A video look at Windows 10 features #InHomeComputerSetUpHonolulu
Presently, for those running Windows 8 or 8.1. In the lower right hand corner of your screen there's a window icon (picture). If you click on it you can get a free copy of Windows 10 when it's ready. DO NOT download it from any other source. Windows 7 users, at this time I'm not recommending the upgrade. Going up two upgrades with a new system could cause some problems.
