What are the all possible values of Repeat Rate / Repeat Delay offered by Win 7 concerning Keyboard settings.

  • Did you check in the control panel under Keyboard settings? Or are you looking for something more specific? – bfhd Feb 9 '12 at 23:50

    For sure I did. But there are no values, expressed only in words (short/long or fast/slow). I need an exact values in miliseconds. – Stanyko Feb 9 '12 at 23:59

Check in the registry under HKEY_CURRENT_USER\Control Panel\Keyboard.

The KeyboardSpeed property determines the rate at which a character repeats when a keyboard key is held down.

This is a value in the range from 0 (approximately 2.5 repetitions per second) through 31 (approximately 30 repetitions per second). The actual repeat rates are hardware-dependent and may vary from a linear scale by as much as 20%.

The KeyboardDelay property indicates the length of time after a key is pressed and held down before keystroke repeat messages are sent by the operating system.

This value is in the range from 0 (approximately 250 millisecond delay) through 3 (approximately 1 second delay). The actual delay associated with each value may vary depending on the hardware.

    The link has been changed since I posted it, it was a direct copy/paste ;(. This is a likely replacement: technet.microsoft.com/en-us/library/cc978658.aspx – bfhd Feb 20 '13 at 19:56

Leave HKEY_CURRENT_USER\Control Panel\Keyboard alone and try [HKEY_CURRENT_USER\Control Panel\Accessibility\Keyboard Response] instead. Try the following settings which activate so-called filter keys:

[HKEY_CURRENT_USER\Control Panel\Accessibility\Keyboard Response]
"AutoRepeatDelay"="200"
"AutoRepeatRate"="6"
"DelayBeforeAcceptance"="0"
"Flags"="59"

Flags has to be 59, other values are in ms. Needs logout or restart to activate. Experiment as you wish, though I found AutoRepeatDelay less than 200 generating unneeded repeats. I tested XP Home and Prof, as well as Windows 7 64 bit, and it worked excellently.

Original values, just in case of trouble, are:

"AutoRepeatDelay"="1000"
"AutoRepeatRate"="500"
"DelayBeforeAcceptance"="1000"
"Flags"="126"
  • Thanks for posting this! I used auto-repeat value of 725 for my 1000 Hz polling rate keyboard, it was doing random repeats and this fixed it :) – Zhuinden Aug 19 '14 at 18:06
  • Total hack! But it works! – Rigel Jan 10 '18 at 12:55
  • What is bounceTime ? – Rigel Jan 10 '18 at 13:08
  • Excellent trick EXCEPT that it causes controlling keys to stick (I have my Ctrl and Win sticking even in games, completely gone after disabling this trick). – Euri Pinhollow Feb 10 '18 at 8:57
  • Worked very very well for my Windows 7 on a ThinkPad T450 previously, now restored the OS partition and I'm trying again. – Edwin Yip May 8 '18 at 8:08

For a UI alternative to modifying the registry as described by Appenzeller, this utility lets you tweak to speeds not available through the Control Panel.
