Microsoft's full release notes are online, but they've got and muddied the water by including info on Surface Book and Surface Studio (both nice bits of kit, if MS want to lend me a couple) but they have mentioned a few of the highlights in Creators Edition. Oddly though, (and in their words it will be "because there are so many awesome updates") they've missed out, or glossed over some of the changes which will matter most in the real world.
Without further ado, the changes I think we need care about are:
VASTLY improved scaled application redering - this is especially important for those pesky apps like Adobe Photoshop, which until now have been fairly un-useable on a high res laptop display Improved OOBE experience, particularly centred around metered or walled-garden style wireless connections. It might not sound like much, but I bet a whole raft of people benefit from this without even realising Loads of Windows Ink improvements; again they sound small, but when you use Ink a lot (or even a little) they make a huge difference Gaming Mode - this is massive for Microsoft; it's a whole bunch of updates and technologies to tie Windows 10 and X-box even more tightly together. You can now "cast" or broadcast / video share a game as you're playing it, and you can interact with people watching your cast in real time. MS are really wooing game developers with this release, and these features show that off in spaded Edge: Yep, as far as Microsoft are concerned, Edge is *the* browser that we should all be using. In the release notes (linked above) they make repeated and multi-asterixed claims about how Edge is now better than Chrome* (they don't pick a fight with Firefox... interesting...) and how it reneders more quickly, detects more phishing sites and upholds your battery better. I have to say that other than a few glaring omissions, I can actually now use Edge as my main browser, and I only swear at it occassionaly! ... there are loads and loads of other little things, like being able to have folders in the start menu. No, not the Applications list, like we've been able to do since Windows 95, this time we're talking about the tiled bit. Personally I don't know why you'd ever want to do this, especially not on a desktop, but I guess it makes sense in Tablet and Phone modes.
Here's a fuller list of changes I stole from another site (thanks ElReg)
