Amazing, I didn't know Microsoft hardwired the Charms bar gestures into the touchpad. But this does kind of make sense. Microsoft just wants Charms bar to work as well as possible.
Your information has worked for me, as soon as I saw your pictures I remembered using such touchpas settings on a laptop ages ago.
I thank you for taking the time to help me, and in return I will now give the exact sequence of settings for any Classic Shell users trying to find these on an Acer ASpire S5-391 running Windows 8 (ELAN touchpad).
1. Press Windows+R to bring up the "Run field"
2. In the Run field, type: Control Panel
3. Menu "Control Panel" appears with 8 icons
4. Click the name "Hardware and Sound"
5. The menu changes shape into a two column style
6. Left-click on the word "Mouse" found under "Hardware and Sound"
7. Menu "Properties for Mouse" appears with 6 Tabs
8. Click on the right-most Tab claaed "ELAN"
9. On this Tab, click the button "Preferences..."
10. Menu "Elan Smart-Pad" appears with 3 Tabs
Here you can change in detail any swipings you don't want. In my case I stayed on the first Tab called "One-finger" and left-clicked the bottom of 4 pictures "Corner swipe". And here I simply UNchecked the check box "Activate", leaving it empty. Then I clicked "Apply".
Immediately after the Right swipe (Right-to-Left motion) produced no more Charms Bar, simply the mouse curser travelled across the Desktop. Just like I want it.
Note that there are many more settings in this "Elan Smart-Pad" menu that I did not explore, there are ways of changing how clicks and click-n-drag are handled. As well as multi-finger operations (zooming) and Sensitivity.
Thanks again, GauravK, for explaining how Microsoft has wired the gestures into the hardware. This topic has been resolved.
