I want to increase mouse sensitivity beyond the limits set in Windows 7 Control Panel. I found various mouse sensitivity settings in regedit under HKEY_CURRENT_USER\Control Panel\Mouse.

Can I increase mouse speed and senstivity there (which is limited in control panel)?

  • Increase pointer speed in main.cpl control panel or Command: reg add "HKCU\Control Panel\Mouse" /v "MouseSensitivity" /d "20" /f – Biswapriyo Oct 15 '17 at 20:00

    The best way to increase mouse sensitivity beyond the limits of your mouse is to buy a better mouse. Depending on your budget and needs, there are magnificent mice to be had. – harrymc Feb 24 at 17:59

In regedit, there are three settings in the registry correlated to changes in the speed setting of mouse control panel:

HKEY_CURRENT_USER\Control Panel\Mouse\MouseSpeed
HKEY_CURRENT_USER\Control Panel\Mouse\MouseThreshold1
HKEY_CURRENT_USER\Control Panel\Mouse\MouseThreshold2

The MouseSpeed key maxes at 2 from control panel, and increasing this above 2 will cause the mouse to slow down, since it doesn't accept values above 2.

The mouse speed is a multiplier for MouseThreshold1 and MouseThreshold2, which correlate to acceleration.

To increase mouse sensitivity to maximum:

  1. Set MouseSpeed to 2.
  2. Set MouseThreshold1 to 0.
  3. Set MouseThreshold2 to 0.

You may want to set MouseThreshold1 and MouseThreshold2 a little higher than 0 if your pointer becomes a little too jumpy on the screen, but make sure that MouseThreshold2 is greater or equal to MouseThreshold1, and all three of these are integer values.

    How do you refresh the settings? I tried with SendMessage, 0x1A,,,, ahk_id 0xFFF in autohotkey it didn't work. Also tried fooling around with the mouse dialog but it seemed to reset all my settings with values in dialog. – Ciantic Mar 5 '13 at 9:32

  • I'm guessing it's just a restart will do it – markasoftware Oct 21 '14 at 22:43

    Given that the settings are under HKEY_CURRENT_USER, it's probably sufficient for reloading the settings to log the current user out and then log back in rather than a full system restart. – steamer25 Jun 18 '15 at 14:44

    -1 because the answer does not discuss how to increase mouse sensitivity BEYOND the limit. The current settings you've identified refer to documentation about settings that are automatically set in the Registry by using the control panel, and hence do not discuss increasing beyond the limit – Dan Nissenbaum Sep 15 '15 at 3:40

As MoE bis said, you need to edit the mouse acceleration curve. This refers to the registry keys

HKEY_CURRENT_USER\Control Panel\Mouse\SmoothMouseXCurve
HKEY_CURRENT_USER\Control Panel\Mouse\SmoothMouseYCurve

You can of course edit these values with the built-in registry editor, but it is more convenient to use the CustomCurve (direct download, archive link) application. This requires .NET Framework 4.0 or newer.

CustomCurve application

I quote the short guide from the website:

Generally speaking:

  • The X value of a point represents how fast you move the mouse.
  • The Y value represents how much the cursor moves in response.

For a more in-depth explanation about the mouse acceleration curve, see this article.

  • Does it also works for Windows 10? – wonsuc Apr 22 '18 at 21:06

The existing answers either do not work in Windows 10 or have no meaning, belonging to the old days when DPI was around 400, and Microsoft was making efforts to enhance its IntelliPoint software beyond hardware capabilities. Even when they work, these configuration parameters may at most set mouse sensitivity to the hardware's maximum, but not beyond that.

Today, the mouse tracking technology has advanced to a point that it doesn't make any sense for the consumer to understand, examining so many variables from which very few are under user control.

To be convinced, you may listen to this video of a Logitech engineer explaining DPI:

enter image description here

Dots per inch (DPI) stays the single most important parameter under user control for changing the measure of sensitivity. Almost all mouses sold today have about 1600 DPI. Gaming mouses usually have 4000 DPI or more, and can be increased/decreased by pressing a button on the mouse.

DPI is more of a marketing ploy for gaming mouse. In fact, many competitive first-person shooter game players set their mouse DPI to 1200 or even 800, because lower DPI gives you precision/sensitivity.

The most one can do for increasing mouse sensitivity is to get a sophisticated high-DPI mouse with a sophisticated driver externalizing adjustable parameters and the ability to define multiple usage profiles to account for the different conditions when employing different software products. Such mouses can usually change profiles at the press of a button, thus changing mouse sensitivity (among others).

  1. Run regedit.exe from the Windows search bar
  2. Go to HKEY_CURRENT_USER\Control Panel\Mouse
  3. Change MouseSensivity to 20 (10 = normal, 20 = twice as fast)
  4. Restart your PC
