How do I turn off auto-accent in Windows 7?

Solution 1:

In your Regional Settings, instead of an English | US keyboard, you have selected English | United States (International). Possibly, your default system language has also been changed from "US" to "United States / Intl"

Just change it back to US and it should be fine.

Solution 2:

Pressing ctrl-shift (using the left shift key) will toggle accents for some keyboard configurations.

Solution 3:

If you need multi language support, it would be better to turn on Language Bar so you could switch input language on the fly on any program. If language bar is on your desktop already, you might want to try to switch it to EN to type in English without the auto corrections.

If you did not had language bar or just wanted to remove your non-English input support. Go to the "Region and Language" option in control panel, click on "Change keyboards and input methods". Then click the change keyboards button and from here you could add or remove the keyboards you want, then go to the Language Bar tab to configure where you want to show the language bar.
