I should mention this confusion in the blog. Also, note that even if there was a link to download JRE 1.6 or Java 8u160 for XP, it's not supported anymore. Advise the user to upgrade their OS if possible or use a virtual machine. Also, if they need to download an older version, direct them to the official archives. But if there's no official link, perhaps recommend open-source alternatives like OpenJDK versions that might still support XP, though that's uncertain.
