Now you tell me.
I always left click the start menu. The way Gates made it to be.
If I wanted to learn new click moves, I would have bought an Apple Mac.
I think the issue is that you want to make it harder. Consider your problem- you want to find the Control Panel. The issue, in terms of getting it done quickly, is that you feel you should be looking for it, and that it should be somewhere easy for you to find.
But realistically, we can just tell the OS to find it for us. That is what Start->Search is for, after all.
For example, when I want to start Control Panel, It is on the Apps screen. I didn't even know it was there until just now, because I open by:
1. Pressing the Windows Key
2. Typing 'Control'
3. Pressing Enter
It takes less than a second for me. Really I do this for every application, I just change what I am searching for. I've done this since Vista, because it is simply demonstrably faster and more fluent.
I'm actually not even entirely clear what the Start Menu in Windows 10 actually improves that makes so many Windows 8 haters flip-flop. The "Apps" screen that replaces the "All Programs" foldout is actually even worse than what Windows 7 or Vista provides, as it's something of a condensed view of the standard, full-screen "Apps" display. I was always under the impression that those who felt the Start Menu was critical were those who used the All Programs Menu, but now I have no idea.
Anybody Remember starting Programs with XP or earlier when you didn't have a desktop shortcut and you couldn't remember the company that made it? You want to start Mr. JellyWorld, but you don't remember that it's made by "Paula Bean Inc." so you have to drill down through all these different program folders and look through all of them, quite annoying!
