Why does XP randomly reset itself to the US keyboard layout?

Question

I sometimes find that " and @ have swapped places. There's no pattern to it that I can discern. It can happen in the middle of the day.

Answer 1

Maybe you've inadvertently been hitting ALT+SHIFT? That's the Windows shortcut for switching inputlanguages. If so, you could uninstall the English keyboard layout, like so:

1. Go to Control Panel / Regional and Language Settings / Language Settings / Details.
2. Under "installed services", mark "English US" and hit the "Remove" button next to the list.
