I will be buying a new cheap laptop with either Windows 7 or 8.1 in the future. I won't buy a new PC with Windows 10 since I'm sure it will be more expensive. I'm just a student and will be using my scholarship grant to buy one. Can I upgrade my system to Windows 10? I haven't read something about upgrading without reservation. Thanks!
Yes you don't need to reserve Win10. Just upgrade manually with a Win10 DVD image, or use the upgrade process with Windows update until August 2016.
