Recommend an Offline Maps Program for PC – Europe?

I am traveling to Europe soon, and I will be driving from country to country sightseeing … I need a good maps app in case I’m out of any free wifi range to keep me on the right path. I don’t want to buy a GPS, I have it built into my car, and won’t have a use for it after I come back.
I know for North America there is Microsoft Streets and Trips, but I need something for Europe instead..
Please advise, your help is appreciated.
