Great.
You will need Java installed, so if you have removed that then you should re-install Java, we recommend Java 17.
Then go to Windows Setting / Apps / Installed apps.
There you should see "Zed Attack Proxy by Checkmarx 2.17.0" - you can search for "ZAP" if you have lots of programs.
Clicking on the "..." (More options) should give you a menu with "Modify" (which will be greyed out) and "Uninstall".
Yep, you should select "Uninstall".
At least thats what I see on a Windows box I had to hand.
If you have a different version of Windows installed then you may see something different.
But as I understand it, we are following the recommended best practices for uninstalling applications.
Cheers,
