Upgrades my WIN7 Lenovo to WIN 10, all went well. Took it down and plugged it into the car, went KOEO and fired up powerlooger. Hit F8 for monitor and got the dreaded multi beeps that meant no monitor hook up. Bummer. Closed powerlogger, and restarted it, hit F8 and bingo, all works well. Never saw it do a driver search.
