When I restart my wife's Acer Aspire laptop with Windows XP, I receive a message about "Hardware Installation". [The software you are installing for this hardware - "LegacyDriver" has not passed Windows Logo testing to verify its compatibility with Windows XP.] Of course, I always "Stop Installation". What does it do? Should I use it? If not, what do I have to do to get rid of the installation file altogether? Thanks for any help.
