I'd guess around W95 also .. W98 at the latest. I wish they would update these older plugins. For example Parametric EQ; it is available as a hard write utility but not a realtime plugin. Seems they made all the others into realtime plugins but not the parametric EQ.

I complained once, long ago .. and have since found alternatives, but some features should really be updated so us old guys aren't the only ones knowing about them.

I do not work here, but the benefits are still awesome
