user1985273 :
Im a bit confused about how to download openjdk8 for windows.
If I go to http://openjdk.java.net/install/ then under JDK 8 there are only two sections: "Debian, Ubuntu, etc." and "Fedora, Oracle Linux, Red Hat Enterprise Linux, etc.". Where is windows?

Go to this link
Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download
Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.
