I finally managed to get the Windows 8 Release Preview installed. I'm typing this on Semagic while running Windows 8, but Semagic keeps giving me errors that lead me to believe that the file virtualization feature of User Account Control is not working properly. Semagic is based on an ancient version of the Microsoft Foundation Classes, which is probably why it doesn't work right. Anyway, they changed various graphical elements. The fish motif for booting Windows 8 is gone and replaced with something that simply says "Windows". The cursors are slightly modified, and all the various controls (combo boxes, check boxes, text boxes, buttons, etc.) are all flat. The scroll bars look like they're bringing the Metro look (i.e., everything should be huge) over to the desktop. The little arrows at the top and bottom are more than twice the size they were in Windows 7. A lot of the icons are different, such as the Windows Update icon just being a rectangle with wannabe recycling arrows. (The EULA doesn't allow me to show you what that looks like, even though anyone could get the Release Preview and install it themselves.) The first thing I did was uninstall a bunch of the apps that came with it. Many of the apps that come with the Release Preview didn't come with the Consumer Preview and vice versa. ( And it keeps going )
I don't feel particularly enthusiastic about going back into Windows 8. I liked the release candidates of Windows 7 and XP, but it seems 8 is about as exciting as Vista and Me.
