Can anyone tell me if office 2013 is likely to work on win 10 ??? Trying to get mother in law on internet (83 yr old) and she doesnt want to fork out cash every year fo office, for the little use she will get out of it, but still wants office to manage her finances and send letters to taxman etc.. (does OK on old XP at the moment) We are looking at a laptop that already has win 8.1 on it and would upgrade her (free ?) to win 10 when we upgrade our own PC's later this year
