Microsoft has completely re-thought the design and added the new metro interface, new apps support which is the major break through in windows 8.

it includes a whole new interface and UI which you might find a little bit difficult to use but once use it for a day or two you will love it . there is a lot of flexibility ,you can install new apps from the store the new metro UI .





with a completely re-thought design and UI micrisoft has preserved the old windows 7 experience in it too.

there are only still about a 100 apps in the store but I am sure that most have the developers have started to develop for the metro style apps for windows 8 and the apps should be out before the launch of windows 8 in October.

music app

Microsoft includes some built in apps like music and video app which is pretty sweet .
it contains a rich UI and we can buy or rent music and videos

video app

Store

The store is also made in the metro UI and includes a lot of different categories and we are waiting when these will get flooded with new apps


all new IE10

One more plus point in windows 8 is that you get the new IE10 which is also pretty cool .But Microsoft has to improve a lot in it before it is out in its final release .But off-course you can always switch back to the desktop IE .

it syncs with Microsoft account and keeps the settings backed up


One more that Microsoft has added in windows 8 is that is smooth like Buttter
even in the release preview  the are no lags the computer boots up just in 10-20 secs which is extremely fast. You can watch the video below to note the boot time .
