Microsoft will move the graphics for its next version of Windows outside of the operating system's kernel to improve reliability, the software giant has told Techworld. Vista's graphics subsystem, codenamed Avalon and formally known as the Windows Presentation Foundation, will be pulled out the kernel because many lock-ups are the result of the GUI freezing, Microsoft infrastructure architect Giovanni Marchetti told us exclusively yesterday.
The company has already announced to developers that most drivers, including graphics, will run in user mode - which means that they don't get access to the privileged kernel mode (or Ring 0). At this level, a process can do anything it likes, including overwriting memory that doesn't belong to it. The result of such overwriting by (usually) buggy code is often a system crash. So the move should result in greater reliability, because crashing drivers cause some 89 per cent of system crashes in Windows XP, according to Microsoft. When run in user mode, they won't be able to bring down the entire system.

Microsoft will Ship All Vista Bits with Each Product Edition
QUOTE
Although Microsoft will market several Vista product editions, or SKUs, the company will distribute one version of the product's DVD providing the code for all product editions on each disc. That way, users will be able to unlock functionality from higher-end Vista editions at a later date, after paying for the upgrade privilege. The change in plans, which was first reported by "CRN," means that Microsoft will need to maintain only a single Vista master disk image rather than the multiple images that would otherwise be required. Each time a Vista edition is upgraded, Microsoft will provide an updated product key, as each product edition requires different product key sequences. At that point, your old product key will be invalidated so it can't be used on a different system. Say what you will, but this new scheme makes a lot of sense, given the sheer number of email messages I get about upgrading one edition of XP to another. And with Vista, we'll see even more product editions, each with its own specific set of features.
