On XP or Vista (or even Win7)??????????
For XP go to Start\Set Program Access and Defaults\Change or Remove Programs.
Then scroll down to nVidia and click on 'nVidia Drivers' then click the 'Change/Remove' button.
Be aware that when the old ones are removed it will want to reboot and when it does it will come back at 800x600 resolution (as it has no video drivers) so it will look odd and all your desktop shortcuts will look huge.
Install the new drivers and reboot and you should be good to go apart from sorting out all your shortcuts as they will all be clumped together if you had them arranged in any way before.
I have XP - this driver set won't install. For Vista and Windows 7 only says the error message. 191.07 works OK for me though.
