windows 8.1

Hi, would anyone still have AMD chipset drivers for Windows 8.1 x64 still? Seems odd that most AMD motherboards only have chipset support for Windows 10 and 7 but dropped 8.1. If anything you'd think with Windows 7 being the oldest they'd drop in order of oldest and not drop the middle! Works...

Not sure if I'm technically allowed to ask this on here so apologies if anything. I currently have Windows 8.1 and want to upgrade to Windows 10. It's my wife's photo editing computer and I do not want to mess anything up in the process. Am I able to still upgrade to Windows 10 by using my 8.1...
