On Windows 10, I successfully changed my java version to JDK 1.8:

```
C:\Users\Boommeister69>java -version
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.261-b12, mixed mode)

```

but javac doesn't change:

```
C:\Users\Boommeister69>javac -version
javac 11.0.7

```

when I `echo %PATH%` this is the result:

```
C:\Users\Boommeister69>echo %PATH%

So I have 3 paths showing up there with Java JDKs, the first JDK path is still set to Java 11. I think this is the problem, but I don't know how to change this? And why are there so many paths showing up, shouldn't `echo %PATH%` only return the system environment path variables?

These are my system environment path variables:

and my JAVA\_HOME variable:

I also changed the SDK in my IntelliJ, altough I don't think this has something to do with javac:
