I will be writing a comprehensive review of this build shortly, in which I’ll elaborate on just how nice these features are when put to use. They actually had to implement a feature that lets you set boot options prior to restarting. One thing that I found to be quite humorous is that Microsoft actually added a feature called 'boot forward' see, due to the vastly improved boot times in Windows 8, it would be tough or impossible to pull up a boot options menu (i.e by pressing F8). So, what’s new in the build? Some of the more noteworthy improvements include OS-wide spell check (this is huge it’s a feature that has been requested by a lot of people for years), the replacement of the Start button with what is called a 'Start preview thumbnail' – which displays a preview of the start screen on top of an interface that allows you to cycle through all of your open apps – and the introduction of 'Flyout' notifications. Today is the big day for those of you who have been anticipating some fresh new Windows 8 bits to toy with: Following an official debut right next door to the Mobile World Congress – not specifically at it, it’s a little side event at the Hotel Miramar in Barcelona – Microsoft has just officially released the Windows 8 Consumer Preview.
