I have an HP Elitebook 8570W laptop.
I get lots and lots of typos because the keyboard "thinks" I accidentally hit two keys. nonononono! I just type very fast.
Is there any way to change the debounce time of this keyboard?

I found an article on hp which says to decrease the keyboard debounce time in the registry, however on my Windows 7 this time was zero. Maybe this zero says "use default" or maybe this zero means the debounce is done by the hardware.
Anyway, I changed it to 35 ms and later to 20 ms and it seems to have worked as I have much less typos than before. The registry key is:
HKEY_CURRENT_USER\Control Panel\Accessibility\Keyboard Response\BounceTime

Those settings are generally related to OS, so please post your operating system too. Also, what are the typos, why do you think you type too fast? – Máté Juhász – 2018-02-18T16:30:43.967
@MátéJuhász, the typos are any double key such as "aa", "oo" etcetera and any two keys hit in rapid sucession (using ten fingers). And I don't think I type too fast, I know it. Ever used a real IBM101 keyboard? That lets you type really fast! – Paul Ogilvie – 2018-02-27T09:13:23.100
are you talking about double clicks? I have noticed double clicks that i don't make, and i hope your answer will help. – Alexander Myravjev – 2020-02-04T12:14:15.710
@AlexanderMyravjev, I believe the hardware/software considers any two keystrokes that fall within the bounce time as a typing error and only considers the first keystroke, ignoring the second. Formally, though, the debounce time has to do that an electrical/mechanical contact can have "sparks" when pressed that would be seen as multiple keystrokes but that should be ignored. – Paul Ogilvie – 2020-02-04T14:20:04.557
