Upgrading Boot camp 3.0 => Boot Camp 4.0

[MJL]

Just a quick note: Boot Camp 4.0 does not uninstall the Boot Camp 3.0 drivers. Potentially those can conflict.

The only one that I found that made a difference is on the mid 2010 Mac Mini the Nvidia graphics driver gives a .1 point higher rating in Windows Experience index.

update: I have reverted to the Boot Camp 3.0 - my Kensington Trackball started jerking and moving on its own. After the revert (a restore) I went into the BootCamp 4.0 CD and went to the drivers folder where I located the Nvidia drivers and upgraded only those.

Update 2: a complete removal of the boot camp 3.0 drivers and subsequent install of bootcamp 4.0 has proven to be working fine over the past two days.
(under windows I use Total Uninstall to remove any installed programs, it keeps a far better track of the changes than the normal included uninstallers which often leave remnants behind in the registry)
