Ha-ha-ha! If you are using hardware from 2010 you are in bigger trouble anyway! Regardless what the bad guys say, here is the only one truth: Windows 10 (any edition) only works on SSD drives! Period! Why? Well, because it was designed that way. For example to supply water you have to use copper or plastic pipes. They designed for that. You cannot use paper pipes - they will melt in seconds. Same here: if you still use HDD - your Windows 10 won't work well. It will work, but much worse than XP or Win 7.
Besides, please try to understand one thing: ALL editions of Windows 10 are the same. Difference? Missing features. And different versions. But they are the same. And all applications works regardless. This is the worse thing that 99% of the people in this world truly believe that Apps needs to be re-tested! Ha-ha-ha! Those are time wasters and tire kickers! Those are truly bad guys! Because this way they can justify their salaries by doing nothing!
Although the concept of choosing LTSE for large enterprises just got better: Microsoft released new Edge browser that works on ANY Windows including Windows 7, 8, 8.1, and of course 10. Including LTSE. So now you are not limited to lousy and slow IE11. You can enjoy new EDGE which is absolutely best browser in the world today!
And the rest? Who use Cortana? Nobody. Who needs Store? Well, at home - YES, but for Enterprise this is a huge EVIL. This is a first thing that any Enterprise would ban and prohibit - MS Store. Because this is a big Pandora box. I hope you know why (you said you are security guy?). Hope this can help...
