Automatically fix _JAVA_OPTIONS issues
_JAVA_OPTIONS is an environment variable which in alot of cases overwrites your maximum ram setting from the launcher, generally to only half a GB. Removing this environment variable is necessary in order for ATLauncher, Minecraft and other Java applications to use more than that set ram.
To fix this simply download this script and run it as administrator (Right click it and select "Run as administrator"). This will auto remove the _JAVA_OPTIONS environment variables for you.
Alternatively you can delete them manually through the 'Edit Environment Variables' setting (sometimes called 'Edit Environment Variables For This Account') and delete the _JAVA_OPTIONS setting and restart ATLauncher. A more detailed video is available below to guide you through how to remove it.
