To trace them under Windows, start Process Monitor
add the following filters:
* "Process Name", "is", "Start Tor Browser.exe", include
* "Process Name", "is", "tor.exe", include
* "Process Name", "is", "firefox.exe", include
* "Operation", "is not", "RegSetValue", exclude

Well, I'm not a big fan of access() checks in software due to races.
Plus, they tend to be somewhat complex in Windows - you have to fetch
a DACL and loop over ACLs looking for allow and deny ACEs. Its usually
