I know this has probably been asked a million times, so I'm sorry. (the info must be buried in the forum) I have tried searching but I can't find answers.
If I upgrade to windows 10 am I on a "timed" version i.e. after a year or two (or any time in the future for that matter) will windows ask me to pay for the software?
How hard is it revert back from windows 10 to windows 7?
