Windows 8 Represents a Radical Change

The lack of visual cues is apparent after login. Although Microsoft added a screen during installation that shows the use of the four corners of the screen to access critical functions, theres still nothing on the screen to remind the user.
Some vendors see business opportunities with Windows 8 complexity. Programs already exist, for example to reverse the changes in Windows 8. For instance:
- RetroUI disables the Metro Tiled Start screen and the functions in the four corners of the screen, presenting a classic Windows Desktop.
- Start8 from Stardock brings back the classic Windows 7 Start button (a globe). Windows purists may be happy, but Microsoft certainly wont be!
Suggestions for Microsoft
Windows users may find the many changes in W8 to be challenging. If I were to give a suggestion to Microsoft Id propose a tile on the Metro Start Screen called Windows 8 Training Videos Start Here! This would go a long way to help users get acclimated so they dont get frustrated.
