How to backup Windows 10 upgrade
I purchased windows 8.1 and got free upgrade to Windows 10. Now my question is if I want to reinstall my OS then I only have Win 8.1 disk with me, what should I do ?. Is there any way to backup the Windows 10 upgrade or else I will have to spend long hours downloading the Win 10 upgrade all over again ?
Or If I have purchased a Windows 10 for a different system , can I use that disk in any way ?
