Auto-naming of trackpoints

[Zadig]

There are a hidden options to avoid writing aspects of GPX waypoints:

[HKEY_CURRENT_USER\Software\JavaSoft\Prefs\slash\navigation\gpx]
"write/Accuracy"="true"
"write/Elevation"="true"
"write/Extensions"="true"
"write/Heading"="true"
"write/Meta/Data"="true"
"write/Name"="true"
"write/Speed"="true"
"write/Temperature"="true"
"write/Time"="true"
"write/Trip"="false"

Hi Christian and thank you for your help. Does it mean that I can play with these preferences and change "true" by "false" in some of them ? And how ? Your answer seems to be for Windows users and I don't know what file I have to open in MacOS : plist ?
