Agreed I will still have 7 for a while longer, windows 7 professional 64-bit works wonders for me and I have a gaming PC so I do not see a need to change it for the next couple of years maybe and I do not see win 10 hitting a very large scale enterprise environment that I work in for at least a around half a decade to a decade, and that’s a huge maybe, I will still play with it though.

WIn-7 Pro here also. If Win-10 improves performance over the 7-Pro I might be interested.
The interface change would be a least of my concerns as long as the customizing ability is there.

I skipped 8.1, never even messed with it, no reason to.
