How to add a program to run at startup

The are a lot of programs around that let you delete, enable and disable a program from running at startup on your computer. That's all very convenient, but what if you have a program that doesn't start when you power up your computer and you do want it to start?

The procedure is relatively easy

[1] Start by hitting the 'Windows key + R', which opens the Run dialog.
[2] Then type 'shell:startup' or 'shell:common startup' in the Run dialog and hit Enter*
[3] The Startup folder opens and you can drag 'n' drop (or copy-paste) a shortcut of a program into that folder.
[4] Close the folder by pressing the 'x' in the top-right corner.

The next time you'll start your computer, this program will 'automagically' start too.

* You should choose 'shell:startup' if you log into your computer using your user account. You should choose 'shell:common startup' when you allow any user to log in.
