Presently my PC has win-10 build 10240 installed & is working Ok. However I propose to install the new skylake motherboard, CPU & DDR4 RAM in the next 2 weeks' time. Obviously that means I'll have to re-install win-10. How do I do it?? 1st option: Can I install build 10130 afresh & then upgrade to 10240 -- OR --- 2nd option: Using new migration tool download the full 4GB file afresh & then install. My personal understanding / feel is 1st option will be better but don't know if the 10130 build will install / what about its expiry date, etc. 2nd option is not easy as my boot SSD will be totally Blank after hardware is fully changed. I may not be aware but there could be some other process as well. Request all my friends on Techspot to pls help me out by giving a quick solution / reply to me. Sure someone would have done similar activity & their experience will help me be better prepared in the matter. Thanks in advance.
