I am poised to upgrade mine as well.
How is your Kodi working, have you upgraded to 15 (Isengard) yet?
Yes I have KODI 15 and it's fine with Win 10.
For win 10, download the media creation tool to your desktop, ( little icon top right in pics ) then from that, download the instal.exe to a USB pen drive. Install from that, and keep it for future ref. It didn't ask for Win 7 SN, must have got it from BIOS. Also I installed to save all my apps and settings. No probs , though I did save docs, photos, & music .
