How to Fix a Keyboard That Has the Wrong Characters
1, Open up the Control Panel. This can be done by either pressing win+r and typing "control" (without quotes) or going to My Computer and clicking "Control Panel" in the Other Places area on the left.
2, Look for "Regional and Language Options." The categories are alphabetized, so finding it shouldn't be hard. Once you find it, double-click on it. A window should come up with the tabs "Regional Options," "Language Options," and "Advanced" at the top.
3, Look in the "Regional Options" tab, you should find a pull down menu, some "samples," and another pull down menu. Make sure that both menus are set to your region's settings.
4, Click on the "Customize" button next to the first pull down menu. Sometimes these settings can interfere with your keyboard.
5, Make sure that, at the bottom of the "Customize" dialogue, your measurement system is set to whatever system your region uses. Once that tab in "Customize" is all set, move over to "Currency," "Time," and "Date," making sure that their settings are correct.
6, Click "Apply" for both the Customize window and the Regional and Language Settings window.
7, Test out the keys using a word processing program such as Notepad or MS Word. If the problem persists, it may be a hardware issue.

If the above steps didn't work, then your keyboard may be broken.
