[dvHW] Windows 7 not compatible with older versions of Windows?

According to thebetaguy Microsoft is planning a major overhaul for their next version of Windows that should give users more performance and stability. The site claims Windows 7 will be a radical change and won't be binary compatible with previous versions of Windows:
Windows 7 takes a different approach to the componentization and backwards compatibility issues; in short, it doesn't think about them at all. Windows 7 will be a from-the-ground-up packaging of the Windows codebase; partially source, but not binary compatible with previous versions of Windows. Making the break from backwards compatibility is a dangerous proposal but a dream for software developers. Performance of native applications can be increased, distribution sizes can be cut down, functionality can be added without the worry of breaking old applications, and the overall end-user experience can be significantly improved.

However, Windows' lure has always been that applications from older versions of Windows are almost guaranteed to work post-upgrade; this is in contrast to older UNIX solutions where upgrading the system could render old applications useless without access to the source code. On an operating system which uses a binary distribution model, this is an unreasonable expectation. However, there is one company which made a success out of breaking backwards compatibility, using a method which Microsoft are seeking to emulate with the launch of Windows 7. The company in question is Apple.

I actually prefer this. With a FRESH base build upwards of Windows will mean they are going to completely overhaul the system which will hopefully remove those horrible bugs that continue to plague windows from previous versions.

That being said it will be a bummer for some as Upgrade just will not be an option. For me however I never upgrade. I always prefer a fresh install.

Although i agree with Enterprise about the fresh start, they could lose a lot of their userbase by this move.

EDIT: If they manage to succesfully run the previous versions of Windows via virtual machines, it should be ok I guess.

What? Vista is only 1 year and a few months old.They are already thinking of scraping it?LOL I think a lot of people are going to go from XP---->Windows 7. I might.Are MS thinking of commiting suicide if this is true?

Vista was a major OS release. Windows 7 will be an interim release, like a sort of stepping stone between Vista and the next major OS form Microsoft. See: http://www.overclock.net/software-ne...ml#post3674204

It's also rumoured that Windows 7 will be a subscription-based OS, so I don't think as many people will be jumping from XP to 7 as you think.

Until Microsoft releases an OS worth upgrading to, I will stick with XP. Windows 7 sounds like it has two extremes: it's an extremely good idea in some sense, and it's an extremely bad idea in some senses.

I realize that while there are many unhappy Vista owners who switched back to XP, there are many more who love Vista and wouldn't dream of using anything else right now. But for me, I don't have any need to upgrade the OS. XP Pro SP2 is what I'll have until I need to upgrade.

This will all change, XP and Vista were supposed to be "ground up" built but from what I gather they just get the old OS and change things about and introduce the new feature but never "ground up". Roll on Windows 7, hopefully I won't have to touch Vista again, but I think BF3 is going to be Vista only so I will be forced to install my Free (legit) Copy of Vista again (I would never pay for it as to me its not worth £10 let alone £100+).

How can it be legit if it's free? How did you get it for free, and how can I get it for free and still have it be legit?

If Windows 7 will be subscription based then you can count me out. I do not like the idea of that.

Really I am wonder how rumours starts and how insanely fast they spread? As for the subscription based okay if this is true then Microsoft are really trying to lose their competitive marketshare.
