Windows – How to increase mouse sensitivity beyond limits in Windows Regedit

mouseregeditwindowswindows 7windows-registry

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)?

Best Answer

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.
