How to stop apps from auto opening on startup from Windows 11?

Using the Registry Editor to stop apps from auto opening on startup in Windows 11 involves directly editing the system's registry keys that control which programs launch when your computer boots up. This method provides a powerful way to manage startup apps beyond the usual settings interface.

In simple terms, Windows stores information about startup programs in specific places called registry keys. By opening these keys, you can see which applications are set to run automatically. If you find any unwanted apps there, you can delete or disable their entries, preventing them from launching every time you start your PC.

Here's a basic overview of how it works:

1. Access the Registry Editor: You open a special tool called the Registry Editor, which allows you to view and modify these system settings.

2. Navigate to specific locations: You go to certain folders within the registry that list startup programs — mainly under HKEY_CURRENT_USER for programs specific to your user, and HKEY_LOCAL_MACHINE for programs that affect all users.

3. Identify unwanted startup entries: Inside these folders, you'll see entries with names and paths of applications that are set to run at startup.

4. Disable or remove entries: You can delete these entries or modify them to stop apps from auto opening on startup. Deleting removes the startup command, so the app won't launch automatically next time.

5. Restart your PC: After making these changes, reboot your computer to ensure the unwanted apps no longer start automatically.

This method is effective but should be done carefully. Making incorrect changes can cause issues with your system. Always back up the registry before editing, so you can restore it if something goes wrong.
