Finally Windows 10 is there! I'm running it on Surface Pro 3 for a while and don't want to go back to Windows 8.1 anymore :) Microsoft has released Windows 10 for all customers worldwide now, using Windows Update or the ISO's available. Next wait is for Windows 10 Mobile which is expected somewhere in October this year.
Before you begin, make sure you have:
-An internet connection (internet service provider fees may apply).
-Sufficient data storage available on a computer, USB or external drive for the download.
-A blank USB or DVD (and DVD burner) with at least 4 GB of space if you want to create media.
-If you will be installing the operating system for the first time, you will need your Windows product key.
