Nope.
7 & 8.1 in VM's, just for testing purposes.
Vista and XP? Not enough time to mess with those.
I do have a very old laptop with Win2000 still installed. It is used once or twice a year to interface with the OBDII in my truck.
Why? Because that laptop is the only one here with a serial port.
Yes, I could buy a fancy new bluetooth, WiFi, or USB OBDII adapter. But this one works as is. Why spend the extra money to replace something that works.
That reminds me...I should crank it up on the truck this weekend.
