Agree with dtel_995 and other recent posters. Win8 was too radical a change and looks as if it has not been tested by working users as opposed to techies or players.
In case anyone has missed it, I have copied this from geggsie who posted on another thread.
" Go to Control Panel > Hardware and Sound > (under Device and Printers) click
Mouse > (Under Mouse properties) click **Device Settings Tab >**click the Settings button > un-tick the **'Enable Edge Swipe'**option > click Apply. "
This gets rid of the charms bar problem from the touch pad. The other suggestions I found did not work for me, including 3rd party offerings like winaero.
I have a Synaptics touch pad, but my driver version 17.x.x.x did not have this option. I uninstalled the 17.x.x.x driver and donwloaded and installed the older generic Synaptics 16.3.15.1 driver, and unchecked "enable edge swipe". Other touch pad functionality
seems to be fine with this older driver.
It is like getting my computer back from being hijacked by a crazy clown like the one played by Tim Curry in the movie 'It'. I cannot express how much more productive I am able to be - typing, doing graphics, web browsing, downloading, email and the rest -
without the charms bar and switch screen to the Metro interface appearing every few seconds, interrupting concentration and needing touchpad movements and keystrokes to get rid of it.
If you have a Synaptics touch pad. this is definitely worth a try. If you have a different brand, you could examine its properties and see whether
there is a corresponding option.
I do not understand why Synaptics have removed this option from the later drivers. I tried every option given by the first installed 17.x.x.x driver and the latest 17.x.x.x driver from Synaptics but nothing corresponds to this.
