I am having an odd problem. My keys won't repeat when held down. its fine to type and I can double touch just fine. however I can't hold and repeat. This problem has prevented movement in games that require holding down the keys to move forward. I have checked and filter keys is off and so is sticky keys. I have cleaned up my registry several time and this hasn't solved the problem. I have also restored old versions of windows 7 even going back as have as 4 years ago the problem is still there. Can anyone help?
This just happened to me and it's because my cat was lying on the keyboard I think.
If you hold down the right shift button for 8 seconds in Windows, Filter Keys turns on which limits the number of keystrokes so you can press one key only once in a 1-2 second period. This limits your ability to type any words with double letters in them, limits your scrolling with the arrow keys on websites, limits using the delete button, etc.
In Windows 7, the option to turn this off is under "Ease of Access Center" settings and then-->"Make the keyboard easier to use", then uncheck the box for "Turn on Filter Keys" in the control panel. It's not listed under Keyboard or Mouse settings.
I hope this helps someone else.
