While I still love Windows 7, maybe a bit too much, because when my XPS 8700 arrived with Windows 8 in UEFI/GPT mode in September 2013, it was a costly decision three years back to revert to MBR to keep the OS. Now am playing catchup after three years missed w/out UEFI (self-built new PC just over a month back) could had installed Windows 7 using VM software or Hyper-V machine & kept on going, learning the new, while having the best of both worlds.
It would be fantastic if Windows 7 would support UEFI, kind of odd that Microsoft allowed Linux this feature with a $99 key, yet not their largest customer base, which still remains so today. While I've heard of workarounds, don't want to be running a non-genuine version of Windows 7, or violating the EULA, one part which refers to reverse engineering for one's use of the OS.
I have a strong hunch that Windows 7 will be the last greatest OS that Microsoft released, considering it's very popular reception (similar to XP) & still retention rate of today. While Windows 10 at some point will take over, it won't be due to popularity, rather by what the market has provided the last few years. And while one can still get Windows 7 Pro, the return on investment would be poor, considering W7 has just over 3 years of support left, in that regard, 8.1 Pro is a better option.
Though I suspect the holdouts for Windows 7 will be much larger than those for XP, and usershare will hold solid for 2-3 years afterwards.
BTW, my build, of which I'll install a Windows 7 VM on, or venture into the Hyper-V world. For whatever reason, the GTX 1070 FTW shows as 4GB VRAM. has been verified to have 8GB by GPU-Z, and anyone who knows these cards, knows there was no 4GB FTW version.

I'll run Windows 7 in some form until the wheels falls off!
