Windows 7 and windows XP have different mouse acceleration

Hi,
Does Windows 7 have different mouse acceleration than Win XP?
I notice that I´m not very comfortable using the mouse in Windows 7 as I am in Win XP.

Win XP flows much easier and faster.
Win 7 drags a bit and I sometimes I have to pick up the mouse to get from one corner of the screen to the other.
By the way, I haven´t got any drivers installed, just the plain mouse.

Is there a way to tell it to move the same as in Win XP?

This is a problem to me because I use XP at work and 7 at home, and since I work in design I have to get used to Win 7 mouse movement every time I get home.

Thanks!
Jimmy

How to change mouse speed in Windows 7? this should help you out.

Thanks, I´ve done that before but that doesn´t change Win 7 mouse acceleration, just the speed.
I would like it to behave as in Win XP.
Thanks
