Some people have noticed that they are experiencing
a really slow shutdown after installing Windows XP Home
or Professional. Although this can be caused a number
of ways, the most clear cut one so far is happening
on systems with an NVidia card installed with the latest
set of drivers. A service called NVIDIA Driver Helper
Service is loading up on start up and for whatever reason
doesn't shut itself down properly. The service isn't
needed and can also increase the amount of memory available
to your system. Here is how to disable it.
1: Go into your Control Panel
2: Select Administrative Tools and then click on Services
3: Right click on the file "NVIDIA Driver Helper
Service" and then select STOP.
4: To stop this loading up every time you boot up your
PC Right click it again and select properties - then
where the option "Startup Type" is shown
