Random guessing is no way to learn an upgrade.
None of these occurred to me at random.
When I accidentally moved the mouse to the bottom left corner, a Start button did appear. It was located a few dozen pixels up and right of the corner. Based on previous experience with Windows, I assumed it was button and I needed to click on it. When I moved my mouse out of the immediate corner to position it on that button, it disappeared! I repeated the cycle several times, convinced that either my mouse wasn't compatible or that i was doing something unimaginably wrong. Nothing in previous versions of Windows prepared me to click without having the cursor on the 'button' I wanted to activate; my learned behavior of positioning the cursor on the button before clicking was actually counterproductive.
Equally, nothing led me to think anything would result from just dragging along an edge, or just randomly typing outside a box or prompt. It never did anything before; why would it occur to me to try it now? If I moved into a new house, I wouldn't think to go around randomly pushing on the walls or turning on the water faucets in random combinations. Nothing in previous homes would lead me to expect secret walls or free beer.
Yes, training would have resolved all of my issues. That's been my major point all along. We IT types have time to wade through an F1 menu or to Google these things. It's the costs of training end users and the loss of productivity while they unlearn old habits that will stall corporate implementation.
The list of previously fruitless behaviors is too large to randomly guess which ones to try first. This is (supposedly) an operating system, not a video game where I should expect to Google for cheat codes.
