I rarely turn of my desktop computer but sometimes I need a restart. Of all the programs that open automatically on startup, I would like my email program, Thunderbird, to be one of them. Thunderbird, as of this writing does not have that support option. But you can use Windows Start to do that. Here's how.
Note: You can use this method to set any program up to start up automatically when you turn on or restart your system.
First, click on the start button and find Thunderbird (in my case) in the list of programs. Right-click on it and in the menu that opens click on “More” and then “Open file location”.
This opens to the list of icons in the start menu. Right-click on Thunderbird and click “Copy”.
Then on your keyboard click on the Windows Key + R. Or right-click on start and then Run. Or search for the Run box.
In the run box type the following and click OK:
shell:startup
This will open Windows Startup folder that may or may not contain any icons right now. Mine is empty. Everything that is in this folder will start up automatically when you first turn on your system or restart.
Right-click on the right-hand side of the window and click on “Paste”. That's it. So you can now test it by restarting your system.
The path: C:\Users\(your account)\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
