On May 31, Windows 8 Release Preview became available for download.
This was also announced in Delivering the Windows 8 Release Preview post with additional details on what changes were incorporated to it since the first preview last September.
Personally I haven’t tried the previous release. I only read about it. I am not fond of the new Start menu where (multi-)touch is the key of user experience. I don’t have any devices with touch. So it’s the first release of Windows that I am not excited about.
I understand the reasons why they made it that way. It’s rather expected step to converge user experiences across multiple devices. On the other hand, it assumes all new computers in offices should support touch, doesn’t it?
