How to make your web browser open on startup
This tutorial will show you step by step how to make Google Chrome, Microsoft Edge, Firefox, Brave, or another web browser open on startup on Windows 10 and 11.
We're going to make the web browser automatically open when Windows 10 or 11 starts.
Steps
1. Click on the Windows start menu button.
2. Right-click on the web browser's name > Open file location or More > Open file location.
File Explorer will open.
3. Right-click on the web browser's shortcut and then click on Copy. Or in Windows 11, you click on the 
(copy) icon or click on Show more options > Copy.
4. Right-click on the Windows start menu button and then click on Run.
A “Run” window will open.
You can also press the Windows 
+ R keyboard keys at the same time to open a “Run” window.
5. Type shell:startup in the “Run” window.
6. Click on the OK button or press the Enter key on your keyboard.
This command will open the Startup folder.
You can find the Startup folder here:
C:\Users\UserName\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
7. Right-click in the Startup folder and then click on Paste to copy the web browser's shortcut into this folder. Or in Windows 11, you click on the
