Sorry, but you really have to take into account that Microsoft have literally rubbed a lot of regulars here up the wrong way.
That and the fact that a large proportion of netbooks that still remain in service cannot take advantage of the W10 "free" upgrade package, either because they are running WXP or because they are running Linux.
Don't get me wrong - I've often tried getting older hardware to run newer systems. Probably the silliest attempt was testing W7 and Windows 2008 Server betas on an old PIII laptop... and yes, they worked! The thing is, however, that many of us that have posted about our netbooks running Linux have no real intention of loading in a replacement OS like this, whatever the outcome of such a trial is.
And since the netbook is dying out anyway, is there really a point? That PIII I mentioned was never used in that form for anything serious - it was just a curiosity. As soon as it was all over, it was scrapped. Bringing an old system back to life is a worthy cause and I've done it on so many occasions but I doubt that I would do it with W10 in its current state (let me clarify - "excellent" is not a phrase I'd couple with W10 right now), not because I couldn't, but because of all the reasons that have been pounded out here before on so many threads.
