Running old WinXP and Win7 programs on Win10 and future CPU's.

Hello everyone.
This might be a silly question yet that's my level when it comes to OS.
I have one computer which is almost 10 years old and still running on WinXP. I've been keeping that old PC because I use a few programs that date from late 2000`s. They're all Win7 compatible too, but that's it, there were no further updates for the versions I have. One of them (ProTools 8 LE 3D Rendering Services) depends on external hardware whose driver is only compatible with XP and Win7. I've never planned to replace that PC for a newer one as it works perfectly, but I recently read something on future Intel and AMD processors about being Win10 only. Thus, I am not sure If I should buy a new PC now that Skylake's still are Win7 compatible and ensure using my programs for, let's say, 10 more years. I am worried about a possible breakdown of either my Core2 CPU or Motherboard in the next very few years (which would not certainly be a surprise coming from a computer set a decade ago) and not being able to use my programs any more, despite buying a new PC. As far as I know, modern versions of Windows feature the so called "compatibility mode" feature, which fools the software into thinking it’s running on the older Windows it requires. Also, there's the possibility of installing either a original XP or XPmode into a virtual machine, but will this solutions work for future CPU's that are supposed to be Win10 compatible only? Maybe it's a bit of stupid question, but it's messing with me...

Thank you all.
