A while back I wrote how to change the handedness (which seems to be the correct term, instead of the dreadful ‘Menu on the wrong side with a touch screen’).
I got a machine in my hands which exhibited the previously mentioned problem. However Tablet PC Settings weren’t installed, so we couldn’t open the tab.
After searching the bowels of the internet I found the following shell shortcut:
Putting this in Winkey+R, or in the Windows 7/8(.1) search box will open the Tablet PC Settings, and if you don’t have a touch screen, will default to the Other tab, where you can change the handedness of your menus!
Have a good one,
