[Oberon] Where's V4 for Win10 ?

The wave of in-yo-face-garbage from eg. Win10, has become intolerable, V4 under Win8.1 was usefull. Remind me: can Win:V4 <cd to any Dir which Win can access> and read/write from there, without specifying the full-path? And perhaps even have another instance <cd-ed to a different dir>? Where to D/L & install it for Win10? ==TIA.
