I can only speak about what I have tried and am not an i.t. guy to any depth . I have multiple P.C's running Win 7 and Win 10 , there was a time after spending countless hours of fiddling with them and tweaking settings that it all actually worked , not so anymore and i refuse to waste any more time on something that the next update could trash .
Microsoft may never get proper networking fixed , in fact it seems to have become worse instead of better .
So , since i pay for a VPN anyway's , starts with a "N" I have been using the inclusive file and folder sharing abilities that have been built in for at least 6 months now . No...not nearly as good as proper networking would and should work . Also requires that you have access to the P.C's that you are sharing folder's/files from . If one is at a another location or in a locked room then you must wait til you are seated at it to send or recieve . Otherwise...works fine .
