Jose has updated to Windows 10, will he have to pay for the update after one year? Leo says no, the free upgrade was only a window of one year to upgrade. After July 29th, you'll have to buy it if you don't upgrade. So upgrade, activate. And then downgrade just so you have access to it in the future, because once you've updated, it's free forever. And Leo thinks that Windows 10 will just keep getting updated and this could be the last version of Windows coming.
But Jose has installed Windows 10 and it still hasn't activated after a month. Leo says it should activate almost immediately if you have a legit previous copy of Windows. So if it's not activating, then you need to contact Microsoft before it locks you out.
