I had Windws 7 with fake serial which I got converted to genuine one in a promotional offer during launch of Windows 8. I thus upgraded my WIndows 7 to WIndows 8 and now to windows 10. I wish to refresh or reinstall windows 10 . Please let me know what problems will I face? I have a Windows 8 genuine key with which can I install windows 10 directly or the key is different for win 8 n win 10?where wud I get the key for Windows 10. I dont have Windows 10 DVD too as I used to upgrade from Win 7 to Win 8 through online installer and from windows 8 to windows 10 through Windows store upgrade. How to get windows 10 refreshed in this case?Do I have to install 7 again and then get it updated to windws 8 then to win 10?
You have to install Windows 8 again with genuine serial key and then if offer is still there you can upgrade to Windows 10 for free.
Windows 8 serial key won’t work for Windows 10, so you first have to install Windows 8.
