Have it running on my VMware environment.
Essentially, it's Windows trying to be Android. Their app store looks exactly like Google Play. The start menu is back, but goofy. It's half normal, half metro. But if you unpin all of Metro thingies, it disappears and it's almost ok. Classic Shell isn't an absolute mandatory necessity like it is with Windows 8 and Server 2012, but it would still be a significant improvement over stock Win 10 start menu.
As a tip, try right clicking on start menu.
Overall, it's functional. It's what Windows 8.1 should be (it's really just Win 8.2), but Windows 7 is much better for most users. With absolutely no sarcasm or joking, Win 10 is much better than XP, 7, 8.1 for folks that are technology illiterate. However, if you have even minimal experience with using technology, Win 7 is better.
