hey guys, i have an old desktop.. it was upgraded from Win7 "ahem" copy to Win10 ori copy by Microsoft years ago..I'm planning to reformat it, just wondering what are the steps that I should do? I'm not that IT savvy..
Is it download a Win10 copy from Microsoft website and load into USB first and use that to format? And how do I activate it? I don't think I have a windows key..
Microsoft Windows 10 (V.2)
