how to delete java completely from windows-CodePudding

I have messed up my windows java installation and i want to delete everything and re-install java , all of my java versions have been messed up and I don't know what to do in this situation when I do:

C:\Users\LENOVO>echo %JAVA_HOME%
C:\Program Files\Java\jdk-17.0.1

C:\Users\LENOVO>javac -version
javac 17.0.1

C:\Users\LENOVO>java -version
java version "1.8.0_311"
Java(TM) SE Runtime Environment (build 1.8.0_311-b11)
Java HotSpot(TM) Client VM (build 25.311-b11, mixed mode, sharing)

Why is java -version showing different things?

I HAVE TRIED CHANGING PATH AND THERE IS NOTHING IN MY PATH RELATED TO JAVA 1.8.0.

I TRIED MANUALLY DELETING JAVA BUT IT ALWAYS SAID IT IS OPEN SOMEWHERE ELSE AND CLOSE THAT BEFORE MAKING ANY CHANGES HERE

CodePudding user response：

first of all you must go environment variables and then delete all Java related paths and after that follow those links and delete them also from your local computer. It's done :)

CodePudding user response：

I'm not sure how to fix the issue regarding it being open elsewhere but I'd recommend trying to open task manager to close Java that way.

As for uninstalling it, you can uninstall it as it is an app. Just open settings, go to apps, search Java, and uninstall it like so.
