man, you slackers didn't make an "official info" 8.1 thread? Come on, don't make me do this myself
that "leak" thread is an incomplete abomination!
I'll summarize what I think is some of the coolest info:
Configuration, mouse improvements:
- No, the start menu isn't coming back, but the start screen and overall mouse usability/discoverability has been substantially improved.
- Ability to boot to the desktop
- Ability to make the "all apps" view your default view instead of the tiles, essentially making it work more like a full-screen start menu
- Improvements to the "all apps" view to more easily sort through your installed programs (by name, or last used, or recently installed, etc.)
- Ability to show desktop applications first in the "all apps" view instead of modern apps, if that's what you use most frequently
- Ability to use your desktop background on the start screen, so it's not as jarring
- Ability to selectively disable "hot corners"
- Shut-down / restart options added to the "Win+X" menu (or right-click on the start button)
- Ability to keep the start screen always visible on one monitor (as a dashboard) while doing stuff on another monitor
Basically, it helps respond to user feedback about confusion, jarring changes, and mouse usability, without making personalization/live tiles/etc. completely irrelevant.
New search
- Universal search returns instead of segregated search
- Instant results appear as you're typing - whether settings, programs, files, or web results
- Hitting Enter on a search takes you to the full-screen search experience shown in the screenshots in the article (which is amazing btw)
There's a lot more, but I'll mention one more thing here that I think is particularly amazing - integrated SkyDrive support. Even on a 32GB Surface you can have a 100GB SkyDrive available to you.
- Nothing syncs locally by default
- You can still selectively sync whatever you want locally
- All "online only" files still show up in Explorer.
- They can be searched, have thumbnails, etc. but barely take up any room at all. (My 45GB of data on SkyDrive takes just a few megabytes in data stored locally)
- Right when you want to open one, or some application needs one, it automatically streams from the web in the background
- "Online only" files can even be transparently used by any existing applications - desktop or modern - because the system automatically fetches them when it needs them
Definitely check out the articles - lots of big stuff I didn't mention at all.
