Windows XP Mouse Acceleration Fix (.exe File)

================================

Many gamers were having problems with unwanted mouse acceleration under Windows XP.

This was caused by a faulty API call ("SystemParametersInfo") which unintendedly enabled mouse acceleration even if it had been disabled previously.

There were some registry fixes aimed at disabling this acceleration, but they did not succeed.

This patcher does not try to solve the symptom like the registry fixes did, but disables mouse acceleration at its origin, the system driver ("win32k.sys").

If you have never noticed any unwanted mouse acceleration, you do not need to apply this patch.

Suported OS:

- Windows 2000

- Windows 2000 SP2

- Windows 2000 SP4

- Windows 2000 SP4 with Update Roll-Up 1

- Windows XP

- Windows XP SP1

- Windows XP SP2

- Windows Server 2003

- Windows Server 2003 SP1

sorry to bump an old thread but ineed to know how to undo this. I want my acceleration back..I have Windows

XP 64 bit.

I tried deleting the changes it made in the registry, but whenever I try to enable pointer precision, my mouse freezes and I have to disable it to get my mouse back.

any help would be appreciated..

If nothing else works, try this :

[HKEY_CURRENT_USER\Control Panel\Mouse]
"ActiveWindowTracking"=dword:00000000
"DoubleClickHeight"="4"
"DoubleClickSpeed"="500"
"DoubleClickWidth"="4"
"MouseSensitivity"="12"
"MouseSpeed"="1"
"MouseThreshold1"="6"
"SmoothMouseXCurve"=hex:00,00,00,00,00,00,00,00,15,6e,00,00,00,00,00,00,00,40,\
  01,00,00,00,00,00,29,dc,03,00,00,00,00,00,00,00,28,00,00,00,00,00
"SmoothMouseYCurve"=hex:00,00,00,00,00,00,00,00,b8,5e,01,00,00,00,00,00,cd,4c,\

You will need to extract the original Win32k.sys from the fileset.
