I am not able to program my second arduino because they both use the same com port. In other words this picture says it all:

In order to upload my sketch I have to disconnect one arduino. How can I tell windows to use a different COM port?

It will be nice if I do not have to disconnect one arduino evey time I want to upload a sketch. I already restarted my computer and I get the same problem.

I did not knew I could change the port on windows. This is how I did it thanks to @Majenko's comment.
