I have heard that Windows 10 is a free upgrade. Currently I have Windows 8.1 installed (I own retail Windows 8). When I format my OS it is bad enough having to install Windows 8 then install the Windows 8.1 update. So now Will I have to install Windows 10 over that? May have to just buy the standalone disc if it ends up being a drawn out process just to format to Windows 10.
That seems unlikely. Windows 8 Retail followed by Windows 10 Upgrade would be more likely. The 8.1 step seems unnecessary.
