Since they haven't said how the upgrade will work I am going to assume it is probably going to be much like the 8 to 8.1 upgrade, provided in the store which means a clean install wont be possible.
Probably going to have to buy a new copy to do that which is fine. I got 8 for $15 bucks so I wont complain at having to buy 10.
I've been using the technical preview since September. With each new build, things have grown less stable. The first build was ironically one of the best. They have a lot of bug smashing to do before July.
Its Windows 8 with a start menu. I've been using the preview for a while now and there is little diff between Windows 8 and Windows 10, which is a good thing I guess when it comes to people migrating from windows 8 or even 7, but it's nothing that's going to set new records by any means. although I do suspect it to be more popular then windows 8, but I don't know if I can say the same about windows 7. my biggest gripes are, there is still no option to revert the start menu back to the classic start menu. ms still wants to push its metro stuff onto people in some shape way or form, by jamming it into the start menu. i'm not a fan of the ribbon navigation menu either, the navigation menus in windows vista and windows 7 worked just fine, I wish there was a way for ms to have an option of a classic windows 7 style windows navigation menu to choose from instead.
Odds are that the Windows 7 computers that are not getting the free upgrade to windows 10 are not capable of running Windows 8. Although the system requirements look the same they are not. Starting with Windows 8 PAE, NX, and SSE2 were required to be implemented in the CPU and supported by the chipset. Without those functions available Windows 8 will not install (at least I have not been able to get it to install). Those same requirements are likely preventing some windows 7 computers from ever running anything beyond Windows 7.For those who aren't eligible for the free W10 upgrade, it would be nice to see Microsoft at least offer W10 (even if for a limited time) to everyone else for a low introductory price of no more than $25 USD. C'mon, Microsoft! You can do that!
7 to 10Just made my windows 10 reservation yesterday.
I really really really hope I can install windows 10 fresh, without needing to install windows 8, then 8.1, then windows 10.
I tried Windows 10 and offers nothing worth upgrading over Windows 7 not to mention how ugly it looks. No, thanks.
