Previously, there were two versions of Windows 8 that were released by Microsoft. These are the Windows 8 Developer Preview and the Consumer Preview. However, both are still considered to be the beta version on which a lot of amendments are still needed to be applied. The same cannot be said about this new preview which is the Windows 8 Release Preview.
This particular version of Windows 8 has its advantages. First of all, this is as close as you can get with the final version of Windows 8. In this build, all of the applications that were meant to be on Windows 8 are made available. The only difference is that if the final version will have a few bugs and fixes sorted out.
Inside the Release Preview, there were a few enhancement made and this includes three new applications, a “Flip Ahead” browser gesture, Flash support, multi-monitor support and a few others. In addition to that, there are also words that Wikipedia and Box.net will each release their own app for the new operating system.
If you have Consumer Preview, you will have to make a clean installation of the Release Preview. All of the personal settings will retain if you have a Live ID. If not, you will have to start from zero.
