How to disable mouse acceleration in Windows Vista SP1?

I'm a Counter-Strike player.
Before Vista SP1, I use game parameter "-noforcemaccel" and the following
registry to remove mouse acceleration. I works fine in Windows XP and
Vista(With no SP1).

===============================================================================
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Mouse]
"SmoothMouseXCurve"=hex:00,00,00,00,00,00,00,00,00,a0,00,00,00,00,00,00,00,40,\
01,00,00,00,00,00,00,80,02,00,00,00,00,00,00,00,05,00,00,00,00,00
"SmoothMouseYCurve"=hex:00,00,00,00,00,00,00,00,66,a6,02,00,00,00,00,00,cd,4c,\
05,00,00,00,00,00,a0,99,0a,00,00,00,00,00,38,33,15,00,00,00,00,00

But after I updated to Vista SP1, it does not work anymore.
I've asked all around but still no solution there.

Can anyone do me a favor that how to disable MOUSE ACCELERATION in Windows
Vista SP1?

Thanks very much.

i have exactly the same problem
Iam playuing cs 1.6 and when i had no sp1 installed it worked fine with theese setting to launch options "-noforcemaccel -noforcemparms -noforcemspd" and also Ive turned off the accel in mouse settings in control panel
but after I installed the sp1 on my vista business 32bit, my mouse is moving smoother or dunno what happend , just it is not making the accurate move i want from it to do ...

hello, i registered just to post this: there is a workaround! use the flags in the shortcut as mentioned above and... play in windowed mode! yes it sucks but i'd rather live with that than having screwed up aim.

this thread might have been dead, but it was also one of the top search results i got while googling this problem. and after all this time, the mouse acceleration is still a real problem so i'm sure someone will find my post useful

Right.

Very good..
Problem half solved..
=)

That not that bad playing in window..
