When I turned Android Studio on Windows, I got this warning:
The use of Java options environment variables detected. Such variables override IDE configuration files (*.vmoptions) and may cause performance and stability issues. Please consider deleting these variables: JAVA_TOOL_OPTIONS.
So, I want to delete this variable, but I don't know how. This similar query didn't help me because I don't see this variable in system variables at all. I suspect I must have set it via the command line when I was troubleshooting another issue. Can it be deleted somehow?
