hi i have downloaded win 10 pro 64 bit iso file (10240 )from MS website. after clean installation the window need activation. is there any way to activate win 10 . best regards
I thinks you need clean install previous version firts and activated. And then upgrade on to windows 10
Upgrade your non-Enterprise, activated Win7/8.1 system using Windows 10 PRO ISO. Once the upgraded system is activated, do a clean installation using the Windows 10 Pro ISO. NOTE: Can't exactly vouch for it, but good folks have said "internet connectivity" is necessary while upgrading for an activated, upgraded system.
