For Windows 8 users, Windows 8.1 is completely free. It will be available as a download from the Windows Store — that’s the “Store” app in the Modern, tiled interface.
Assuming upgrading to the final version will be just like upgrading to the preview version, you’ll likely see a “Get Windows 8.1″ pop-up that will take you to the Windows Store and guide you through the download process.
You’ll also be able to download ISO images of Windows 8.1, so can perform a clean install to upgrade. On any new computer, you can just install Windows 8.1 without going through Windows 8. New computers will start to ship with Windows 8.1 and boxed copies of Windows 8 will be replaced by boxed copies of Windows 8.1.
My husband’s new computer came with windows 8. I just had to reload my “new” iphone because the on/off button was faulty and Verizon replaced it. I am NOT updating anything for at least a month. I am getting sick of all this tech crap and am thinking of throwing it all in the garbage!!
