brian.barnes :
I am considering buying a hardware bundle in where I add my own ssd O/S and gpu. Rather than spend money on a new licence of Win 10. I know it is still possible to upgrade from windows 8( a lot cheaper) under certain conditions in which apply to me. Can I assume in the meantime windows 8 will recognise ddr4 and 8th gen cpu's/motherboards to begin with
In all new hardware, your Win 8.1 will require a full reinstall.
Whether the license for that will work with new hardware depends on where it came from.
Win 10?
The safest thing is to try to Upgrade your current system to Win 10.
This may or may not work.
If it does, then you can probably transfer that license to the new hardware.
Read and do this before you change any parts:...
