Got the answer from ChatGPT:

To add software to auto-start in Windows 10 when booting, you can place the application’s shortcut in the Startup folder. Press Win + R, type shell:startup, and press Enter to open the Startup folder. Then, create or copy a shortcut of the software you want to auto-start into this folder. Upon the next reboot, Windows will automatically launch the applications present in the Startup folder.

If Win + R is not available, you can do the following.

1. Open Task Manager.
2. Click on “File” in the top menu.
3. Select “Run new task” from the dropdown menu.
4. Type shell:startup and press Enter or click “OK.”
