1. Additional Snap
Snap feature of Windows 8, which allows modern applications to run in 2/3-1/3 ratio, is now improved and allows apps to be snapped in 50-50 ratio which is a very useful feature on high resolution monitors. At most 4 apps are allowed to be snapped (by decreasing ratio from 50-50)
2. New sizes of Live Tiles
Windows Blue has introduced two new sizes of live tiles – small (as present in Windows Phone 8) and large (combination of two rows). According to me, this might not be a good option as we use Windows on large screen resolution monitors. So small tiles is not a good option and large tiles are ugly in look.
3. New Modern Applications
Windows Blue includes a number of new bundled Modern applications like Alarm, Sound Recorder, Movie Moments, Calculator etc.
4. Internet Explorer 11
In Windows Blue, Microsoft has introduced a new version of Internet Explorer. Till the time of writing this, there was no news of any new major changes in it.
5. PC Settings has been updated
6. Devices and Share charms have been updated (Share charm allows you to take a screenshot of current app)
7. New animations are added
8. Snap feature now works on even 1024 * 768 resolution
