[documentation] Which is the most feature complete WIndows build?

[eabase]

I really don't care about the gazillion different licenses and just want the most feature complete windows build.

From the README, you have the following variants for windows:

Available Variants

Variant Description
gpl Includes all dependencies, even those requiring full GPL.
lgpl Excludes GPL-only libraries (e.g., libx264, libx265).
nonfree Adds fdk-aac to all GPL dependencies.
gpl-shared Shared libraries (libav*) with GPL dependencies.
lgpl-shared Shared libraries with LGPL dependencies.
nonfree-shared Shared libraries with nonfree dependencies.

Which on of these has the most features?

[BtbN]

There is no "most featureful". Some stuff is gpl only, other stuff is lgpl only.
Technically, nonfree has it all, but it's not for download. If you want it, you'll need to build it yourself.

You'll probably be just fine with the gpl variant, unless you need something REALLY specific. lgpl notably lacks the x264/5 encoders, which are quite common to use.
