I've got windows 7 on my laptop, and I can do the free upgrade to windows 10. All system requirements are OK. I don't really want to do the upgrade, because I like my current Windows 7. But I know in the (near) future, I will get problems, because windows 7 will get outdated. And then I want to upgrade to windows 10. It's really annoying that the free upgrade offer ends at July 29. So there's not much time left to decide.
I searched a lot on Google, and I came to the conclusion that it's possible to save the upgrade to a medium like an USB stick. But is it also possible to save it directly to my laptop's harddisc? It says if you use an USB stick, 4 GB space must be available. So it would looks very handy to me to save the upgrade to my harddisc and later do the upgrade.
I read this question ans answers: Is it possible to get Windows 10 upgrade as an ISO image (to make a bootable install disk from)? If I understand correctly: You can download a tool from the microsoft site. That tool can create an ISO file of your upgrade. You save the file and then you can upgrade (offline) whenever you want. Also when July 29 has passed, you can still use the ISO to upgrade (because that's just the point)
