I find that disturbing, one of the first things I do after a clean install of windows is to check the "Show Hidden Files", which was hard to find in Windows 7 :/ I thought most tech savvie people did that?
I've been using Windows 7 at work for about a year, and I had absolutely no idea that the menu will show up when I hit the alt key until exactly 2 days ago. Every time I needed something from it I'd just rummage around all the visible menus, not find it, curse my head off and open up the command prompt.
I'm not sure which will look dumber as a consequence of this post: me or the Windows 7 UI.
It's due to the hidden menu, same drill with Office 2010 and finding "Save As.." etc, I've never been much for just using the keyboard, I like using the mouse to navigate the menus ;)
Maybe because of the Control Panel revamp, or the fact that the menu-bar is hidden by default in Explorer windows?
