It appears that your Windows keyboard layout has been switched
from QWERTY to Dvorak http://en.wikipedia.org/wiki/Dvorak_Simplified_Keyboard

Windows keeps a separate keyboard layout setting for each running application.
The keyboard layout setting is connected to the Windows language setting.
Windows keeps a separate combination of language and keyboard layout,
for each running application.
So Windows can give one application English (US) + QWERTY keyboard,
another application English (US) + Dvorak keyboard, and a third
application English (UK) + QWERTY keyboard.

1. Windows can switch language + keyboard on certain keystrokes.
Very occasionally I find mine has jumped into Chinese (Simplified) + MSPinYin
in some application.
2. The other thing I would suggest doing, is displaying the Language bar
on the desktop so you can open it, see what keyboard is being used
with the current program, and change the language or keyboard back.
I have not used Vista. On Win7, the settings would be at
Control Panel >> Region and Language >> Keyboards and Languages
Click the "Change Keyboards" button, and
(1) Select the "Advanced Key Settings" and set all key sequences to "none".
(2) Select the "Language Bar" tab and configure Windows to show the
language bar. When the problem happens again, the Language Bar may
let you get out of the Dvorak keyboard layout and back to QWERTY.
