How to setup a default program opening an unknown file extension?
However, I don't want the default program anymore...How do I restore it to my original way, where a window pops up and asks either I want to look on the internet to find a program or use one on my computer. I think its Microsoft commoner extension or something like that.

Right click on the unknown file and select Properties. Click on 'Opens with'. Choose the program you want to open it with.
