This will probably be my only Windows and my only Java related blog post ever :(

The JDK version 11 is available from Oracle under a non-open-source license (which you probably don't want), and a GPLv2 license version, https://jdk.java.net/11/.

For Window, you get a .zip file, but no installer. The following has to be done manually:

1. Unzip to some directory, e.g. C:\jdk-11.0.1
2. Set PATH: Control Panel, System, Advanced, Environment Variables. Add C:\jdk-11.0.1\bin to PATH variable.
3. Set JAVA_HOME under System Variables. Create new variable JAVA_HOME, set value to C:\jdk-11.0.1 (without \bin)
4. Open RegEdit program. Create keys HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft, HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment. Create string value CurrentVersion and set it to the version to use, see below.

   Windows Registry Editor Version 5.00
   
   [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft]
   
   [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]
   "CurrentVersion"="11.0.1"
   
   [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\11.0.1]
   "JavaHome"="C:\jdk-11.0.1"
   

5. *facepalm*
