Have to install pointing device on each boot

[Guest]

I have an IBM Thinkpad z61m. Everytime I boot the machine it tells me that
it is installing the UltraNav pointing device and that it hasn't passed
Microsoft certification. It asks if it should continue anyway or stop the
installation. My question is, why does it have to install it on each boot?
I have downloaded and installed the latest drivers for that device. What is
wrong and how do I fix this?

Thanks for your help.

The usual reason this occurs is that the manufacturers install sequence
was not followed and the operating system "rediscovers" the hardware
each time it starts up because of "missing" registry entries. Since this
hardware came as part of the computer, the drivers should have been part
of the factory install image. Did you replace the operating system on
this laptop? I would likely try doing a "uninstall" of the hardware,
then install the new drivers and reboot.
