Looking for a reverse compatibility matrix for Networker client software: (I mean: starting from the windows client version)

I have a number of different windows systems to backup and I need to find the correct/best (supported) Networker client version for each of them:

What I already know (found this by using the online compatibility matrix and selecting every Networker version in turn):

Windows 2003 client : maximum version : Networker client v8.1  (v8.1.3.9 ? )

Windows 2016 server : minimum version : Networker client v9.1

So what about Windows 2000 (I know :-) , don't ask) and windows 2008(r2) and 2012(R2) ?

Any advise ?
