Using Windows 10 Technical Preview

For the most part, if you’ve been using Windows 8 on a mouse-and-keyboard desktop PC for a while, Windows 10 Technical Preview will feel very familiar. Here are the new changes/features that immediately stood out:

Windows 10 looks a lot sharper. The new 1-pixel borders on app windows, along with the drop shadow, really does make the Windows 10 Desktop look rather smart.
The new Alt-Tab view is horrible. I’ve always hated Microsoft’s attempts to re-work the Alt-Tab app switcher into something more visual. The new Alt-Tab view in Windows 10 is pretty horrendous . Maybe it’ll be better once I get used to it — but if you’re used to a neat line of thumbnails that you can cycle through, you’re in for a shock.
Snapping is indeed much improved. In Windows 10 Technical Preview you have many more ways of snapping apps than in Windows 8. You can now snap left and right, and left and right of the middle divider on a multi-monitor setup. You can also snap in a top or bottom corner. When you snap an app, if you have other apps minimized, a new interface pops up asking if you want to snap another app into the remaining gap. It’s kind of cool. Very much a throwback to the “tile view” of yesteryear.
The Start menu is back. Personally I don’t use the Start menu much (I prefer to pin my apps to the taskbar), but yes, the Start menu is back in Windows 10 — and yes, you can remove all of the live tiles if you want.
