Windows 10 -- Or an older version of Windows that I can upgrade to Windows 10; Pro if possible
Building a system and want to install Windows 10. I'm having trouble finding any kind of good deals on Windows 10, especially pro. Not sure if I can buy an older windows and still get free auto-update? Also, not sure about whether the guys selling Windows 10 on amazon are shady (possible gray market if not counterfeit products).
Thanks in advance!!
