I understand that there's a notification that comes up on Windows 7 about installing Windows 10. What if I don't want to install it now, but want to download it now and install it maybe in a few months or a year or two? Is that possible?
Yes, you can. Download the media creating tool
Run the tool and you will be asked whether to "Upgrade PC now" or "Create installation media for another PC".
Choose "Create installation media for another PC" and select the language and windows version to download.
It will then ask you whether you want to create a bootable USB or download ISO.
If you have a spare USB flash drive then select the first option and specify the drive and it will download and install it on that drive.
Otherwise chose download ISO where you can store it in your PC and create a DVD from it once you decide To install the Windows.
Sort of. Basically MS isn't going to upgrade your older versions to newer versions in perpetuity. This isn't a freebie - its an attempt to get people on the latest version, and on the windows 10 tracks.
While you can create media now and upgrade later, there's a point where the licence activation for upgrades may not work. Its also unclear what happens with the older licences (as far as I can tell).
So, in a few months? Maybe. After the end of the year - if you already activated a windows 10 install? Also maybe. Now to the end of next july? Maybe. After july? Naw, not happening.
I just imaged my systems, gave win10 a shot, and if I had issues, I could fall back to the old versions.
