button.
Your web browser will now always open in full screen or maximized.
If you use other shortcuts to open your web browser, then you will also need to edit them.
You can undo this change by editing the shortcut and removing the --start-fullscreen text you've added.
