Switching between JDKs in Windows

A practical guide to managing multiple JDK versions on Windows using PowerShell. After removing all non-IntelliJ-managed JDKs and clearing JAVA_HOME and PATH, the author sets a default JDK via user environment variables and creates a PowerShell script plus profile functions to switch between JDK versions per session. The approach leverages JDKs already installed by IntelliJ IDEA, avoiding third-party version managers like vfox.
