Using Filter keys
 

Hhaaavvvinnngg prroobbblemmmss sssuucchhh aaasss tthiisss wwwiiitthh youurrr tttyyypinngg? Do your fingers still stumble over each other when typing a simple letter? It happens all the time even with experienced encoders and what you can do to avoid it is this.

Go to the Accessibility options link on the Control Panel in Start. Select Use Filterkeys in the Keyboard tab to activate it. Then click on the Settings button to add your preferences to it like if you want to Ignore repeated keystrokes or just Ignore quick keystrokes and slow down the repeat rate. Click OK after selection. If you can’t decide which one is better for you, try each first for a few days to determine what really works for you. Then you are off to improving your typing and computer skills. :)
